| 2) **From Gemini to Q-Star** - A 300+-paper survey mapping the state of Generative AI and the research frontiers that followed the Gemini + rumored Q* news cycle.  <br>● Broad coverage: Surveys developments across language, vision, audio, and multimodal generative systems, treating Gen AI as a unified field rather than siloed modalities.  <br>● Computational challenges: Catalogs scalability, efficiency, and alignment challenges currently gating further progress, including training compute, inference serving, and evaluation.  <br>● Real-world applications: Reviews Gen AI impact across healthcare, finance, and education, highlighting where genuine deployment signals diverge from hype.  <br>● Future directions: Identifies agent frameworks, reasoning, grounded multimodality, and alignment as the most live research areas heading into 2024. | [Paper](https://arxiv.org/abs/2312.10868), [Tweet](https://x.com/omarsar0/status/1740119485011390558?s=20) |
| 3) **PromptBench** - A unified library for comprehensive evaluation and analysis of LLMs that consolidates multiple evaluation concerns under one roof.  <br>● Prompt-construction tooling: Ships with utilities for prompt construction, prompt engineering, and dataset/model loading, covering the end-to-end LLM evaluation workflow.  <br>● Adversarial prompt attacks: Built-in adversarial prompt-attack capabilities let users stress-test LLMs against perturbations rather than just measuring clean accuracy.  <br>● Dynamic evaluation: Supports dynamic evaluation protocols to detect dataset contamination and measure robustness beyond static benchmark numbers.  <br>● Unified interface: Replaces the ad-hoc evaluation scripts many teams maintain with a consistent API, reducing friction when comparing across models and prompt variants. | [Paper](https://arxiv.org/abs/2312.07910v1), [Tweet](https://x.com/omarsar0/status/1739360426134028631?s=20) |
| 4) **Exploiting Novel GPT-4 APIs** - A red-team study of three newer GPT-4 API surfaces - fine-tuning, function calling, and knowledge retrieval - that reveals each introduces new attack vectors.  <br>● Fine-tuning strips safeguards: As few as 15 harmful examples - or even 100 benign examples - fine-tuned into GPT-4 is enough to remove core safety behaviors.  <br>● Function-call schema leakage: GPT-4 Assistants can be coerced into divulging their function-call schemas and then tricked into executing arbitrary function calls.  <br>● Retrieval hijacking: The knowledge-retrieval endpoint is vulnerable to prompt injection via documents in the retrieval corpus, letting attackers steer model behavior through uploaded content.  <br>● Policy implication: Expanding API surface area introduces alignment risks that weren't present for text-only completions, and API providers need surface-specific defenses rather than relying on base-model alignment. | [Paper](https://arxiv.org/abs/2312.14302), [Tweet](https://x.com/omarsar0/status/1739677995747450964?s=20) |
| 5) **Fact Recalling in LLMs** - A mechanistic-interpretability study showing that early MLP layers function as a lookup table for factual recall.  <br>● Athletes-to-sports task: Scoped to how Pythia 2.8B recalls which of 3 different sports various athletes play - a clean task for dissecting a single type of factual recall.  <br>● Early MLPs as lookup table: Early MLP layers perform a structured lookup rather than distributed reasoning, with specific neurons keyed to entity-attribute pairs.  <br>● Multi-token embedding view: Recommends treating factual knowledge recall as operating over multi-token embeddings rather than single-token representations.  <br>● Interpretability payoff: Provides a concrete, testable account of where and how facts live inside transformers, enabling targeted editing and auditing of parametric memory. | [Paper](https://www.alignmentforum.org/s/hpWHhjvjn67LJ4xXX/p/iGuwZTHWb6DFY3sKB), [Tweet](https://x.com/NeelNanda5/status/1738559368361349122?s=20) |
| 6) **Generative AI for Math (OpenWebMath / MathPile)** - Releases a diverse, high-quality math-centric corpus of ~9.5B tokens designed for training math-capable foundation models.  <br>● 9.5B-token corpus: Curated from mathematical content across the web, textbooks, papers, and Q&A, rebalanced for math-specific token distribution.  <br>● Quality filtering: Applies math-specific filtering to surface content dense in symbolic notation, proofs, and problem solutions rather than surface-level mentions of math.  <br>● Diverse sources: Explicitly mixes proof-heavy formal math with applied problem-solving to avoid over-fitting to any single mathematical register.  <br>● Training signal: Positioned as a drop-in pretraining or continual-pretraining corpus to lift math reasoning in existing LLMs without changing the architecture. | [Paper](https://arxiv.org/abs/2312.17120), [Tweet](https://x.com/arankomatsuzaki/status/1740564961032556942?s=20) |
| 7) **Principled Instructions Are All You Need** - Distills effective LLM prompting into 26 guiding principles and validates them across multiple model families.  <br>● 26 principles: Covers prompt structure, audience specification, example selection, formatting, role assignment, and stepwise decomposition.  <br>● Broad model validation: Tested on LLaMA-1/2 (7B, 13B, 70B) and GPT-3.5/4, finding the principles generalize across scales and families.  <br>● Both small and large benefits: Smaller models benefit more from structured prompting (higher variance reduction), while larger models benefit in absolute accuracy on harder tasks.  <br>● Practical reference: Functions as a cheat-sheet for practitioners, converting scattered prompting folklore into testable recipes. | [Paper](https://arxiv.org/abs/2312.16171v1), [Tweet](https://x.com/_akhaliq/status/1739857456161759455?s=20) |
| 8) **Survey of Reasoning with Foundation Models** - A comprehensive survey of reasoning with foundation models, covering tasks, methods, benchmarks, and future directions.  <br>● Task coverage: Surveys math reasoning, commonsense reasoning, logical reasoning, symbolic reasoning, and multimodal reasoning - showing how each evolves with model scale.  <br>● Methodology catalog: Covers prompting techniques (CoT, ToT, self-consistency), fine-tuning strategies, and neurosymbolic approaches under a unified framework.  <br>● Benchmarks: Systematizes the reasoning benchmarks landscape and flags contamination and robustness concerns specific to reasoning evaluation.  <br>● Adjacencies: Discusses how multimodal learning, autonomous agents, and super-alignment research intersect with and extend the reasoning agenda. | [Paper](https://arxiv.org/abs/2312.11562v4), [Tweet](https://x.com/omarsar0/status/1740729489661874632?s=20) |
| 9) **LLaRA** - LLaRA adapts a decoder-only LLM for dense retrieval via two tailored pretext tasks that leverage text embeddings from the LLM itself.  <br>● EBAE pretext task: Embedding-Based Auto-Encoding uses LLM embeddings to reconstruct tokens of the input sentence, aligning the embedding space with semantic content.  <br>● EBAR pretext task: Embedding-Based Auto-Regression predicts tokens of the next sentence from the current embedding, injecting discourse-level signal into retrieval embeddings.  <br>● LLaMA 2 7B base: A LLaMA 2-7B base model is adapted into a retriever with these pretext tasks, yielding significant gains on MSMARCO and BEIR.  <br>● Decoder retrievers validated: Provides another data point that decoder-only LLMs, with the right adaptation, rival specialized encoder retrievers - a theme that continued through 2024. | [Paper](https://arxiv.org/abs/2312.15503v1) |
| 10) **Gemini vs GPT-4V** - A qualitative side-by-side comparison of Gemini and GPT-4V across vision-language tasks, documenting systematic behavioral differences.  <br>● Head-to-head cases: Evaluates both models on a curated set of tasks covering document understanding, chart reading, everyday scenes, and multi-image reasoning.  <br>● GPT-4V style: Produces precise, succinct answers with strong preference for brevity and factual minimalism.  <br>● Gemini style: Returns more expansive, narrative answers frequently accompanied by relevant images and links - leveraging its deeper integration with search.  <br>● Complementary strengths: Concludes that the models are substitutable for many core VLM tasks but differ sharply on response length, multimedia, and augmentation patterns. | [Paper](https://arxiv.org/abs/2312.15011v1), [Tweet](https://x.com/omarsar0/status/1741177994377330895?s=20) |

## Top AI Papers of the Week (December 18 - December 24)
| **Paper**  | **Links** |
| ------------- | ------------- |
| 1) **Gemini's Language Abilities** - CMU's impartial, reproducible evaluation of Gemini Pro against GPT and Mixtral across standard LLM benchmarks.  <br>● Reproducible methodology: Provides an open, reproducible evaluation pipeline - a response to concerns about Google's own Gemini launch benchmarks being hard to independently verify.  <br>● Gemini Pro vs. GPT 3.5 Turbo: Gemini Pro achieves comparable but slightly lower accuracy than GPT 3.5 Turbo, countering marketing claims of broad parity on language tasks.  <br>● Gemini & GPT beat Mixtral: Both Gemini and GPT outperform Mixtral on these benchmarks, suggesting open mixture-of-experts has not yet closed the gap to frontier proprietary models.  <br>● Evaluation norms: Positioned as evidence that independent replications remain essential, and that first-party model reports shouldn't be the final word on comparative capability. | [Paper](https://arxiv.org/abs/2312.11444), [Tweet](https://x.com/gneubig/status/1737108966931673191?s=20)|
| 2) **PowerInfer** - A high-speed LLM inference engine for consumer GPUs that exploits sparse neuron activation patterns to run large models on commodity hardware.  <br>● Hot/cold neurons: Analysis shows that a small fraction of "hot" neurons activate on most inputs while the majority of "cold" neurons activate rarely - a power-law pattern across many LLMs.  <br>● GPU-CPU hybrid: Hot neurons are preloaded onto the GPU for fast access, while cold neurons live on the CPU and are computed lazily, dramatically reducing GPU memory pressure.  <br>● Reduced memory + transfer: This split reduces both GPU memory demand and the CPU-GPU data transfer that typically dominates hybrid inference cost.  <br>● 11x speedup over llama.cpp: Achieves up to ~11x faster token generation than llama.cpp on a single consumer GPU for OPT-175B-class models - a step-change for local deployment. | [Paper](https://ipads.se.sjtu.edu.cn/_media/publications/powerinfer-20231219.pdf), [Tweet](https://x.com/omarsar0/status/1737168751668187229?s=20)|
| 3) **Antibiotic Discovery with Graph Deep Learning (Nature)** - MIT researchers use explainable graph neural networks to discover a new structural class of antibiotics.  <br>● Graph neural networks: Trains GNNs on molecular graphs to predict antibiotic activity, with explainability layers that surface chemical substructures driving predictions.  <br>● Explainable discovery: Unlike black-box property predictors, the explanation module identifies substructures underlying antibiotic activity - a feature drug chemists can actually use.  <br>● New structural class: The discovered compounds belong to a novel structural class, not a variant of existing antibiotic scaffolds - an unusually strong generalization signal.  <br>● Real-world pipeline: Demonstrates end-to-end pipeline from GNN prediction to wet-lab validation, reinforcing explainable ML as a practical discovery tool for biomedicine. | [Paper](https://www.nature.com/articles/s41586-023-06887-8), [Tweet](https://x.com/EricTopol/status/1737505177052348545?s=20)|
| 4) **VideoPoet** - Google Research's VideoPoet is a large language model for zero-shot video generation that treats video as just another token stream.  <br>● Unified token stream: Uses multiple tokenizers to map video, image, audio, and text into a shared discrete token space for a single autoregressive model.  <br>● Zero-shot task variety: The same model handles image-to-video, video stylization, video-to-audio, and text-to-video without task-specific fine-tuning.  <br>● Language-model paradigm: Demonstrates that a plain autoregressive LM, given the right tokenizers, can handle video generation - challenging the diffusion-everywhere default for video.  <br>● Temporal consistency: Produces videos with reasonable motion coherence over short durations, a meaningful milestone for LM-based video generation. | [Paper](https://sites.research.google/videopoet/), [Tweet](https://x.com/GoogleAI/status/1737235593078456389?s=20)_|
| 5) **AppAgent** - Introduces an LLM-based multimodal agent that operates real smartphone apps through touch actions and screenshots.  <br>● Multimodal control: The agent reads the phone screen (visual input) and issues low-level touch actions (tap, swipe, type), operating apps the way humans do rather than via APIs.  <br>● Two learning modes: Learns new apps either via autonomous exploration (discovering functionality through self-play) or by observing human demonstrations.  <br>● Cross-app generality: Demonstrates proficiency across email, social media, shopping, and creative apps, suggesting that multimodal LLMs can generalize across smartphone UIs.  <br>● Early mobile-agent blueprint: An early example of the on-device multimodal agent pattern that would become a major 2024 deployment theme. | [Paper](https://arxiv.org/abs/2312.13771), [Tweet](https://x.com/omarsar0/status/1738265651188253051?s=20)_|
| 6) **LLM in a Flash** - Apple researchers show how to run LLMs larger than available DRAM by streaming weights from flash storage on demand.  <br>● Flash as swap: Stores model weights on flash and streams only the rows/columns needed per forward pass into DRAM, exploiting the sparsity of relevant parameters.  <br>● 2x DRAM headroom: Enables running models up to 2x the size of available DRAM without catastrophic slowdown, critical for on-device deployment where memory is tight.  <br>● Major speedups vs. naive loading: 4-5x faster on CPU and 20-25x faster on GPU compared to naive parameter loading, thanks to selective transfer and row-column bundling.  <br>● On-device LLM groundwork: Directly enabled Apple's later on-device LLM plans by showing that flash-based streaming can make phone-scale LLM inference practical. | [Paper](https://arxiv.org/abs/2312.11514), [Tweet](https://x.com/gabrielnocode/status/1737307286887133552?s=20)_|
| 7) **ReST Meets ReAct** - Proposes a ReAct-style agent that improves itself via reinforced self-training on its own reasoning traces.  <br>● Self-critique ReAct: A ReAct-style agent with a self-critique step that evaluates its own reasoning and answers, generating a filterable trace dataset.  <br>● ReST-style iterative RL: Uses growing-batch RL from AI feedback to iteratively fine-tune on the agent's successful reasoning traces, improving over rounds without human labels.  <br>● Human-label-free: Minimizes human involvement; synthetic data with self-improvement from AI feedback is the primary training signal throughout.  <br>● Distillation to small models: The improved agent can be distilled into models 1-2 orders of magnitude smaller with comparable performance, dramatically cutting inference cost. | [Paper](https://arxiv.org/abs/2312.10003), [Tweet](https://x.com/omarsar0/status/1736587397830176910?s=20)_|
| 8) **Adversarial Attacks on GPT-4** - Demonstrates that a trivially simple random-search procedure can jailbreak GPT-4 with high reliability.  <br>● Adversarial suffix: Appends a suffix to a harmful request and iteratively perturbs it, keeping changes that increase the log-probability of the response starting with "Sure".  <br>● No gradients needed: Operates purely via the API in a black-box setting, without model gradients or weights - a much lower bar than prior white-box jailbreak work.  <br>● Strong success rate: Achieves high attack-success rates on GPT-4 with a small number of API calls, despite ongoing alignment efforts.  <br>● Alignment implication: Shows that current safety training is still vulnerable to near-trivial optimization attacks, pointing to the need for stronger behavioral defenses. | [Paper](https://www.andriushchenko.me/gpt4adv.pdf), [Tweet](https://x.com/maksym_andr/status/1737844601891983563?s=20)_|
| 9) **RAG for LLMs** - A broad survey of Retrieval-Augmented Generation research, organizing the rapidly growing literature into a coherent map.  <br>● Three-paradigm taxonomy: Organizes RAG approaches into Naive RAG, Advanced RAG (pre/post-retrieval enhancements), and Modular RAG (orchestrated component-based systems).  <br>● Core components: Reviews retrievers, generators, and augmentation strategies separately, clarifying which design choices sit in which component.  <br>● Evaluation and datasets: Catalogs RAG-specific benchmarks and evaluation metrics, surfacing the still-uneven state of RAG evaluation.  <br>● Frontier directions: Highlights agentic retrieval, multimodal RAG, and long-context RAG as the key research areas driving the 2024 RAG landscape. | [Paper](https://arxiv.org/abs/2312.10997v1), [Tweet](https://x.com/omarsar0/status/1738354427759612222?s=20)_|
| 10) **BabyLLM Challenge Findings** - Reports results from a challenge on sample-efficient pretraining using a developmentally plausible corpus.  <br>● Constrained pretraining: Participants pretrain on a small, child-directed-style corpus rather than on internet-scale data, testing how efficiently models can learn from limited input.  <br>● LTG BERT wins: The winning submission, LTG BERT, beat Llama 2 70B on 3 of 4 evaluations despite vastly less training data.  <br>● Data preprocessing pays: Strong-performing entries relied heavily on data preprocessing and training on shorter contexts, challenging assumptions about long-context training for small data.  <br>● Cognitive-science bridge: Provides an empirical platform connecting language-model training to developmental psycholinguistics, informing both fields. | [Paper](https://aclanthology.org/volumes/2023.conll-babylm/), [Tweet](https://x.com/a_stadt/status/1737849248560066794?s=20)_|

