Nope, not my experience - unless it's a trivial problem. In my experience it almost always gets stuck in a loop where it's rotating between two or more incorrect implementations. It isn't doing iteration - it's just looping. Even if I point out the problem directly, it will just say "sorry, you're right - here's the correction!" and the correction has the same response from an earlier item that I pointed out had a problem!

Used to get that a lot with GPT-3.5. But GPT-4 has been more reliable if you rephrase your prompt.

Have not had that experience with GPT-4. But that is almost unusable for me anyway because it's crazy slow (during US working hours anyway, it's faster at night) and the rate caps get hit before we get anywhere.
