GPT-4 hallucinates significantly less than those other models but it is going way too far to say that it has fixed the issue completely. In my experience, it probably hallucinates about 3x less than GPT 3.5. I use GPT-4 a lot but really only for code generation and answering questions about documentation. I'm not including cases where it gives answers that are out of date as hallucations, I consider that an entirely separate failure mode.