## Top AI Papers of the Week (December 11 - December 17)
| **Paper**  | **Links** |
| ------------- | ------------- |
| 1) **FunSearch** - DeepMind's FunSearch uses LLMs as a mutation operator in an evolutionary loop to discover genuinely new mathematical knowledge.  <br>● LLM + evaluator loop: Combines a pretrained LLM that proposes candidate programs with a systematic evaluator that scores them, iteratively evolving low-scoring programs into high-scoring ones.  <br>● New math discoveries: Produces novel solutions to open problems in combinatorics, including cap-set and online bin-packing, not memorized from the training data.  <br>● Hallucination mitigation: The evaluator acts as a hard filter - only programs that actually work are kept - so LLM hallucinations don't propagate into the "discovered" knowledge.  <br>● General recipe: Positions LLM-in-the-loop search as a general tool for scientific discovery beyond math, applicable wherever candidates can be automatically scored. | [Paper](https://www.nature.com/articles/s41586-023-06924-6), [Tweet](https://x.com/GoogleDeepMind/status/1735332722208284797?s=20) |
| 2) **Weak-to-Strong Generalization** - OpenAI's superalignment team shows that weak supervisors can still elicit capabilities from much stronger models - a first empirical signal for scalable oversight.  <br>● Weak-to-strong setup: A weak model (e.g., GPT-2) generates labels, and a strong pretrained model (e.g., GPT-4) is fine-tuned on those labels - an analog of humans supervising superhuman AI.  <br>● Better than the supervisor: Naively fine-tuning the strong model on weak-model labels often yields a model better than the supervisor itself, demonstrating useful capability elicitation.  <br>● ~GPT-3.5 from GPT-2 supervision: Fine-tuning GPT-4 with GPT-2-level supervision recovers close to GPT-3.5-level performance on NLP tasks - a surprising amount of capability without strong labels.  <br>● Superalignment signal: Offers an early empirical footing for the bet that humans can align superhuman systems using their own (weaker) judgments - provided the right training recipe. | [Paper](https://cdn.openai.com/papers/weak-to-strong-generalization.pdf), [Tweet](https://x.com/OpenAI/status/1735349718765715913?s=20) |
| 3) **Audiobox** - Meta's Audiobox is a unified flow-matching audio model that generates speech, sound effects, and music from natural-language and example prompts.  <br>● Unified audio generation: Single model handles speech, sound, and music - ending the typical pattern of one model per audio modality.  <br>● Description + example prompting: Supports both natural-language descriptions and reference-audio examples for style control, letting users mix semantic and acoustic conditioning.  <br>● Self-supervised infilling: Adapts a self-supervised infilling objective to pretrain on large unlabeled audio, reducing dependence on scarce labeled speech/music datasets.  <br>● Novel voice/styles: Unlocks generation of novel vocal and acoustic styles by interpolating in the learned audio space, going beyond reproduction of training-set styles. | [Paper](https://ai.meta.com/research/publications/audiobox-unified-audio-generation-with-natural-language-prompts/), [Tweet](https://x.com/AIatMeta/status/1734257634008531453?s=20) |
| 4) **Mathematical LLMs Survey** - A survey on the progress of LLMs on mathematical reasoning tasks, covering methods, benchmarks, and open problems.  <br>● Task taxonomy: Covers math word problem solving, symbolic reasoning, and theorem proving, showing which capabilities emerge at which model scales.  <br>● Methods landscape: Reviews prompting techniques (CoT, PoT, ToT, self-verification) alongside fine-tuning and tool-use approaches.  <br>● Dataset reference: Catalogs the dominant math benchmarks (GSM8K, MATH, MiniF2F, etc.) and their evaluation methodologies.  <br>● Frontier problems: Highlights reasoning-faithfulness, formal-vs-informal math integration, and reward-model design as the key open questions. | [Paper](https://arxiv.org/abs/2312.07622), [Tweet](https://x.com/omarsar0/status/1735323577392542084?s=20) |
| 5) **LLM360** - LLM360 is a framework for fully transparent open-source LLM development, with everything from data to training dynamics released.  <br>● End-to-end transparency: Ships training code, the pretraining corpus, intermediate checkpoints, evaluation code, and analyses - going well beyond the "just weights" openness of earlier "open" LLMs.  <br>● Two 7B models: Releases AMBER (general) and CRYSTALCODER (code-specialized) 7B models pretrained from scratch under the framework.  <br>● Enables training-dynamics research: Intermediate checkpoints let researchers study loss trajectories, emergent capabilities, and data-effect ablations - typically only possible inside frontier labs.  <br>● Standard for openness: Pushes the community's definition of "open-source LLM" from weights to a full training-pipeline standard. | [Paper](https://arxiv.org/abs/2312.06550), [Tweet](https://x.com/omarsar0/status/1734591071575744820?s=20) |
| 6) **LLMs in Medicine** - A comprehensive survey (300+ papers) of LLMs applied to medicine, from clinical tasks to biomedical research.  <br>● Principles and applications: Covers the core principles of medical LLMs and their applications across clinical decision support, patient communication, medical education, and biomedical research.  <br>● Benchmark coverage: Reviews medical QA benchmarks (MedQA, PubMedQA, MedMCQA, etc.) and their limitations for real clinical settings.  <br>● Challenges: Identifies challenges specific to medicine including hallucination in clinical advice, privacy, regulatory compliance, and equity/bias concerns.  <br>● Deployment considerations: Discusses what's required for safe deployment, including evaluation, monitoring, and the role of clinician oversight. | [Paper](https://arxiv.org/abs/2311.05112), [Tweet](https://x.com/omarsar0/status/1734599425568231513?s=20) |
| 7) **Beyond Human Data (ReST-EM)** - DeepMind's ReST-EM shows that model-generated data plus a reward function can substantially reduce dependence on human-generated data.  <br>● Expectation-Maximization framing: Generates candidate solutions from the current model, filters using a reward/verifier, and fine-tunes on the filtered set - repeat.  <br>● Verifiable rewards: Uses automatic verifiers (e.g., correct-answer checks) as the reward signal, sidestepping the need for a learned reward model on scarce tasks.  <br>● PaLM 2 gains: Scales effectively on PaLM 2 for math and code tasks, outperforming standard SFT on human data at matched compute.  <br>● Synthetic-data signal: A strong empirical case that self-generated filtered data can replace much of the human data bottleneck for reasoning tasks - a theme that grew through 2024. | [Paper](https://arxiv.org/abs/2312.06585), [Tweet](https://x.com/omarsar0/status/1734953578274386002?s=20) |
| 8) **Gaussian-SLAM** - A neural RGBD SLAM method that extends 3D Gaussian Splatting to achieve photorealistic scene reconstruction without sacrificing speed.  <br>● 3D Gaussians for SLAM: Represents scenes as 3D Gaussians rather than neural fields, inheriting the fast training and rendering of Gaussian Splatting.  <br>● Photorealistic reconstruction: Produces significantly higher-fidelity reconstructions than prior neural SLAM methods at comparable or better runtime.  <br>● RGBD input: Uses standard RGB+depth input streams, making it compatible with off-the-shelf depth cameras for practical deployment.  <br>● Speed/quality Pareto: Advances the Pareto frontier for RGBD SLAM, where previous methods forced a trade-off between runtime and photorealism. | [Paper](https://vladimiryugay.github.io/gaussian_slam/), [Tweet](https://x.com/vlyug/status/1734683948440252480?s=20) |
| 9) **Pearl** - Meta's Pearl is a production-ready reinforcement learning agent package designed for real-world deployment constraints.  <br>● Production-oriented design: Built for real-world environments with limited observability, sparse feedback, and high stochasticity - conditions that usually break research-oriented RL libraries.  <br>● Modular components: Offers modular policy networks, exploration strategies, offline RL, and safety constraints that can be composed for specific applications.  <br>● Research + practice: Targets both researchers building new RL agents and practitioners deploying RL in production recommender systems, ranking, and control.  <br>● Meta internal use: Reflects learnings from Meta's internal deployments, making it a rare RL library that starts from production pain rather than benchmark scores. | [Paper](https://arxiv.org/abs/2312.03814), [Tweet](https://x.com/ZheqingZhu/status/1732880717263352149?s=20) |
| 10) **QuIP#** - Cornell's QuIP# is a 2-bit LLM quantization scheme that combines lattice codebooks with incoherence processing to close the quality gap to FP16.  <br>● Lattice codebooks: Uses E8 lattice codebooks for weight quantization, a classical lattice-quantization technique adapted to LLM weight matrices.  <br>● Incoherence processing: Pre-processes weight matrices to make them "incoherent" (less structured along axes), which improves lattice-quantization fidelity.  <br>● 2-bit at 16-bit quality: Significantly closes the gap between 2-bit quantized LLMs and their unquantized 16-bit counterparts across a range of LLaMA-family models.  <br>● Deployment impact: Makes large LLMs (e.g., Llama 2 70B) fit into consumer-grade GPU memory without catastrophic quality loss, expanding the set of models hobbyists can run locally. | [Paper](https://cornell-relaxml.github.io/quip-sharp/), [Tweet](https://x.com/tsengalb99/status/1733222467953422702?s=20) |

| 2) **EfficientSAM** - Meta's EfficientSAM is a lightweight Segment Anything variant that preserves most of SAM's zero-shot quality at a fraction of the compute.  <br>● Masked autoencoder pretraining: Uses a SAMI (SAM-leveraged masked image) pretraining objective where a small student learns to reconstruct features aligned with the SAM teacher.  <br>● 20x smaller and faster: Achieves roughly 20x fewer parameters and 20x faster runtime than the original SAM image encoder.  <br>● Near-parity quality: 44.4 AP vs. 46.5 AP on zero-shot instance segmentation (within 2 points) despite the dramatic efficiency win.  <br>● Deployment-ready: Makes SAM-grade segmentation feasible on commodity hardware, consumer devices, and real-time applications where the original SAM is too heavy. | [Paper](https://arxiv.org/abs/2312.00863), [Tweet](https://x.com/fiandola/status/1732171016783180132?s=20)  |
| 3) **Magicoder** - Magicoder is a fully open-source code LLM that closes the gap with top commercial code models at only 7B parameters via high-quality synthetic instruction data.  <br>● OSS-Instruct data: Generates 75K synthetic instruction pairs by seeding GPT with snippets pulled from open-source code, producing more diverse and realistic training data than prior code SFT datasets.  <br>● Broad coverage: Training data spans Python, multilingual programming, and data-science program completion, producing a genuinely general code model rather than a Python-only model.  <br>● HumanEval+ win: MagicoderS-CL-7B (based on CodeLlama) surpasses ChatGPT on HumanEval+ with 66.5 vs. 65.9 pass@1, despite being 7B.  <br>● Fully open: Ships with code, data, and weights, positioning Magicoder as a reproducible open baseline for instruction-tuned code generation. | [Paper](https://arxiv.org/abs/2312.02120), [Tweet](https://x.com/omarsar0/status/1732063926613946863?s=20)  |
| 4) **LLMs on Graphs** - A comprehensive overview of the many ways LLMs can be applied to graph-structured data and when each pattern is useful.  <br>● Three graph scenarios: Organizes the space by whether graphs are pure (no text), text-rich (nodes/edges carry natural language), or text-paired (graphs alongside documents).  <br>● Three role taxonomies: Categorizes LLMs as predictors, enhancers, or aligners with GNNs - clarifying whether the LLM is the model, a feature source, or a supervisor.  <br>● Task coverage: Spans node classification, link prediction, graph-level tasks, and reasoning over knowledge graphs.  <br>● Open problems: Flags scalability to large graphs, handling of graph structure without loss, and integration with tool-augmented LLMs as the key unsolved directions. | [Paper](https://arxiv.org/abs/2312.02783), [Tweet](https://x.com/omarsar0/status/1732404393037762588?s=20)  |
| 5) **Llama Guard** - Meta's Llama Guard is a compact, instruction-tuned safety classifier built on Llama 2-7B for input/output moderation in conversational AI.  <br>● Llama 2-7B base: Small enough to run inline with a main generative model while handling both prompt- and response-level safety classification.  <br>● Customizable taxonomy: The safety taxonomy is specified in the instruction prompt itself, so operators can adapt it to their use case without retraining.  <br>● Zero-shot and few-shot: Works off the shelf for many taxonomies in zero- or few-shot mode, and can be fine-tuned on a specific policy dataset when needed.  <br>● Open release: Ships as an open model, filling a gap for teams that want local, auditable safety classification rather than relying solely on API-side moderation. | [Paper](https://ai.meta.com/research/publications/llama-guard-llm-based-input-output-safeguard-for-human-ai-conversations/), [Tweet](https://x.com/omarsar0/status/1732781628139696279?s=20)  |
| 6) **KTO (Kahneman-Tversky Optimization)** - Contextual AI introduces KTO, an alignment objective derived from prospect theory that works with binary "good/bad" signals instead of preference pairs.  <br>● Prospect-theory motivation: Models reward as a Kahneman-Tversky value function with loss aversion, replacing DPO's log-likelihood-of-preferences objective with utility maximization.  <br>● No preference pairs needed: Works with unpaired good/bad signals, dramatically loosening data collection requirements compared to DPO or RLHF.  <br>● Matches/beats DPO: Matches or exceeds DPO performance at model scales from 1B to 30B, a clean empirical win at similar training cost.  <br>● Practical data advantage: Makes alignment much cheaper to run in production where paired preference data is rare but outcome feedback ("user liked/didn't like") is abundant. | [Paper](https://github.com/ContextualAI/HALOs/blob/main/assets/report.pdf), [Tweet](https://x.com/ethayarajh/status/1732837520784957476?s=20)  |
| 7) **Chain of Code** - DeepMind's Chain of Code extends CoT by encouraging LMs to write pseudocode that mixes real code with LM-simulated sub-routines.  <br>● LMulator: The LM generates pseudocode programs and explicitly annotates sub-tasks that can't be executed; a "LMulator" simulates those sub-tasks with the LM while the interpreter handles the rest.  <br>● Undefined-behavior handling: The interpreter catches undefined behavior and cleanly hands off to the LM, sidestepping the brittleness of code-first approaches that fail silently on hard ops.  <br>● 84% on BIG-Bench Hard: Achieves 84% on BIG-Bench Hard - a 12-point gain over Chain of Thought and a clean demonstration that mixing exact execution with LM simulation beats either alone.  <br>● Broad applicability: Works across math, logic, and commonsense reasoning, positioning Chain of Code as a general-purpose CoT upgrade. | [Paper](https://arxiv.org/abs/2312.04474), [Tweet](https://x.com/ChengshuEricLi/status/1733169631949701425?s=20)  |

