            "LLAMA-2-70B + So, if you imagine a black hole as a super-powerful vacuum cleaner, it can suck up anything that gets too close. And because it's so small, it can fit in lots of different places, like in the middle of a galaxy or even in space all by itself\n",
            "LLAMA-2-13B - Assistant: Well, black holes are formed when a star dies and collapses in on itself. The star's gravity gets so strong that it warps the fabric of space and time around it, creating a boundary called the event horizon. Once something crosses the event horizon, it's trapped forever.\n",
