I think it is still pretty decent at "coding", but it used that I could throw almost anything at it about virtually anything and most of the time there was no hallucinations if the prompt was good. It has always been prone to beong influenced by biased prompts so you had.to work around that.

Lately I feel like I really need to draw out answers out of it. You have to insist to get past the cookie-cutter reponses and all the newly added "I am not a specialist therefore I refuse to answer". Historical questions are often refused too if deemed offensives. But really, its been unable to give me all sort of general facts like it used too by lying about the cutoff date of 2021, even after being corrected and apologizing. Some answers are purely 100% hallucinations. Its never been perfect but it used to be better than googling, well not anymore imo. It is still probably decent for non-historical questions, like coding.