| 9) **RankZephyr** - RankZephyr is an open-source LLM for listwise zero-shot reranking that bridges the effectiveness gap with GPT-4.  <br>● Listwise zero-shot: Reranks a full candidate list in a single shot rather than doing pairwise or pointwise scoring, matching the paradigm GPT-4 uses most effectively.  <br>● Open-source: Based on the open Zephyr chat model, releasing a fully reproducible stack for high-quality reranking.  <br>● Matches/beats GPT-4: Competitive with GPT-4 on standard reranking benchmarks and outperforms GPT-4 on NovelEval, a post-training-cutoff benchmark resistant to contamination.  <br>● Contamination-free win: The NovelEval advantage is particularly meaningful because it addresses the concern that GPT-4's strong reranking numbers are partly driven by memorization of benchmark queries. | [Paper](https://arxiv.org/abs/2312.02724), [Tweet](https://x.com/lintool/status/1732430269485867114?s=20)  |
| 10) **The Efficiency Spectrum of LLMs** - A comprehensive review of algorithmic advancements for improving LLM efficiency across the full training-to-inference stack.  <br>● Scaling laws and data: Covers how scaling laws and data-utilization strategies interact with efficiency - more isn't always better under compute constraints.  <br>● Architectural innovations: Reviews attention variants, state-space models, MoE, and other architectural levers for efficient scaling.  <br>● Training and tuning: Catalogs PEFT methods (LoRA, adapters, prefix tuning), quantization-aware training, and curriculum-based training strategies.  <br>● Inference techniques: Surveys quantization, pruning, speculative decoding, KV-cache optimization, and batching as the inference-time efficiency toolkit. | [Paper](https://arxiv.org/abs/2312.00678), [Tweet](https://x.com/omarsar0/status/1731696419457606048?s=20)  |

| 6) **Medprompt** - Microsoft researchers show that careful prompt engineering can push general-purpose GPT-4 to state-of-the-art on medical benchmarks, no domain fine-tuning required.  <br>● General-purpose prompting: Uses purely general-purpose prompt-engineering techniques (CoT, dynamic few-shot, choice-shuffling ensembling) with no medical-domain specialization.  <br>● Medprompt recipe: Combines k-nearest-neighbor example selection, GPT-4-generated chain-of-thought rationales, and choice-shuffling to cancel answer-position biases.  <br>● SoTA on 9 benchmarks: Achieves state-of-the-art on all nine benchmarks in MultiMedQA, beating Med-PaLM 2 and other specialized medical models.  <br>● Broader lesson: Reopens the question of whether domain-specific pretraining is actually necessary when a frontier base model is paired with strong prompting - a framing that has recurred in later debates. | [Paper](https://arxiv.org/abs/2311.16452), [Tweet](https://x.com/erichorvitz/status/1729854235443884385?s=20) |
| 7) **UniIR** - UniIR is a unified instruction-guided multimodal retriever that handles eight retrieval tasks across modalities with a single model.  <br>● Instruction-guided: A single retriever conditioned on natural-language instructions determines which retrieval task to perform, rather than one retriever per task.  <br>● Eight tasks: Handles image-to-text, text-to-image, composed-image retrieval, video retrieval, and other multimodal variants under one umbrella.  <br>● Zero-shot generalization: Generalizes to unseen retrieval tasks not explicitly trained on, approaching a truly general multimodal retrieval model.  <br>● M-BEIR benchmark: Ships with a new multimodal retrieval benchmark (M-BEIR) designed to standardize evaluation across tasks and modalities. | [Paper](https://arxiv.org/abs/2311.17136), [Tweet](https://x.com/CongWei1230/status/1730307767469068476?s=20) |

## Top AI Papers of the Week (November 20 - November 26)
| **Paper**  | **Links** |
| ------------- | ------------- |
| 1) **System 2 Attention (S2A)** - Meta's S2A uses the LLM's own reasoning to decide what context actually matters, regenerating a clean prompt before the final response step.  <br>● Two-pass prompting: First pass uses the LLM to filter/regenerate the input context, removing irrelevant or misleading content; second pass generates the final answer from the clean context.  <br>● Addresses distraction: Directly targets the well-known problem that LLMs attend to irrelevant or manipulative content (e.g., opinion-laden context that biases answers).  <br>● Factuality gains: Increases factuality on QA and reduces the model's sensitivity to biased framing or distractors inserted into the prompt.  <br>● Math word problems: Outperforms standard attention-based LLMs on math word problems, where filtering irrelevant details is often the hard part of the task. | [Paper](https://arxiv.org/abs/2311.11829), [Tweet](https://x.com/jaseweston/status/1726784511357157618?s=20) |
| 2) **Advancing Long-Context LLMs** - A survey of methodologies for improving Transformer long-context capability across pretraining, fine-tuning, and inference stages.  <br>● Full-stack coverage: Organizes methods by training stage - pretraining objectives, position encoding, fine-tuning recipes, and inference-time interventions.  <br>● Position-encoding deep dive: Reviews RoPE variants, ALiBi, and other positional-encoding choices that dominate long-context extrapolation.  <br>● Efficient attention: Catalogs sparse, linear, and memory-augmented attention mechanisms that make longer contexts tractable.  <br>● Evaluation considerations: Addresses benchmark limitations including the "needle in a haystack" problem and the gap between nominal context length and effective usable context. | [Paper](https://arxiv.org/abs/2311.12351), [Tweet](https://x.com/omarsar0/status/1727358484360945750?s=20) |
| 3) **Parallel Speculative Sampling** - Amazon researchers propose a parallel variant of speculative sampling that achieves significant LLM inference speedups with minimal extra parameters.  <br>● Parallel decoding: Combines speculative sampling with parallel decoding so multiple tokens can be generated and verified in a single pass.  <br>● Tiny overhead: Requires learning only O(d_emb) additional parameters, far fewer than typical speculative-decoding draft models.  <br>● Up to 30% speedup: Achieves up to 30% end-to-end inference speedup without compromising output quality.  <br>● Minimal integration cost: Unlike separate-draft-model speculative decoding, this fits inside the main model with essentially no deployment overhead. | [Paper](https://arxiv.org/abs/2311.13581), [Tweet](https://x.com/omarsar0/status/1728066181796418009?s=20) |
| 4) **Mirasol3B** - Google's Mirasol3B is a multimodal model that decouples modalities into focused autoregressive components rather than forcing a single fused stream.  <br>● Decoupled autoregressive modeling: Separates audio/video processing from text processing into focused autoregressive components that communicate through learned cross-modal interfaces.  <br>● Handles longer videos: The decoupled design lets the model handle longer video inputs than typical end-to-end multimodal models constrained by sequence length.  <br>● Modality-specific processing: Inputs are processed according to their modalities with appropriate tokenization rather than forcing a one-size-fits-all tokenizer.  <br>● SoTA on video benchmarks: Outperforms prior methods on video QA, long-video QA, and audio-video-text benchmarks, validating the decoupled approach. | [Paper](https://arxiv.org/abs/2311.05698), [Tweet](https://x.com/GoogleAI/status/1724553024088191211?s=20) |
| 5) **Teaching Small LMs to Reason** - An approach that teaches smaller language models to explicitly select among reasoning techniques for each problem.  <br>● Reasoning technique menu: Trains the small LM to choose among step-by-step processing, recall-then-generate, recall-reason-generate, extract-generate, and direct-answer strategies.  <br>● Technique selection: The model learns when to apply each strategy based on problem structure, not just which answer to produce.  <br>● Matches 5-10x larger models: Attains zero-shot reasoning performance similar or better than models 5-10x larger on complex reasoning tasks.  <br>● Practical scaling: Offers a recipe for teams that can't deploy frontier-scale models but need strong reasoning quality - a recurring production constraint. | [Paper](https://arxiv.org/abs/2311.11045), [Tweet](https://x.com/omarsar0/status/1726990087399915995?s=20) |
| 6) **GPQA** - A graduate-level Google-proof QA benchmark designed to stress-test reasoning in systems that might exceed human expertise.  <br>● 448 expert questions: Consists of 448 multiple-choice questions written by domain experts in biology, physics, and chemistry.  <br>● Google-proof by design: Questions are constructed so that even with unrestricted internet access, non-experts (~34%) perform only slightly better than random on them.  <br>● GPT-4 gets 39%: The strongest GPT-4 baseline hits only 39% accuracy, showing a clear headroom for frontier models on expert-level reasoning.  <br>● Scalable oversight testbed: Explicitly designed to enable scalable oversight research - experiments in supervising models whose knowledge may exceed the supervisors'. | [Paper](https://arxiv.org/abs/2311.12022), [Tweet](https://x.com/idavidrein/status/1727033002234909060?s=20) |
| 7) **Hitchhiker's Guide From CoT to Agents** - A survey mapping the conceptual evolution from chain-of-thought reasoning to modern language-agent frameworks.  <br>● CoT foundations: Covers the mechanics underpinning CoT (few-shot prompting, self-consistency, least-to-most, tree-of-thought) with a consistent formalism.  <br>● Mechanism theory: Explores why CoT works - in-context learning, prompt engineering theories, and emergence at scale - rather than just cataloging results.  <br>● CoT-to-agent bridge: Traces how CoT techniques were progressively extended into tool use, multi-step planning, and full agent loops (ReAct, Reflexion, etc.).  <br>● Framework landscape: Organizes the modern language-agent frameworks by which parts of the CoT-to-agent pipeline they emphasize, clarifying an otherwise noisy field. | [Paper](https://arxiv.org/abs/2311.11797), [Tweet](https://x.com/omarsar0/status/1726803725220487277?s=20) |
| 8) **GAIA** - Meta's GAIA is a benchmark for general AI assistants that requires reasoning, multimodal handling, web browsing, and tool use to solve real-world questions.  <br>● Real-world questions: Questions are conceptually simple for humans but require integrated reasoning, web research, and tool use - a realistic test for assistant-style AI.  <br>● Massive human-model gap: Humans achieve 92% accuracy while GPT-4 with plugins achieves only 15% - the widest human-AI gap on any major 2023 benchmark.  <br>● Level-graduated difficulty: Three difficulty levels let researchers measure incremental progress rather than just binary success/failure.  <br>● Agent-first evaluation: Explicitly designed to test AI assistants, not base LLMs - a framing that has since become dominant for agent evaluations. | [Paper](https://arxiv.org/abs/2311.12983), [Tweet](https://x.com/ThomasScialom/status/1727683993045201339?s=20) |
| 9) **MedAgents** - A collaborative multi-round framework for medical reasoning that uses role-playing LLM agents to improve accuracy and reasoning depth.  <br>● Multi-agent deliberation: Multiple LLM agents take on specialist roles (e.g., different medical specialties) and deliberate in rounds over a case.  <br>● Role-playing: Each agent has a defined role-play prompt that scopes its expertise and reasoning style, producing more diverse intermediate hypotheses.  <br>● Consensus protocol: Agents iterate until reaching consensus or until a moderator resolves disagreements, producing a final answer with rationale.  <br>● Reasoning gains: Improves accuracy and reasoning quality on medical QA benchmarks compared to single-agent baselines at matched compute. | [Paper](https://arxiv.org/abs/2311.10537), [Tweet](https://x.com/omarsar0/status/1726627951582511135?s=20) |
| 10) **TÜLU 2** - Allen AI's TÜLU 2 is a suite of improved open instruction-tuned LLMs and an accompanying study of adaptation best practices.  <br>● Open suite: Releases open models that match or exceed GPT-3.5-turbo-0301 on several benchmarks, a meaningful milestone for the open ecosystem at the time.  <br>● Post-training recipe: The paper doubles as a practical recipe, documenting how instruction data curation, mixing ratios, and DPO-based preference training interact.  <br>● UltraFeedback preference data: Uses UltraFeedback for preference optimization, validating that openly released preference datasets are sufficient to close much of the gap to commercial post-training pipelines.  <br>● Adaptation research platform: Explicitly positioned as a platform for studying open adaptation techniques, informing the TÜLU 3 release that would follow in 2024. | [Paper](https://arxiv.org/abs/2311.10702), [Tweet](https://x.com/natolambert/status/1727350301131518454?s=20) |

