I don’t have great experiences trying to get LLMs to write code, but I’ve found it to be incredibly valuable for checking my code for mistakes and oversights. Sure, it will spit out nit picks, false positives, and straight up nonsense, but at a rate that is quite a bit lower than other tools I’ve used. I not infrequently end up going through a number of iterations, rewriting code and tests based on its feedback, until I’m happy with the code and the LLM no longer points out actual problems.

It probably doesn’t help my productivity, in terms of lines of code committed or whatever companies might use, but it certainly helps improve the quality of my work
