Comment by diffeomorphism

The problem is that the models hallucinate too confidently. In this case it is quite amusing (I had llama3.1:8b tell me confidently it is 1, then revise to 2, then apologize again and give the correct answer). However, while it is obvious here, having it confidently make up supposed software features from thin air when asking for "how do I ..." is more problematic. The answers sound plausible, so you actually waste time verifying whether they work or are nonsense.