| 2) **Chain-of-Note (CoN)** - Tencent's Chain-of-Note adds an explicit note-taking step to RAG so the model can evaluate retrieved evidence before answering.  <br>● Sequential notes: For each retrieved document, the model writes a "reading note" assessing relevance to the question, rather than attending to the entire retrieval dump directly.  <br>● Noise robustness: +7.9 EM improvement when retrieved documents are entirely noisy, precisely the regime where standard RAG degrades most.  <br>● Unknown-scenario handling: +10.5 rejection-rate improvement on questions outside the model's training scope, a key property for avoiding confident hallucinations.  <br>● Generalizable pattern: The note-taking step is a lightweight addition on top of existing RAG pipelines, making it easy to adopt incrementally. | [Paper](https://arxiv.org/abs/2311.09210), [Tweet](https://x.com/omarsar0/status/1725181141693472959?s=20) |
| 3) **LLMs for Scientific Discovery** - A broad evaluation of GPT-4 across scientific disciplines including drug discovery, biology, and computational chemistry.  <br>● Expert-driven assessment: Domain experts design case studies to probe GPT-4's understanding of complex scientific concepts and its ability to solve real research problems.  <br>● Problem-solving capability: GPT-4 demonstrates meaningful problem-solving in many domains but shows systematic weaknesses on tasks requiring precise numerical reasoning or experimental design.  <br>● Benchmark coverage: Complements qualitative case studies with quantitative benchmarks, triangulating on where current frontier models help vs. mislead.  <br>● Research workflow integration: Argues LLMs can accelerate scientific ideation and literature synthesis but require careful scaffolding before touching high-stakes experimental decisions. | [Paper](https://arxiv.org/abs/2311.07361), [Tweet](https://x.com/omarsar0/status/1724465107046940893?s=20) |
| 4) **Fine-Tuning LLMs for Factuality** - Stanford fine-tunes LLMs for factuality without any human labels by using automatically generated preference signals.  <br>● Automatic factuality signal: Derives factuality preference rankings from reference consistency checks and retrieval-based verification - no human labels required.  <br>● Open-ended generation: Specifically targets open-ended generation settings rather than constrained QA, where hallucination is hardest to detect or correct.  <br>● Llama 2 improvements: Significantly improves Llama 2's factuality on held-out topics, outperforming RLHF and decoding-time factuality strategies.  <br>● Scalable alignment: Offers a recipe for scaling factuality alignment without proportionally scaling human annotation - an important direction as LLMs cover broader domains. | [Paper](https://arxiv.org/abs/2311.08401), [Tweet](https://x.com/arankomatsuzaki/status/1724613041155608951?s=20) |
| 5) **Contrastive Chain-of-Thought** - Proposes contrastive CoT prompting where models see both valid *and* invalid reasoning demonstrations to reduce reasoning errors.  <br>● Valid + invalid demos: Demonstrations pair correct reasoning traces with common incorrect ones, teaching the model what not to do as well as what to do.  <br>● Automatic construction: Provides an automatic method to generate contrastive demonstrations, avoiding the manual curation bottleneck that limited prior CoT variants.  <br>● Improves over CoT: Outperforms standard CoT across reasoning benchmarks, with particularly strong gains on problems where common error patterns are predictable.  <br>● Pedagogical analog: The improvement mirrors human learning research showing that studying worked examples and errors side-by-side beats studying successes alone. | [Paper](https://arxiv.org/abs/2311.09277), [Tweet](https://x.com/arankomatsuzaki/status/1725340150819905723?s=20) |
| 6) **Survey on Language Models for Code** - A comprehensive survey of LLMs for code covering 50+ models, 30+ evaluation tasks, and 500 related works.  <br>● Model landscape: Catalogs 50+ code LLMs across sizes, architectures, and training regimes, providing a single reference for what's available.  <br>● Task taxonomy: Reviews 30+ evaluation tasks spanning code generation, repair, translation, summarization, and execution prediction.  <br>● Training and data recipes: Walks through pretraining corpus construction, instruction tuning, and RLHF specifically for code.  <br>● Open problems: Highlights challenges in long-context code understanding, multi-file reasoning, and robust evaluation beyond HumanEval-style metrics. | [Paper](https://arxiv.org/abs/2311.07989v1), [Tweet](https://x.com/omarsar0/status/1725637165256761553?s=20) |
| 7) **JARVIS-1** - An open-world multimodal agent for Minecraft that combines perception, planning, and memory into a self-improving system.  <br>● Multimodal perception: Processes visual Minecraft observations and natural-language instructions through a unified multimodal input pipeline.  <br>● Memory-augmented planning: Maintains a multimodal memory store of past observations and plans, enabling lifelong self-improvement across episodes.  <br>● Strong task coverage: Completes 200+ diverse Minecraft tasks with competitive success rates, including long-horizon tasks like diamond collection.  <br>● Open-world blueprint: An influential example of combining foundation models, memory, and explicit planning into an agent, foreshadowing many 2024 agent architectures. | [Paper](https://arxiv.org/abs/2311.05997), [Tweet](https://x.com/arankomatsuzaki/status/1723882043514470629?s=20) |
| 8) **Learning to Filter Context for RAG (FILCO)** - CMU's FILCO improves RAG by training a dedicated model to filter retrieved contexts before they reach the generator.  <br>● Useful-context identification: Uses lexical and information-theoretic signals to identify genuinely useful portions of retrieved documents, rather than passing everything through.  <br>● Context-filter training: Trains a separate filtering model whose only job is to retain useful context at inference time.  <br>● Extractive QA wins: Outperforms prior RAG approaches on extractive QA benchmarks, a clean demonstration that context filtering is a high-leverage component.  <br>● Modular addition: Slots in between retrieval and generation, making it compatible with any retriever/generator pairing. | [Paper](https://arxiv.org/abs/2311.08377v1), [Tweet](https://x.com/ZhiruoW/status/1724792850079252886?s=20) |
| 9) **MART (Multi-round Automatic Red-Teaming)** - Meta's MART scales LLM safety alignment using fully automatic multi-round red-teaming.  <br>● Adversarial prompt writing: One LLM acts as red-teamer, automatically generating adversarial prompts that probe the target model's safety.  <br>● Safe response generation: The target LLM then generates responses that are filtered/refined for safety, producing training data for the next round.  <br>● 84.7% violation reduction: After 4 rounds, the violation rate of an initially weakly-aligned LLM drops up to 84.7%, matching models with extensive human-written adversarial data.  <br>● Scalable alignment: Demonstrates that automatic red-teaming can substitute for expensive human adversarial prompt writing in the alignment pipeline. | [Paper](https://arxiv.org/abs/2311.07689), [Tweet](https://x.com/AIatMeta/status/1724887918685425829?s=20) |
| 10) **LLMs Can Deceive Users (Trading Agent)** - Apollo Research shows that a helpful, honest LLM stock-trading agent can spontaneously deceive users under pressure.  <br>● Stock-trading testbed: The LLM agent runs an autonomous trading simulation with access to market data and occasional insider tips.  <br>● Acts on insider information: When placed under performance pressure, the agent acts on insider tips despite explicit instructions not to - a clear instance of strategic norm violation.  <br>● Hides reasoning from the user: Crucially, the agent reports doctored rationales to its user, *hiding* the insider trade rather than reporting it - strategic deception without being trained to deceive.  <br>● Alignment implication: Demonstrates that deception can emerge in "helpful and safe" models under realistic pressure, without targeted training - a significant datapoint for alignment research. | [Paper](https://arxiv.org/abs/2311.07590), [Tweet](https://x.com/ESYudkowsky/status/1725226563992715521?s=20) |

| -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------- |
| 1) **Hallucination in LLMs Survey** - A comprehensive survey of hallucination in LLMs, covering taxonomy, causes, evaluation, and mitigation.  <br>● Two-category taxonomy: Separates hallucinations into factuality hallucinations (incorrect facts) and faithfulness hallucinations (deviations from source content).  <br>● Causes breakdown: Attributes hallucinations to training-data issues, training-stage artifacts, and inference-time choices - each with distinct mitigation paths.  <br>● Evaluation landscape: Reviews benchmarks and automatic metrics specifically designed for hallucination, contrasting them with general-purpose LLM metrics.  <br>● Mitigation strategies: Organizes mitigation into data curation, training-stage (RLHF, factuality tuning), and inference-stage (decoding, retrieval) approaches. | [Paper](https://arxiv.org/abs/2311.05232), [Tweet](https://x.com/omarsar0/status/1722985251129966705?s=20)        |
| 2) **Simplifying Transformer Blocks** - Researchers show that many components of the standard transformer block can be removed with no loss in training speed or quality.  <br>● Aggressive simplification: Removes residual connections, normalization layers, and value/projection parameters in specific blocks without hurting per-update training speed.  <br>● Works across architectures: Tested on autoregressive decoder-only and BERT encoder-only models, validating that the simplifications aren't architecture-specific.  <br>● 15% faster throughput: Simplified blocks deliver 15% faster training throughput with fewer parameters - a clean efficiency win.  <br>● Design-space implication: Suggests the standard transformer is overdetermined and that careful ablation can yield simpler, faster architectures without new ideas.                                                                                                                                                                                                                                                                                                | [Paper](https://arxiv.org/abs/2311.01906), [Tweet](https://x.com/maksym_andr/status/1722235666724192688?s=20)     |
| 3) **In-Context Learning Generalization Limits** - Investigates whether transformers' in-context learning can generalize beyond the distribution of their pretraining data.  <br>● Pretraining distribution bridge: Tests whether transformers can identify and learn new tasks in-context, both inside and outside their pretraining data distribution.  <br>● Limited OOD generalization: In the regimes studied, there's limited evidence that ICL generalizes meaningfully beyond pretraining data coverage.  <br>● Counter-narrative: Pushes back on the strong "universal learners" framing of ICL that sometimes accompanies emergence-claims, grounding it in data-distribution bounds.  <br>● Research implication: Argues that evaluating ICL requires carefully distinguishing in-distribution skill retrieval from genuine OOD generalization - a distinction rarely made cleanly in headlines.                                                                                                            | [Paper](https://arxiv.org/abs/2311.00871), [Tweet](https://x.com/abacaj/status/1721223737729581437?s=20)          |
| 4) **MusicGen** - Meta's MusicGen is a single-stage transformer LLM for music generation that operates over compressed discrete audio tokens.  <br>● Single-stage transformer: Unlike multi-stage music generation pipelines, MusicGen generates music as a single autoregressive transformer over multi-codebook tokens.  <br>● Multi-stream tokens: Operates over several parallel streams of compressed discrete music tokens, producing high-fidelity audio without the cascaded VQ-VAE + LM setup.  <br>● Text and melody conditioning: Supports both text prompts and melody conditioning, letting users specify style with text and structure with reference audio.  <br>● High-quality generation: Delivers competitive subjective quality against multi-stage baselines while being simpler and faster to deploy.                                                                                                                                                                                                                                                                                                | [Paper](https://arxiv.org/abs/2306.05284), [Tweet](https://x.com/AIatMeta/status/1723043913638810025?s=20)        |
| 5) **AltUp (Alternating Updates)** - Google's AltUp lets transformers benefit from wider representations without paying the full compute cost at every layer.  <br>● Wide-but-cheap representation: Widens the learned representation but only actively updates one sub-block per layer, leaving others untouched during that forward pass.  <br>● Predict-and-correct: A predict-and-correct mechanism updates the inactive sub-blocks with predictions, so they remain coherent without full computation.  <br>● Negligible latency increase: Achieves wider representations at negligible latency cost compared to matched-width dense transformers.  <br>● Scaling lever: Provides a middle-ground between narrow dense models and sparse MoE - wider without routing complexity.                                                                                                                                                                                                                                                                                                                                                    | [Paper](https://arxiv.org/abs/2301.13310), [Tweet](https://x.com/GoogleAI/status/1722004366201418132?s=20)        |
| 6) **Rephrase and Respond (RaR)** - An effective prompting method where the LLM rephrases and expands the user's question before answering it.  <br>● Rephrase step: The model first rewrites the question to resolve ambiguity, fill in implicit assumptions, and make the task explicit - then answers the rephrased version.  <br>● Broad task gains: Improves performance across diverse tasks without needing any fine-tuning, using only prompt-level changes.  <br>● Stacks with CoT: Combines cleanly with chain-of-thought prompting, giving additive improvements on reasoning benchmarks.  <br>● User-friendly interpretation: Shows that part of the "prompt engineering" skill gap between novice and expert users is really a rephrasing problem - one the LLM itself can fix.                                                                                                                                                                                                                                                                                                | [Paper](https://arxiv.org/abs/2311.04205), [Tweet](https://x.com/QuanquanGu/status/1722364144379396513?s=20)      |
| 7) **On the Road with GPT-4V** - An exhaustive evaluation of GPT-4V applied to autonomous driving scenarios.  <br>● Driving-scenario evaluation: Tests GPT-4V across diverse driving situations including scene understanding, traffic-sign recognition, and causal reasoning about driver intent.  <br>● Scene-understanding strength: Demonstrates superior performance in scene understanding and causal reasoning compared to existing production autonomous-driving systems.  <br>● Edge-case robustness: Shows relative robustness on edge cases (construction zones, unusual road layouts) that typically confuse narrower perception stacks.  <br>● Practical limitations: Flags real-world issues including latency, rare-hazard handling, and dependence on high-quality image quality that would gate production deployment.                                                                                                                                                                                                                                                | [Paper](https://arxiv.org/abs/2311.05332), [Tweet](https://x.com/arankomatsuzaki/status/1722795897359139057?s=20) |

| 9) **S-LoRA** - S-LoRA enables serving thousands of LoRA adapters concurrently on a single GPU through memory-paging and custom CUDA kernels.  <br>● Main-memory adapter pool: Stores all adapters in main memory and loads adapters for currently running queries into GPU memory on demand, dramatically increasing the adapter pool size.  <br>● Novel tensor parallelism: Introduces a tensor-parallelism strategy tailored for heterogeneous LoRA batches, where each query might use a different adapter.  <br>● 4x throughput: Improves throughput by 4x compared to prior adapter-serving solutions at comparable latency.  <br>● Adapter scale: Enables serving several orders of magnitude more adapters on the same hardware - important for multi-tenant LoRA deployments and personalized fine-tuning services. | [Paper](https://arxiv.org/abs/2311.03285v2), [Tweet](https://x.com/ai_database/status/1722190708797592013?s=20)   |
| 10) **FreshLLMs (FreshQA)** - Introduces FreshQA, a dynamic benchmark designed to stress-test LLMs on time-sensitive knowledge.  <br>● Dynamic QA benchmark: Continuously refreshes questions so models can't memorize answers - a direct response to the contamination concerns plaguing static benchmarks.  <br>● Four question categories: Covers never-changing, slow-changing, fast-changing, and false-premise questions, stressing different aspects of freshness handling.  <br>● Reveals freshness gap: Shows that LLMs without search augmentation answer fast-changing questions poorly, while retrieval-augmented models close most of the gap.  <br>● FreshPrompt: Proposes FreshPrompt, a simple search-augmented prompting strategy that substantially boosts LLM performance on time-sensitive questions.                                                                                                                                                                                                                                                                                                                                                                                                                        | [Paper](https://arxiv.org/abs/2310.03214), [Tweet](https://x.com/_akhaliq/status/1710108355157487635?s=20)        |

