Similar experience. I recently needed to turn a list of files into a certain tree structure. It is a non-trivial problem with a little bit of flavor of algorithm. I was wondering if GPT can save me some time there. No. It never gave me the correct code. I tried different prompts and even used different models (including the latest GPT 4 Turbo), none of the answers were correct, even after follow-ups. By then I already wasted 20 minutes of time.

I ended up implementing the thing myself.
