@nprofile1q... now, I suspect people started calling this hallucination because some of the original examples seemed to just pull something from thin air, and besides, it makes the LLM sound silly. The reality is, the LLM is Making Shit Up. This MSU problem is an unfixable disaster. Imagine trying to read a two page story about someone else’s day, and find the one line in 100 (which is about the rate) that is just made up shit. How much concentration does that take?