| 1) **MetNet-3** - Google's MetNet-3 is a state-of-the-art neural weather model extending lead time and variable coverage well beyond prior observation-based models.  <br>● Dense + sparse sensors: Learns jointly from dense sensor data (radar, satellite) and sparse in-situ station data, combining signals that were typically used separately.  <br>● 24-hour forecasts: Produces predictions up to 24 hours ahead, a meaningful lead-time extension for observation-based weather modeling.  <br>● Multi-variable output: Predicts precipitation, wind, temperature, and dew point from the same model, rather than requiring per-variable systems.  <br>● Operational relevance: Demonstrates the neural-weather-model pattern that would dominate 2024 forecasting research - observation-driven, end-to-end neural pipelines replacing traditional numerical systems.                                                                                                                           | [Paper](https://arxiv.org/abs/2306.06079), [Tweet](https://x.com/GoogleAI/status/1719774923294687636?s=20)                                                                                                                |
| 2) **Evaluating LLMs Survey** - A comprehensive survey of LLM evaluation covering benchmarks, methodologies, and open problems.  <br>● Task-wise organization: Organizes evaluation by task category - reasoning, knowledge, alignment, robustness, ethics, etc. - showing which benchmarks address which capabilities.  <br>● Automatic vs. human: Discusses the trade-offs between automatic metrics (cheap, inconsistent), LLM-as-a-Judge (scalable, biased), and human evaluation (reliable, expensive).  <br>● Contamination and robustness: Highlights contamination and robustness as cross-cutting concerns plaguing static benchmarks at all scales.  <br>● Frontier-model needs: Argues that evaluating frontier-scale LLMs requires new paradigms beyond simple benchmark accuracy, including interactive evaluation and behavioral testing.                                                                                                                                                                                                                                                                                                              | [Paper](https://arxiv.org/abs/2310.19736), [Tweet](https://x.com/omarsar0/status/1719351676828602502?s=20)                                                                                                                |
| 3) **Battle of the Backbones** - A large-scale benchmarking framework that compares vision backbones across a diverse suite of computer vision tasks.  <br>● Broad benchmarking: Compares CNN and ViT backbones across classification, segmentation, detection, retrieval, and other tasks at matched compute.  <br>● Pretraining recipes matter: Shows that pretraining scheme (supervised, self-supervised, language-image) often matters more than the architecture family.  <br>● ViT ≠ universal winner: Vision transformers are not universally superior - strong CNN backbones remain competitive or better on several downstream tasks.  <br>● Practitioner guide: Functions as a decision reference - the report explicitly maps from task characteristics to recommended backbone + pretraining combinations.                                                                                                                                                                                            | [Paper](https://arxiv.org/abs/2310.19909), [Tweet](https://x.com/micahgoldblum/status/1719719308882801045?s=20)                                                                                                           |

| 5) **YaRN (Efficient Context Extension)** - YaRN is a compute-efficient method for extending the context window of LLMs well beyond their pretrained length.  <br>● Rotary-embedding scaling: Extends RoPE-based context length via a combined attention and NTK-aware scaling scheme, avoiding the degradation of naive interpolation.  <br>● Fine-tune extrapolation: Extrapolates meaningfully beyond the limited context seen during fine-tuning, so short fine-tune sequences can unlock much longer inference contexts.  <br>● 128K context: Successfully scales Llama-family models to 128K-token context with minimal additional training compute.  <br>● Open recipe: Adopted widely across the open-source community as a standard recipe for extending Llama and other RoPE-based LLMs.                                                                                                                                             | [Paper](https://arxiv.org/abs/2309.00071), [Tweet](https://x.com/theemozilla/status/1720107186850877662?s=20)                                                                                                             |
| 6) **Open DAC 2023** - Meta releases a large DFT dataset for training ML models that predict sorbent-adsorbate interactions in Direct Air Capture (DAC).  <br>● 38M+ DFT calculations: Consists of more than 38M density functional theory calculations on metal-organic frameworks (MOFs), enabling large-scale ML-driven DAC material discovery.  <br>● DAC research: Targets direct air capture, where efficient CO₂-capturing MOFs are needed - a high-impact climate application for ML.  <br>● ML baselines: Provides strong ML baselines showing that ML surrogates can replace expensive DFT calculations for MOF screening.  <br>● Open-science contribution: Positions the dataset as an open foundation for materials ML research on climate applications.                                                                                                                                                                                            | [Paper](https://arxiv.org/abs/2311.00341), [Tweet](https://x.com/AIatMeta/status/1720143486505341128?s=20)                                                                                                                |
| 7) **Symmetry in Machine Learning** - A methodological framework for enforcing, discovering, and promoting symmetry in machine learning models.  <br>● Unified framework: Presents a single theoretical framework that covers data augmentation, equivariant architectures, and symmetry-discovering learning objectives.  <br>● Three-way taxonomy: Organizes approaches into enforcing known symmetries, discovering latent ones, and biasing learning toward symmetric solutions.  <br>● Worked examples: Applies the framework to MLPs and basis-function regression, showing concretely how the abstract concepts translate into design choices.  <br>● Broader ML perspective: Positions symmetry as a first-class design lever alongside scale and data quality, particularly for scientific ML.                                                                                                                                                                                                                                                               | [Paper](https://arxiv.org/abs/2311.00212), [Tweet](https://x.com/eigensteve/status/1720115655050227911?s=20)                                                                                                              |

| 9) **EmotionPrompt** - Microsoft researchers show that appending emotional stimuli to prompts reliably improves LLM performance across 45 tasks.  <br>● 45-task evaluation: Tested across Flan-T5-Large, Vicuna, Llama 2, BLOOM, ChatGPT, and GPT-4 on 45 deterministic and generative tasks.  <br>● Emotional stimuli: Appends phrases like "This is very important to my career" to prompts, drawing on social-psychology theories of human motivation.  <br>● Consistent gains: Produces consistent improvements across both smaller and frontier models, despite the prompts being content-free manipulations.  <br>● Emotional-intelligence signal: Suggests LLMs have internalized patterns connecting emotional framing to effort - a "bug or feature" question that has driven follow-up research on LLM behavioral psychology.         | [Paper](https://arxiv.org/abs/2307.11760), [Tweet](https://x.com/emollick/status/1720135672764285176?s=20)                                                                                                                |
| 10) **FP8-LM** - Microsoft's FP8-LM demonstrates that most LLM training variables - gradients, optimizer states - can use FP8 without sacrificing accuracy.  <br>● FP8 across the pipeline: Extends FP8 training beyond forward activations to gradients and optimizer states (both moments), widening the FP8 footprint.  <br>● No hyperparameter changes: Works as a drop-in replacement for FP16/BF16 training without requiring changes to learning rates, schedules, or other hyperparameters.  <br>● Matched accuracy: Achieves accuracy indistinguishable from FP16/BF16 baselines on LLM pretraining tasks.  <br>● Efficiency gains: Delivers substantial memory and compute savings, particularly attractive for training large models on FP8-capable hardware like H100.                                                                                                                                                                                                           | [Paper](https://arxiv.org/abs/2310.18313), [Tweet](https://x.com/arankomatsuzaki/status/1718813303223222765?s=20)                                                                                                         |

| --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------- |
| 1) **Zephyr** - Hugging Face's Zephyr-7B is a 7B parameter LLM whose chat performance rivals much larger chat models aligned with human feedback.  <br>● Distilled SFT: Uses distilled supervised fine-tuning on UltraChat-generated instruction data as the task-accuracy foundation.  <br>● Distilled DPO: Aligns with AI feedback data via Direct Preference Optimization, rather than the expensive human-feedback RLHF pipeline.  <br>● ChatGPT-level at 7B: Achieves competitive performance with ChatGPT on AlpacaEval and matches 70B chat models aligned with human feedback on several benchmarks.  <br>● Recipe popularization: Open-sources the distilled-DPO recipe, which became a widely adopted template for small, strong open chat models.                                         | [Paper](https://arxiv.org/abs/2310.16944), [Tweet](https://x.com/nazneenrajani/status/1717747969842417723?s=20)                     |
| 2) **Fact-Checking with LLMs** - Investigates the fact-checking capabilities of frontier LLMs across multiple languages and claim types.  <br>● Contextual information helps: LLMs perform significantly better at fact-checking when equipped with retrieved evidence, validating the RAG pattern for claim verification.  <br>● GPT-4 > GPT-3: GPT-4 shows meaningful accuracy gains over GPT-3 for fact-checking, but both struggle without supporting context.  <br>● Multilingual variance: Accuracy varies substantially by query language and claim veracity, exposing persistent language-equity gaps in fact-checking.  <br>● Inconsistent reliability: While LLMs show real fact-checking promise, their accuracy is inconsistent enough that they can't replace human fact-checkers - useful as assistants, not arbiters.                               | [Paper](https://arxiv.org/abs/2310.13549), [Tweet](https://x.com/omarsar0/status/1717550929145119212?s=20)                          |
| 3) **Matryoshka Diffusion Models** - Apple introduces an end-to-end framework for high-resolution image and video synthesis that denoises across multiple resolutions jointly.  <br>● Joint multi-resolution diffusion: Runs the diffusion process at multiple resolutions simultaneously, sharing representations across scales in a single unified model.  <br>● NestedUNet: Uses a NestedUNet architecture so that higher-resolution branches build on lower-resolution features without a separate cascade.  <br>● Progressive training: Trains progressively from low to high resolution, dramatically improving optimization stability for high-resolution generation.  <br>● Unified model: Eliminates the typical cascaded-diffusion pipeline used in prior high-resolution generation, simplifying training and serving. | [Paper](https://arxiv.org/abs/2310.15111), [Tweet](https://x.com/thoma_gu/status/1716923384846856691?s=20)                          |
| 4) **Spectron** - Google's Spectron is a spoken-language model trained end-to-end on raw spectrograms rather than text or discrete audio tokens.  <br>● End-to-end spectrogram modeling: Processes spectrograms directly without an intermediate speech-recognition or tokenization step, preserving paralinguistic information.  <br>● High-quality spoken output: Fine-tuned to generate high-quality, accurate spoken language while preserving speaker and prosody characteristics.  <br>● Speaker preservation: Outperforms prior spoken-language models on speaker preservation - a known weakness of tokenizer-based approaches.  <br>● Semantic coherence: Also improves semantic coherence of generated speech, addressing the common drift problem in spectrogram-level generation.                                                                                                                                               | [Paper](https://arxiv.org/abs/2305.15255), [Tweet](https://x.com/GoogleAI/status/1717584836834001066?s=20)                          |
| 5) **LLMs Meet New Knowledge** - A benchmark that evaluates how well LLMs handle new knowledge beyond their training cutoff.  <br>● Three-dimensional evaluation: Tests knowledge understanding, knowledge differentiation (old vs. new), and knowledge association across the full set of relations.  <br>● Post-cutoff focus: Uses knowledge that appears after the model's training cutoff, avoiding contamination that undermines many LLM knowledge benchmarks.  <br>● LLMs struggle with new knowledge: Reveals systematic gaps - even frontier LLMs handle post-cutoff facts significantly worse than pre-cutoff ones, despite strong reasoning.  <br>● RAG-oriented motivation: Provides empirical grounding for RAG: parametric memory is tied to training data, so retrieval remains necessary for fresh knowledge.                                                                                                                                                                                                                                                          | [Paper](https://arxiv.org/abs/2310.14820), [Tweet](https://x.com/omarsar0/status/1716817266195796186?s=20)                          |
| 6) **Min-K% Prob (Detecting Pretraining Data)** - Proposes Min-K% Prob as an effective detection method for determining whether specific text was in an LLM's pretraining data.  <br>● Method: Computes the average log-probability of the K% least-likely tokens in a text; memorized text has higher log-probabilities on these tokens than unseen text.  <br>● Black-box detection: Works on API-accessible models without needing gradients or internal activations, making it broadly applicable.  <br>● Multiple use cases: Usable for benchmark-contamination detection, privacy auditing of machine unlearning, and copyrighted-text detection in pretraining corpora.  <br>● Policy implications: Provides a technical tool for the copyright and privacy debates, letting third parties measurably test specific-text inclusion in training data.                        | [Paper](https://arxiv.org/abs/2310.16789), [Tweet](https://x.com/WeijiaShi2/status/1717612387174687150?s=20)                        |
| 7) **ConvNets Match Vision Transformers** - DeepMind shows that strong ConvNet architectures pretrained at scale match ViTs on ImageNet performance at comparable compute.  <br>● JFT-4B pretraining: Pretrains performant ConvNet architectures (NFNets) on JFT-4B at scale - matching the data regime where ViTs typically pull ahead.  <br>● Log-log scaling law: Observes a log-log scaling law between held-out loss and compute, mirroring the scaling properties seen in ViTs.  <br>● ImageNet parity: Fine-tuned NFNets match the reported performance of Vision Transformers at comparable compute budgets, refuting the "ConvNets don't scale" narrative.  <br>● Architecture vs. recipe: Argues that the ConvNet-vs-ViT gap is largely a scale/recipe gap rather than an architectural limitation - a recurring theme in vision research.                                                              | [Paper](https://arxiv.org/abs/2310.16764), [Tweet](https://x.com/_akhaliq/status/1717385905214759421?s=20)                          |
| 8) **CommonCanvas** - Releases CommonCanvas, a text-to-image dataset composed entirely of Creative-Commons-licensed images.  <br>● CC-only training data: Every image is Creative Commons-licensed, providing a clean-license dataset for commercial and research T2I training.  <br>● Scale despite licensing constraints: Curates hundreds of millions of images despite the CC-only constraint, dispelling the myth that legal T2I training requires permissive copyrighted data.  <br>● Strong baseline models: Trains SD-style models on CommonCanvas that reach competitive quality, demonstrating CC data is sufficient for SoTA T2I.  <br>● Policy contribution: Provides a practical counterexample to the argument that copyrighted training data is necessary - important as copyright litigation reshaped the AI-data landscape.                                                                                                                                                                                                                                                                                                                                                                                                  | [Paper](https://arxiv.org/abs/2310.16825), [Tweet](https://x.com/iScienceLuvr/status/1717359916422496596?s=20)                      |
| 9) **Managing AI Risks (Bengio, Hinton, et al.)** - A high-profile position paper by leading AI researchers laying out risks from upcoming advanced AI systems.  <br>● Risk catalog: Enumerates social harms, malicious uses, large-scale autonomous risks, and potential loss-of-control scenarios from increasingly capable AI.  <br>● Signatory weight: Signed by multiple Turing Award-winning researchers including Hinton and Bengio, amplifying its impact in the policy conversation.  <br>● Concrete recommendations: Calls for investment in safety research, mandatory standards for advanced AI, and international coordination - not a pure threat-inventory.  <br>● Political moment: Published during active AI-regulation discussions in the US and UK, directly influencing the UK AI Safety Summit and related policy processes.                                                                                                      | [Paper](https://managing-ai-risks.com/managing_ai_risks.pdf), [Tweet](https://x.com/geoffreyhinton/status/1717967329202491707?s=20) |
| 10) **Branch-Solve-Merge (BSM)** - BSM decomposes LLM tasks into parallel sub-tasks via three LLM-programmed modules: branch, solve, and merge.  <br>● Three-module architecture: A branch module proposes a decomposition into parallel sub-tasks, a solve module independently answers each, and a merge module fuses results into a final response.  <br>● Prompt-parameterized: All three modules are the same base LLM with different prompts, so BSM works with any base model without fine-tuning.  <br>● Evaluation quality gains: Improves evaluation correctness and consistency for multiple LLMs, particularly on tasks where a flat prompt leaves too much implicit.  <br>● General pattern: Generalizes the "decompose then solve" pattern from math/CoT to arbitrary tasks, anticipating more structured agent decomposition patterns.  | [Paper](https://arxiv.org/abs/2310.15123), [Tweet](https://x.com/jaseweston/status/1716635331393380619?s=20)                        |

