I've lost track of the number of times Claude has basically said "it was like that when i got here" in the face of a clearly bogus choice and easily disproved explanation.
I pointed out that updoc is nonsense and asked why it didn't catch that. The answer was that it was my fault for giving it bad info.
While the "stochastic parrots" thing is a bit overblown, IME most LLMs tend to surprisingly different responses even without changing the context, especially if they're hallucinating or doing something "wrong".
