They nerfed it at Dev Day in November. It’s just no longer the magic tool it was before than anymore. It’s ok for maybe one shot problems or refactors of small functions but the version where you could in an hour work back and forth with it and build something moderately complex from scratch is dead and often some of the generations just waste time rather than solve the problem.
I don't know that I'd say they nerfed it exactly. They made some tradeoffs you don't like. The old GPT4 had more personality, was more flexible in its responses and would go on for longer. The new GPT4 is more consistently helpful and does a better job of presenting small-form answers neatly, but the alignment has definitely had an impact for a lot of use cases.