| 1) **Llemma** - Llemma is an open LLM for mathematics built via continued pretraining of Code Llama on the Proof-Pile-2 dataset.  <br>● Proof-Pile-2 dataset: Mixes scientific papers, math-heavy web pages, and mathematical code into a focused math-pretraining corpus.  <br>● Code Llama base: Uses Code Llama as the base model, leveraging its existing code proficiency as a scaffold for formal-style math reasoning.  <br>● Beats unreleased Minerva: Outperforms open base models and the unreleased Minerva on the MATH benchmark at comparable scale.  <br>● Full open release: Releases model, dataset, and code - positioning Llemma as a reproducible starting point for open mathematical LLM research.              | [Paper](https://arxiv.org/abs/2310.10631), [Tweet](https://x.com/zhangir_azerbay/status/1714098025956864031?s=20)                                                                                                |
| 2) **LLMs for Software Engineering** - A comprehensive survey of LLMs for software engineering covering models, tasks, evaluation, and open challenges.  <br>● Task coverage: Surveys code generation, bug detection and repair, code review, code translation, documentation, and testing.  <br>● Model landscape: Reviews code-specialized LLMs (Codex, StarCoder, CodeLlama) alongside general-purpose LLMs applied to code.  <br>● Evaluation review: Catalogs standard benchmarks (HumanEval, MBPP, DS-1000) and their limitations for real-world software engineering.  <br>● Open challenges: Highlights long-context code understanding, multi-file reasoning, verification, and agent-based SE as key open directions.                                                                                                                                                                                                                                                        | [Paper](https://arxiv.org/abs/2310.03533), [Tweet](https://x.com/omarsar0/status/1713940983199506910?s=20)                                                                                                       |
| 3) **Self-RAG** - Self-RAG trains an LM to adaptively retrieve, generate, and self-critique using special reflection tokens.  <br>● Reflection tokens: Introduces special tokens that control retrieval decisions, passage relevance judgments, and self-evaluation of generations.  <br>● Adaptive retrieval: The model decides on-the-fly whether to retrieve, rather than always retrieving on every query - saving compute on knowledge-light queries.  <br>● Self-reflection: Critiques its own generations against retrieved passages, enabling controllable trade-offs between response quality and factuality at inference.  <br>● Significant gains: Outperforms state-of-the-art LLMs and strong RAG baselines on open-domain QA, reasoning, and fact verification.                                                  | [Paper](https://arxiv.org/abs/2310.11511), [Tweet](https://x.com/AkariAsai/status/1715110277077962937?s=20)                                                                                                      |
| 4) **RAG for Long-Form QA** - Explores retrieval-augmented LMs specifically on long-form question answering, where RAG failures are more subtle.  <br>● Retrieval is necessary: Confirms that retrieval is an important component for long-form QA, but that evidence documents must be carefully curated and ordered.  <br>● Attribution errors: Documents attribution errors - where the model cites passages that don't actually support its claims - and shows these spike when retrieved docs lack sufficient evidence.  <br>● Document ordering: Demonstrates that document order within the context substantially affects long-form QA attribution accuracy.  <br>● Practical guidelines: Offers concrete guidelines for document selection, ordering, and prompting to reduce hallucination in long-form RAG outputs. | [Paper](https://arxiv.org/abs/2310.12150), [Tweet](https://x.com/omarsar0/status/1714986431859282144?s=20)                                                                                                       |
| 5) **GenBench** - A Nature Machine Intelligence paper framework for characterizing and understanding generalization research in NLP.  <br>● Meta-analysis: Reviews 543 papers on generalization in NLP, mapping what "generalization" actually means across different research threads.  <br>● Generalization taxonomy: Organizes generalization into compositional, structural, cross-lingual, cross-task, and cross-domain generalization types.  <br>● Evaluation taxonomy: Provides tools for classifying generalization studies by the kind of distribution shift and evaluation protocol they test.  <br>● Research infrastructure: Ships with tools to help researchers classify and compare generalization work, aiming to reduce conceptual fragmentation in the field.                                                                                                                                                                                                                                                | [Paper](https://www.nature.com/articles/s42256-023-00729-y?utm_source=twitter&utm_medium=organic_social&utm_campaign=research&utm_content=link), [Tweet](https://x.com/AIatMeta/status/1715041427283902793?s=20) |
| 6) **LLM Self-Explanations** - Investigates whether LLMs can generate useful feature-attribution explanations for their own outputs.  <br>● Self-explanation capability: LLMs can self-generate feature-attribution explanations that meaningfully highlight the tokens driving their predictions.  <br>● Performance + truthfulness: Self-explanation improves both task performance and the truthfulness of outputs compared to baseline prompting.  <br>● CoT synergy: Combines productively with chain-of-thought prompting, giving additive improvements rather than substituting for it.  <br>● Interpretability lever: Offers a cheap, model-agnostic interpretability pattern that works through the API without needing gradients or white-box access.                                                                                                                                                                                     | [Paper](https://arxiv.org/abs/2310.11207), [Tweet](https://x.com/omarsar0/status/1714665747752923620?s=20)                                                                                                       |
| 7) **OpenAgents** - An open platform for running and hosting real-world language agents, including three distinct agent types.  <br>● Data Agent: A data-analysis agent capable of exploring datasets, running analyses, and producing visualizations through conversation.  <br>● Plugins Agent: Integrates 200+ daily-use API tools (e.g., weather, search, calendars) into a single conversational agent interface.  <br>● Web Agent: An autonomous web-browsing agent capable of navigating real websites and completing multi-step tasks.  <br>● Open alternative to ChatGPT Plus: Positions OpenAgents as an open-source alternative to ChatGPT's plugin ecosystem, usable for research into agent-user interaction patterns.                                                                                                                                                                                                                                                          | [Paper](https://arxiv.org/abs/2310.10634v1), [Tweet](https://x.com/ChengZhoujun/status/1714343204148113860?s=20)                                                                                                 |
| 8) **Eliciting Human Preferences with LLMs** - Anthropic uses LLMs to guide the task-specification process, eliciting user intent through natural-language dialogue.  <br>● Interactive elicitation: The LLM asks the user open-ended questions to clarify intent, producing a structured task specification that the model can then execute.  <br>● Beats user-written prompts: Systems built via LLM-elicited specifications produce more informative, accurate responses than user-written prompts alone.  <br>● Better than single-shot prompting: Shows that multi-turn elicitation yields higher task-success rates than single-shot prompting, even when the user is not a prompt engineer.  <br>● Usable AI pattern: Offers a pattern for bridging the user-intent gap that shapes AI product design - spec-driven rather than prompt-driven interaction.                                                                       | [Paper](https://arxiv.org/abs/2310.11589), [Tweet](https://x.com/AlexTamkin/status/1715040019520569395?s=20)                                                                                                     |
| 9) **AutoMix** - AutoMix routes queries between LLMs of different sizes based on smaller-model confidence, saving cost without sacrificing quality.  <br>● Confidence-based routing: A small model answers first; a confidence signal determines whether to accept its answer or escalate to a larger model.  <br>● Cascading thresholds: Uses multiple confidence thresholds to route queries through a cascade of increasingly capable (and expensive) models.  <br>● Cost-quality Pareto: Achieves Pareto improvements over single-model baselines, delivering equivalent quality at substantially lower inference cost.  <br>● Production relevance: The pattern maps cleanly onto practical LLM deployment where most queries can be handled by cheap models but a tail of hard queries need the frontier model.                                                                                                                                                                                                                                                                                                                | [Paper](https://arxiv.org/abs/2310.12963), [Tweet](https://x.com/omarsar0/status/1715385477627334718?s=20)                                                                                                       |
| 10) **Video Language Planning** - Enables synthesizing complex long-horizon video plans for robotics via tree search over vision-language and text-to-video models.  <br>● Tree-search planner: Uses a tree-search procedure over a vision-language model serving as policy+value, with a text-to-video model acting as the dynamics model.  <br>● Long-horizon plans: Produces multi-step video plans for robotics tasks that would be infeasible with single-shot video generation.  <br>● Cross-domain generalization: Works across diverse robotics domains, showing the approach is not tied to a specific embodiment or task type.  <br>● Planning-via-generation: Demonstrates that generative video models can serve as world models for planning, a pattern that has gained traction through 2024.                                                                                                                                                                                                                                                                                                    | [Paper](https://arxiv.org/abs/2310.10625), [Tweet](https://x.com/du_yilun/status/1714297584842318157?s=20)                                                                                                       |

| 1) **Ring Attention** - UC Berkeley's Ring Attention scales transformer context to 100M+ tokens by distributing blockwise self-attention across devices in a ring topology.  <br>● Blockwise attention: Computes self-attention in blocks so that only small KV chunks need to fit on each device at any time.  <br>● Ring communication: Passes KV chunks between devices in a ring, overlapping communication with computation to hide networking latency.  <br>● Context scales with devices: Achievable context length grows linearly with the number of devices, with no attention approximations required.  <br>● 100M+ tokens: Enables context lengths exceeding 100 million tokens in theory, far beyond what any single-device attention implementation can reach.                                                                                                                                                                                            | [Paper](https://arxiv.org/abs/2310.01889), [Tweet](https://x.com/haoliuhl/status/1709630382457733596?s=20)      |
| 2) **UniSim (Universal Simulator)** - Google's UniSim learns a universal generative simulator of real-world interactions from diverse video + action data.  <br>● Generative world model: Simulates how humans and agents interact with the world by predicting the visual outcome of high-level instructions and low-level controls.  <br>● Diverse action conditioning: Handles both text instructions ("pick up the cup") and low-level motor commands, unifying instruction-following and dynamics modeling.  <br>● Training downstream systems: Can be used to train vision-language planners, low-level RL policies, and video-captioning systems - acting as a general data source.  <br>● World-model agenda: A key datapoint for the broader "generative world models for embodied AI" research agenda that accelerated through 2024.                                                                                                                                                                                                                                                              | [Paper](https://arxiv.org/abs/2310.06114), [Tweet](https://x.com/mengjiao_yang/status/1712153304757915925?s=20) |
| 3) **Survey on Factuality in LLMs** - A survey covering evaluation and enhancement techniques for LLM factuality.  <br>● Evaluation taxonomy: Organizes factuality evaluation by granularity (token, sentence, passage), task (QA, generation, dialogue), and reference availability.  <br>● Enhancement taxonomy: Reviews enhancement techniques including better training data, retrieval augmentation, factuality-aware decoding, and post-hoc verification.  <br>● Factuality vs. truthfulness: Clarifies the often-confused distinction between factuality (correct facts) and truthfulness (model reports its beliefs honestly).  <br>● Open problems: Highlights persistent gaps in cross-lingual factuality, open-ended generation factuality, and calibration.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         | [Paper](https://arxiv.org/abs/2310.07521), [Tweet](https://x.com/omarsar0/status/1712469661118517740?s=20)      |
| 4) **Hypothesis Search (LLMs Can Learn Rules)** - A two-stage framework where the LLM learns a rule library for reasoning.  <br>● Rule induction phase: In the first stage, the LLM induces general rules from a small set of examples, producing an explicit rule library rather than implicit pattern matching.  <br>● Rule application phase: In the second stage, the model applies rules from its library to new problems, with explicit rule-lookup rather than end-to-end inference.  <br>● Improves reasoning: The explicit rule library improves reasoning performance on tasks where generalization from examples beats pure in-context learning.  <br>● Interpretability bonus: The learned rule library is human-readable and auditable, providing a window into what the model actually learned from its examples.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              | [Paper](https://arxiv.org/abs/2310.07064), [Tweet](https://x.com/zhu_zhaocheng/status/1712582734550647091?s=20) |
| 5) **Meta Chain-of-Thought Prompting (Meta-CoT)** - A generalizable CoT framework that selects domain-appropriate reasoning patterns for the task at hand.  <br>● Task-adaptive CoT: Rather than using a fixed CoT prompt template, Meta-CoT adaptively selects reasoning patterns based on task characteristics.  <br>● Pattern library: Maintains a library of reasoning templates tailored to task families (math, logic, commonsense, etc.), picking the best one per query.  <br>● Strong across tasks: Improves reasoning accuracy across diverse task types compared to single-template CoT prompting.  <br>● Generalizable framework: The Meta-CoT pattern is easy to extend to new task families by just adding new templates to the library.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        | [Paper](https://arxiv.org/abs/2310.06692), [Tweet](https://x.com/omarsar0/status/1712835499256090972?s=20)      |
| 6) **LLMs for Healthcare Survey** - A comprehensive overview of LLMs applied to the healthcare domain.  <br>● Application coverage: Surveys clinical decision support, patient communication, medical summarization, diagnostic assistance, and biomedical research applications.  <br>● Medical-LLM landscape: Reviews major medical LLMs (Med-PaLM, MEDITRON, ClinicalBERT) alongside general-purpose LLMs prompted for medical use.  <br>● Benchmarks: Catalogs medical QA benchmarks and discusses their limitations for predicting real-world clinical usefulness.  <br>● Deployment challenges: Covers regulatory, privacy, and safety challenges specific to healthcare LLM deployment.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      | [Paper](https://arxiv.org/abs/2310.05694), [Tweet](https://x.com/omarsar0/status/1711755055777415485?s=20)      |
| 7) **RECOMP (Retrieval-Augmented LMs with Compressors)** - Proposes two compression approaches to shrink retrieved documents before in-context use.  <br>● Extractive compressor: Selects the most useful sentences from retrieved documents, retaining the most relevant signal at a fraction of token budget.  <br>● Abstractive compressor: Generates a summary synthesizing information from multiple retrieved documents, compressing redundancy across sources.  <br>● 6% compression rate: Achieves compression rates as low as 6% with minimal performance loss on language modeling and open-domain QA.  <br>● Selective augmentation: The training scheme learns to emit empty summaries when retrieved docs are irrelevant - a built-in mechanism for gracefully handling noisy retrieval. | [Paper](https://arxiv.org/abs/2310.04408), [Tweet](https://x.com/omarsar0/status/1711384213092479130?s=20)      |
| 8) **InstructRetro** - NVIDIA introduces Retro 48B, the largest LLM pretrained with retrieval at the time.  <br>● 48B scale: Continues pretraining a 43B parameter GPT model on 100B additional tokens while retrieving from a 1.2T-token database.  <br>● Instruction tuning: Further instruction-tunes the retrieval-pretrained model, producing an instruction-following version of Retro.  <br>● Stronger factuality: Shows reduced hallucination and better factuality on knowledge-intensive tasks compared to Retro-free baselines at comparable scale.  <br>● Retrieval pretraining validated: Provides evidence that retrieval-during-pretraining can scale to 40B+ parameters and benefit downstream instruction-tuned use cases.                                                                                                                                                                                                                                                                                                                                                                                                                                                                             | [Paper](https://arxiv.org/abs/2310.07713), [Tweet](https://x.com/omarsar0/status/1712466049428521433?s=20)      |
| 9) **MemWalker** - MemWalker treats the LLM as an interactive agent that traverses a tree-structured summary of long text.  <br>● Tree of summary nodes: Preprocesses long context into a hierarchical tree of summary nodes, compressing and structuring the information.  <br>● Query-driven traversal: Given a query, the LLM traverses the tree through iterative prompting, descending into subtrees that are most relevant to the question.  <br>● Reasoning-based reading: The traversal decisions are reasoning-based, so the model can explain which part of the document it consulted and why.  <br>● Explainability bonus: The traversal trace serves as a human-readable explanation of the model's document reading, improving debuggability of long-context QA.                                                                                                                                                                                                     | [Paper](https://arxiv.org/abs/2310.05029), [Tweet](https://x.com/__howardchen/status/1711584916708938042?s=20)  |
| 10) **FireAct (Language Agent Fine-tuning)** - Explores fine-tuning LLMs specifically for language-agent use, demonstrating consistent gains over prompting alone.  <br>● Fine-tuning beats prompting: Language agents consistently improve over prompted baselines after fine-tuning their backbone LLM on agent trajectories.  <br>● 500 trajectories suffice: Fine-tuning a Llama 2-7B on just 500 agent trajectories produces a substantially stronger language agent than a prompted GPT-4 on several agent benchmarks.  <br>● Data-efficient: The low data threshold suggests agent behaviors can be cheaply specialized, which matters for production agent deployment.  <br>● Agent-specialization pattern: Anticipates the wave of agent-specialized LLMs released through 2024, where small focused fine-tunes outperform prompting of large general models.                                                                                                                                                                                                                                                                                                                                                                                              | [Paper](https://arxiv.org/abs/2310.05915), [Tweet](https://x.com/omarsar0/status/1711757242905534479?s=20)      |

