Wow, it's way smarter. I've been querying GPT-3 about this problem all day (I'm not a go dev, I just have go problems):

GPT-4 took the buggy file, took the error message, and spat out a non-buggy file (well, ok, it took one revision). That's miles ahead GPT-3, which I've asked about this problem several times today.
