I think you can trust the code of both those worlds exactly the same, not at all.
I’ve seen GPT 3 and 4 hallucinate the most amazing commentary about their own output. Maybe we will get dependable, out of process, guidance at some point about how factual the model thinks it is on an output per output basis but until that point you should trust every LOC and comment exactly the same as code gifted to you by an adversary.
My modest 2¢
Exactly... and then the question becomes: why do I interact with an adversary?
You mean, like almost every outsourcing company pops over? So the type of code that infests companies who hired some sweatshop to do ‘some simple crud’? What’s the difference? Can you see the difference? Besides the gpt code will be far better commented as comments come for almost free with gpt while humans hate writing them.