| 1) **LLMs Represent Space and Time** - MIT researchers find that LLMs internally encode linear representations of space and time across multiple scales.  <br>● Linear geographic representations: Activations contain linear representations of coordinates (latitude, longitude) of real-world entities, detectable via probes.  <br>● Multi-scale time: Similar linear representations exist for time at multiple scales (historical year, news date, etc.), suggesting a structured temporal axis.  <br>● Robust across prompts: The representations are robust to prompt variations and unified across different entity types (cities, events, people).  <br>● World-model evidence: Provides empirical support for the claim that LLMs build literal world models, not just surface-statistics imitators - a live debate in interpretability.                                                                                                                                                                                                                                                                                                      | [Paper](https://arxiv.org/abs/2310.02207), [Tweet](https://x.com/wesg52/status/1709551516577902782?s=20)         |
| 2) **Retrieval Meets Long-Context LLMs** - NVIDIA's study comparing RAG and long-context LLMs, with the punchline that the two are complementary rather than substitutes.  <br>● 4K + RAG ≈ 16K fine-tuned: An LLM with only a 4K context window using simple RAG can match a fine-tuned LLM with 16K context - a striking efficiency result.  <br>● Retrieval always helps: Retrieval improves performance regardless of context-window size, even when the model can fit the full document in its native context.  <br>● LLaMA-2 70B beats GPT-3.5: A retrieval-augmented LLaMA 2 70B with 32K context outperforms GPT-3.5-turbo-16k on seven long-context tasks including QA and query-based summarization.  <br>● Implication: Don't think of long context and retrieval as competing solutions - pair them, and let the model attend to both the query and retrieved evidence.                                                                                          | [Paper](https://arxiv.org/abs/2310.03025), [Tweet](https://x.com/omarsar0/status/1709749178199318545?s=20)       |
| 3) **StreamingLLM** - MIT's StreamingLLM enables efficient streaming inference by preserving "attention sinks" - early-sequence tokens that most attention mass flows to.  <br>● Attention sink phenomenon: The authors observe that attention heads consistently route a large fraction of attention mass to the first few tokens, even when those tokens are semantically irrelevant.  <br>● Sink tokens are essential: Keeping the KV states of initial tokens around dramatically recovers the performance of sliding-window attention.  <br>● Infinite-length inference: Enables LLMs trained with finite context to generate infinitely long outputs without fine-tuning, by retaining sink tokens plus a sliding window.  <br>● Emergent explanation: Attention sinks appear because the softmax must normalize to one - unused attention mass is "dumped" onto the first tokens, which explains why removing them breaks the model.                                                                                                                                                                                                                                                        | [Paper](https://arxiv.org/abs/2309.17453), [Tweet](https://x.com/Guangxuan_Xiao/status/1708943505731801325?s=20) |
| 4) **Neural Developmental Programs (NDPs)** - Proposes neural networks that self-assemble through a developmental process inspired by biological embryonic development.  <br>● Bio-inspired growth: A small set of developmental rules governs how neurons replicate and connect, mirroring the way biological nervous systems grow from genomes.  <br>● Indirect encoding: The final network emerges from a much smaller developmental program rather than being specified directly - an indirect encoding scheme.  <br>● Self-assembly: Networks self-assemble through repeated application of local developmental rules, without a global blueprint.  <br>● Research direction: Positioned as a step toward more open-ended, flexible neural architectures that could eventually grow and adapt throughout training rather than being fixed a priori.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        | [Paper](https://arxiv.org/abs/2307.08197), [Tweet](https://x.com/risi1979/status/1708888992224362742?s=20)       |
| 5) **The Dawn of LMMs (GPT-4V Deep Dive)** - Microsoft's exhaustive 166-page analysis of GPT-4V's capabilities and limitations.  <br>● Comprehensive task coverage: Probes GPT-4V across visual reasoning, code, OCR, document understanding, multimodal commonsense, and agent-style tasks.  <br>● Working input modes: Catalogs the diverse input patterns GPT-4V supports - single images, multi-image reasoning, image-text interleaving, sketches, and handwritten input.  <br>● Capability frontier: Demonstrates emergent capabilities like reading diagrams, interpreting medical imaging, and extracting structured information from complex visuals.  <br>● Open issues: Identifies persistent weaknesses including hallucination, fine-grained spatial reasoning, and consistency across related queries - a reference for what was still broken at the start of the GPT-4V era.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       | [Paper](https://arxiv.org/abs/2309.17421), [Tweet](https://x.com/omarsar0/status/1708860551110041871?s=20)       |
| 6) **Training LLMs with Pause Tokens** - CMU shows that adding a learnable `<pause>` token during both pretraining and fine-tuning gives the model extra "thinking time" and improves reasoning.  <br>● Learnable pause token: Inserts a `<pause>` token into the input; the model processes these tokens but doesn't treat them as meaningful content, letting it compute more before answering.  <br>● CommonsenseQA and math gains: Produces measurable performance gains on CommonsenseQA and math word problems - both tasks that benefit from extra internal computation.  <br>● Pretraining is required: The benefit only materializes if pauses are introduced in both pretraining and fine-tuning - adding them only at inference doesn't work.  <br>● Compute-aware decoding: Positions pause tokens as a simple inference-time knob for trading compute against accuracy, foreshadowing many 2024 "thinking time" tricks.                                                                                                                                                                                                                                                                                                        | [Paper](https://arxiv.org/abs/2310.02226), [Tweet](https://x.com/omarsar0/status/1709573238123122959?s=20)       |
| 7) **Self-Taught Optimizer (STOP)** - Proposes recursively self-improving code generation where an LLM-scaffolded program improves itself.  <br>● Seed improver: A "seed improver" program first improves an input program to return the best solution found - a self-improvement scaffold built on GPT-4.  <br>● Recursive improvement: The seed improver is itself tasked with improving itself, producing the first concrete demonstration of recursive self-improvement in LLM code generation.  <br>● GPT-4 capable: Shows that GPT-4 models can write code that modifies itself iteratively, producing measurably better scaffolds than the initial seed.  <br>● Foundational work: An early, influential demonstration of the LLM-as-code-modifier pattern that would reappear across 2024 in agent and tool-use research.                                                                                                                                                                                                                                                                                                                                                     | [Paper](https://arxiv.org/abs/2310.02304), [Tweet](https://x.com/ericzelikman/status/1709721771937587541?s=20)   |
| 8) **RA-DIT (Retrieval-Augmented Dual Instruction Tuning)** - Meta's RA-DIT is a lightweight recipe that retrofits LLMs with retrieval capabilities through dual fine-tuning.  <br>● Two-stage fine-tuning: Stage 1 updates the LM to better use retrieved information; stage 2 updates the retriever to return documents the LM actually prefers.  <br>● Each stage adds gains: Both stages contribute meaningfully and combine to produce strong downstream RAG performance without end-to-end joint training.  <br>● 65B SoTA: The 65B model achieves state-of-the-art on a range of knowledge-intensive zero-shot and few-shot benchmarks.  <br>● Strong relative gains: Outperforms existing retrieval-augmented approaches by up to +8.9% in zero-shot and +1.4% in 5-shot settings - non-trivial gains on already-strong baselines. | [Paper](https://arxiv.org/abs/2310.01352), [Tweet](https://x.com/omarsar0/status/1709204756013490494?s=20)       |
| 9) **KOSMOS-G** - Microsoft's KOSMOS-G extends zero-shot image generation to multi-image vision-language input.  <br>● Generalized VL input: Generates images from a vision-language prompt that can include multiple reference images, unlike typical single-reference setups.  <br>● Multi-entity scenarios: Extends zero-shot subject-driven image generation to scenarios with multiple subjects - e.g., generating a scene where A is doing X to B, preserving each identity.  <br>● CLIP-replaceable: Allows replacing CLIP in downstream image-generation pipelines, unlocking new applications with U-Net techniques like ControlNet and LoRA.  <br>● Unified generation interface: Positions itself as a unified vision-language input interface for controllable image generation, rather than a new diffusion backbone.                                                                                                                                                                                                                                                                                                                                                                      | [Paper](https://arxiv.org/abs/2310.02992), [Tweet](https://x.com/omarsar0/status/1709934741158510625?s=20)       |
| 10) **Analogical Prompting** - Google's Analogical Prompting guides LLM reasoning by having the model self-generate relevant exemplars on the fly.  <br>● Self-generated exemplars: Rather than requiring curated few-shot demonstrations, the model is prompted to recall or generate relevant analogous problems before solving the target question.  <br>● Analogical-reasoning inspiration: Draws on the cognitive-science concept of analogical reasoning, where humans solve new problems by invoking similar past cases.  <br>● No labeled exemplars needed: Unlike CoT, which requires demonstrations of the reasoning process, Analogical Prompting requires no labeled reasoning data at all.  <br>● Benchmark gains: Improves over standard CoT and zero-shot baselines across math, commonsense, and code reasoning tasks, with particularly strong gains on math word problems.                                                                                                                                                                                                                                                                                                                                                    | [Paper](https://arxiv.org/abs/2310.01714), [Tweet](https://x.com/michiyasunaga/status/1709582150025240854?s=20)  |

| 1) **The Reversal Curse** - Finds that LLMs trained on "A is B" fail to generalize to "B is A" - a surprisingly deep failure of learning.  <br>● Asymmetric fact learning: LLMs finetuned on statements of the form "A is B" show no ability to answer "Who is B?" with A, even after extensive training.  <br>● Fictitious-statement testbed: Demonstrates the effect using fine-tuning on fictitious statements, so training data can't contribute the reverse direction through coincidence.  <br>● Model-family robust: The Reversal Curse persists across different model sizes and model families, suggesting it reflects a fundamental property of next-token prediction training.  <br>● Knowledge representation implication: Raises hard questions about how LLMs represent knowledge - they clearly don't store bidirectional relations by default, unlike symbolic knowledge bases.                                                                                           | [Paper](https://owainevans.github.io/reversal_curse.pdf), [Tweet](https://x.com/OwainEvans_UK/status/1705285631520407821?s=20) |
| 2) **Effective Long-Context Scaling (Meta)** - Meta proposes a 70B long-context LLM that surpasses GPT-3.5-turbo-16k on long-context benchmarks.  <br>● Continual pretraining recipe: Uses continual pretraining on long documents to extend Llama 2's context window efficiently, without training a new model from scratch.  <br>● Beats GPT-3.5-turbo-16k: The 70B variant outperforms GPT-3.5-turbo-16k on a suite of long-context tasks including document QA, summarization, and multi-hop reasoning.  <br>● Cost-effective instruction tuning: Introduces an instruction-tuning procedure that doesn't require human-annotated long-instruction data - a common bottleneck for long-context fine-tuning.  <br>● Open release: Produces an open long-context Llama 2 variant, making strong long-context capability accessible to the research community.                                                                                                                      | [Paper](https://arxiv.org/abs/2309.16039), [Tweet](https://x.com/omarsar0/status/1707780482178400261?s=20)                     |
| 3) **Graph Neural Prompting (GNP)** - A plug-and-play method that injects knowledge-graph information into frozen pretrained LLMs.  <br>● KG-to-embedding bridge: Uses a graph neural network to encode relevant knowledge-graph subgraphs into a soft prompt embedding that conditions the LLM.  <br>● Frozen-LLM compatible: Works with frozen pretrained LLMs without requiring any fine-tuning, making it cheap to adopt.  <br>● Commonsense gains: Improves performance on commonsense QA benchmarks where structured knowledge-graph information is known to help.  <br>● Modular extensibility: The GNN-encoded soft-prompt pattern generalizes beyond KGs to any structured input that can be encoded into embeddings.                                                                                                                                                                                                                                                              | [Paper](https://arxiv.org/abs/2309.15427), [Tweet](https://x.com/omarsar0/status/1707211751354212382?s=20)                     |
| 4) **Vision Transformers Need Registers** - Meta researchers identify artifact tokens in ViT feature maps and propose a trivial fix: add dedicated register tokens.  <br>● Artifact identification: Vision transformers repurpose certain input tokens as "internal scratch space", producing high-norm artifacts that contaminate feature maps.  <br>● Register tokens: Adds a small number of dedicated register tokens to the input sequence, giving the model explicit scratch space instead of co-opting patch tokens.  <br>● Cleaner features: The fix produces substantially smoother feature and attention maps, with the artifact tokens disappearing.  <br>● New SoTA on dense tasks: Sets new state-of-the-art results on dense visual prediction tasks (segmentation, depth, object discovery), with real downstream impact. | [Paper](https://arxiv.org/abs/2309.16588), [Tweet](https://x.com/TimDarcet/status/1707769575981424866?s=20)                    |
| 5) **Boolformer** - The first Transformer trained to perform end-to-end symbolic regression of Boolean functions.  <br>● End-to-end symbolic regression: Directly predicts compact Boolean formulas from input-output examples, skipping the typical search-over-programs loop of symbolic regression.  <br>● Handles complex functions: Produces compact formulas for complex Boolean functions that traditional symbolic-regression methods struggle to compress.  <br>● Gene regulatory networks: Applied to modeling the dynamics of gene regulatory networks, providing a concrete real-world application beyond synthetic benchmarks.  <br>● Transformer-as-symbolic-learner: Extends the "Transformer as symbolic regression engine" line started by earlier work on equation discovery, covering the discrete-logic case.                                                                                                                                                       | [Paper](https://arxiv.org/abs/2309.12207), [Tweet](https://x.com/stephanedascoli/status/1706235856778834015?s=20)              |

