It's ok for small blocks or code, maybe a function or two, even a whole class, but beyond that, it's pretty pathetic. Even the small blocks of code it outputs only compile a few times and have a few errors. At this point, I would be wary of using it in Production systems.

Having said that, I usually compare it with Junior programmers, more like someone just learning a new programming language. You can expect that level of performance from ChatGPT!
