I understand how they work, as I do work with them everyday and been doing so for two years or so. What I don't understand, is how what you're saying is in any way related to the whole "deliberately create errors in code" part, which is where I jumped into the discussion.

Maybe I'm missing some bigger picture you're trying to paint here? I understand (and see) them making "mistakes" all the time, and I guess you could argue it's deliberate in some way, because it's simply how they work and adjusting the prompt and redoing usually solves the problem. But I'm afraid I don't see how it's connected, at least yet.