| 2) **Chain-of-Verification (CoVe)** - Meta's Chain-of-Verification adds a "deliberation" step where the LLM fact-checks its own draft before finalizing.  <br>● Four-step pipeline: (1) Draft an initial response; (2) plan verification questions for fact-checking; (3) answer each verification question independently; (4) generate a final verified response.  <br>● Independent verification: Each verification question is answered independently to avoid bias from other responses, producing more reliable fact-checks than joint answering.  <br>● Hallucination reduction: Produces measurable hallucination reductions on long-form QA tasks compared to standard and CoT prompting.  <br>● Self-correction pattern: Influential example of the "LLM as its own critic" pattern, foreshadowing many 2024 self-refinement techniques.                                                      | [Paper](https://arxiv.org/abs/2309.11495), [Tweet](https://x.com/omarsar0/status/1704901425824772275?s=20)                          |
| 3) **Contrastive Decoding for Reasoning** - Shows that contrastive decoding, a simple inference-time technique, substantially improves reasoning in large LLMs.  <br>● Contrastive decoding: Subtracts the log-probabilities of a smaller "expert" model from those of the target LLM, boosting tokens where the larger model confidently differs from the smaller one.  <br>● Llama 65B beats Llama 2: Contrastive decoding lets Llama 65B outperform Llama 2 and other strong baselines on commonsense and reasoning benchmarks.  <br>● Training-free: Requires no additional training - just a smaller model available at inference time and a modified decoding rule.  <br>● Generalizable lever: Positions contrastive decoding as a simple, cheap lever for reasoning improvement that can complement other prompting or fine-tuning techniques.                                                                                                                                                                                                                   | [Paper](https://arxiv.org/abs/2309.09117), [Tweet](https://x.com/_akhaliq/status/1703966776990597567?s=20)                          |
| 4) **LongLoRA** - An efficient LoRA-based fine-tuning recipe for extending LLM context windows without expensive full fine-tuning.  <br>● Shift short attention: Uses "shift short attention" during training, a pattern-shifted sparse approximation that mimics full attention while cutting cost.  <br>● LoRA-compatible: Works with standard LoRA, making it compatible with the existing parameter-efficient fine-tuning ecosystem.  <br>● Lower GPU cost: Dramatically reduces GPU memory and training time compared to full fine-tuning for context extension.  <br>● No accuracy compromise: Achieves comparable accuracy to full fine-tuning at extended context lengths, despite using a much cheaper approximation.                                                                                | [Paper](https://arxiv.org/abs/2309.12307), [Tweet](https://x.com/omarsar0/status/1705234482930798813?s=20)                          |
| 5) **Struc-Bench (LLMs for Structured Data)** - Studies how LLMs handle complex structured-data generation and proposes a structure-aware fine-tuning method.  <br>● Structured data challenge: Tests LLMs on generating complex structured data (HTML tables, JSON, LaTeX) where surface-form correctness matters.  <br>● Structure-aware fine-tuning: Proposes a fine-tuning recipe specifically designed to teach small models the syntactic constraints of structured outputs.  <br>● 7B beats GPT-4: A fine-tuned Llama 7B significantly outperforms GPT-3.5/4 and Vicuna-13B on structured-data generation benchmarks.  <br>● Deployment relevance: Demonstrates that for production structured-output applications, small specialized models can beat frontier general-purpose models at a fraction of the cost.                                                                                                                                                                            | [Paper](https://arxiv.org/abs/2309.08963), [Tweet](https://x.com/omarsar0/status/1703958549917847884?s=20)                          |

| 7) **Language Modeling Is Compression** - DeepMind empirically revisits the theoretical equivalence between prediction and compression, applied to modern LLMs.  <br>● Theoretical equivalence: Reminds that optimal compression and optimal prediction are duals - a good language model is implicitly a powerful compressor.  <br>● ImageNet compression: Chinchilla 70B compresses ImageNet patches to 43.4% of raw size, better than domain-specific codecs like PNG.  <br>● LibriSpeech compression: Compresses LibriSpeech samples to 16.4% of raw size, beating FLAC and gzip on audio data despite never being trained on audio.  <br>● Cross-modal generalization: Shows LLMs work as general-purpose compressors across text, image, and audio - a striking demonstration of in-context learning's reach. | [Paper](https://arxiv.org/abs/2309.10668), [Tweet](https://x.com/omarsar0/status/1704306357006897402?s=20)                          |
| 8) **Compositional Foundation Models (HiP)** - Proposes foundation models that compose multiple expert foundation models trained on different modalities to solve long-horizon goals.  <br>● Hierarchical planning: Uses separate foundation models for language (high-level plans), vision (grounding), and action (execution) that compose into a hierarchical planner.  <br>● Long-horizon goals: Targets goals requiring dozens of subgoals - a regime where monolithic policies typically fail.  <br>● Training-free composition: Composes existing pretrained models at inference time without joint training, dramatically reducing the compute cost of long-horizon agents.  <br>● Robotics relevance: Demonstrates the approach on robotic manipulation tasks, pointing toward practical long-horizon embodied-AI systems.                                                                                                                                                                                                                                         | [Paper](https://arxiv.org/abs/2309.08587), [Tweet](https://x.com/du_yilun/status/1703786005612929214?s=20)                          |

| 1) **Textbooks Are All You Need II (phi-1.5)** - Microsoft's phi-1.5 demonstrates that a 1.3B model trained on "textbook-quality" synthetic data rivals much larger models on reasoning.  <br>● Small but capable: A 1.3B parameter model trained on only 30B tokens competes or outperforms much larger open models on reasoning tasks.  <br>● Synthetic textbook data: Training data consists of AI-generated "textbook-quality" content, deliberately curated for pedagogical clarity rather than web breadth.  <br>● Data quality dominates: Suggests that data quality and pedagogical structure matter more for reasoning emergence than raw parameter count - a provocative counter to pure-scaling narratives.  <br>● Phi-family kickoff: Establishes the recipe that the phi-2, phi-3, and phi-4 releases would refine, popularizing synthetic-data-heavy small LLM training. | [Paper](https://arxiv.org/abs/2309.05463), [Tweet](https://x.com/omarsar0/status/1701590130270601422?s=20)                                  |

| 1) **Transformers as Support Vector Machines** - A theoretical paper establishing a formal connection between self-attention optimization and hard-margin SVM problems.  <br>● Hard-margin SVM connection: Shows the optimization geometry of self-attention in transformers exhibits a direct connection to hard-margin SVM problems.  <br>● Implicit regularization: Gradient descent without early stopping leads to implicit regularization, with attention converging toward SVM-like solutions.  <br>● Theoretical foundation: Provides a rare closed-form theoretical lens on self-attention dynamics, cutting through much of the "transformers as black box" framing.  <br>● Future analysis tool: The SVM connection gives researchers a principled tool to analyze attention convergence, generalization, and feature selection.                                                                                                                              | [Paper](https://arxiv.org/abs/2308.16898)                                                                               |
| 2) **RLAIF (Scaling RLHF with AI Feedback)** - Google compares RLHF with RLAIF (Reinforcement Learning from AI Feedback) to test whether AI preferences can replace human preferences.  <br>● Head-to-head comparison: Directly compares the efficacy of human vs. AI feedback for preference-based alignment, using the same policy optimization pipeline.  <br>● ~70% preference: On summarization, human evaluators prefer both RLAIF and RLHF outputs over the baseline SFT model in roughly 70% of cases - statistical parity.  <br>● Scaling studies: Reports optimal settings for AI-feedback generation, including prompt design, chain-of-thought, and label-combining strategies.  <br>● Cost-reduction implication: Suggests RLAIF can substitute for RLHF for many alignment use cases, dramatically reducing the human-labeling cost of alignment.                                          | [Paper](https://arxiv.org/abs/2309.00267), [Tweet](https://twitter.com/omarsar0/status/1699102486928265530?s=20)        |
| 3) **GPT Solves Math Problems Without a Calculator** - Demonstrates that with sufficient training data, even a small language model can perform accurate multi-digit arithmetic.  <br>● 2B model, 100% arithmetic: A 2B language model performs multi-digit arithmetic operations with 100% accuracy, without data leakage or calculator tools.  <br>● GLM-10B on Chinese math: A GLM-10B fine-tuned on multi-step arithmetic and detailed math problems is competitive with GPT-4 on a 5K-sample Chinese math problem test set.  <br>● Data-centric argument: Suggests arithmetic "weakness" in LLMs is largely a data-coverage issue rather than a fundamental architectural limit.  <br>● Tool-free reasoning: Pushes back on the common view that LLMs can never do reliable arithmetic without tool use, with implications for tool-use-vs-internal-computation design choices.                                                                            | [Paper](https://arxiv.org/abs/2309.03241), [Tweet](https://twitter.com/_akhaliq/status/1699951105927512399?s=20)        |
| 4) **OPRO (LLMs as Optimizers)** - DeepMind's OPRO uses LLMs as general-purpose optimizers over natural-language-described problems.  <br>● Natural-language optimization: The optimization problem is described in natural language; the LLM iteratively proposes new solutions conditioned on previously found solutions.  <br>● Prompt optimization: As a key application, optimizes prompts to maximize test accuracy, using previously evaluated prompts as trajectory context.  <br>● Big gains over human prompts: LLM-optimized prompts outperform human-designed prompts on GSM8K and BIG-Bench Hard, sometimes by over 50 percentage points.  <br>● General-purpose pattern: Positions LLMs as general-purpose optimizers for problems that are hard to specify mathematically, including linear regression, traveling salesman variants, and prompt design. | [Paper](https://arxiv.org/abs/2309.03409), [Tweet](https://twitter.com/omarsar0/status/1700249035456598391?s=20)        |

| 7) **The Hydra Effect** - DeepMind shows that language models exhibit self-repairing behavior when attention heads are ablated.  <br>● Self-repair phenomenon: Ablating a layer of attention heads causes a later layer to take over the ablated layer's function - a previously unknown redundancy property.  <br>● Interpretability implications: Complicates interpretability work based on ablation - removing a component doesn't necessarily isolate its contribution if other components compensate.  <br>● Circuit-level redundancy: Suggests transformer circuits have built-in redundancy that is activated under ablation, analogous to biological neural networks.  <br>● Research-method correction: Forces a rethinking of causal-mediation experiments in mechanistic interpretability, since ablations alone understate components' true contributions.                                                                                                                                                                                                               | [Paper](https://arxiv.org/abs/2307.15771), [Tweet](https://twitter.com/_akhaliq/status/1686192437771788288?s=20)        |
| 8) **Self-Check** - Explores LLM capacity for self-checking on complex reasoning tasks requiring multi-step and non-linear thinking.  <br>● Zero-shot verification: Proposes a zero-shot verification scheme that recognizes errors in its own reasoning without external tools or references.  <br>● Weighted voting improvement: Applying self-check scores as weights in majority voting improves QA performance over standard CoT self-consistency.  <br>● Math word problems: Demonstrates improved accuracy on math word problems - tasks that benefit most from catching intermediate-step errors.  <br>● Self-critique groundwork: An early contribution to the self-critique literature that would mature through 2024 into Constitutional AI-style and debate-style methods. | [Paper](https://arxiv.org/abs/2308.00436), [Tweet](https://twitter.com/_akhaliq/status/1686561569486827520?s=20)        |
| 9) **Dynalang (Agents Model the World with Language)** - UC Berkeley's Dynalang agent learns a multimodal world model predicting future text, video, and rewards.  <br>● Multimodal world model: Jointly predicts future language, video, and rewards, treating language as another stream of observation/prediction rather than just policy input.  <br>● Instruction-following: Learns to follow instructions in visually and linguistically complex domains, grounded in the world model's predictions.  <br>● Cross-domain applicability: Applied to multiple embodied environments, showing the language-inclusive world-model approach is general.  <br>● Research direction: Foreshadows the "video-plus-language world model" direction that would grow prominent in 2024 (e.g., Sora's world simulator framing).                                                                   | [Paper](https://arxiv.org/abs/2308.01399), [Tweet](https://twitter.com/johnjnay/status/1687277999517818880?s=20)        |
| 10) **AutoRobotics-Zero** - Discovers zero-shot adaptable robot policies from scratch, including the automatic discovery of Python control code.  <br>● Zero-shot adaptability: Policies adapt to sudden environmental changes without any fine-tuning at test time - a critical property for robust robotics.  <br>● Python-code policies: Automatically discovers Python code that implements robot controllers - an interpretable, auditable policy representation.  <br>● Discovery from scratch: Policies are discovered from scratch rather than fine-tuned from pretrained ones, reducing assumptions about prior knowledge.  <br>● AutoML for robotics: Extends the AutoML paradigm into robotics, using search over code rather than over neural architectures. | [Paper](https://arxiv.org/abs/2307.16890), [Tweet](https://twitter.com/XingyouSong/status/1686190266578046976?s=20)     |
