You think you are “nailing it” but also lack the background to even determine whether that is the case. I can assure you, there’s likely some fundamental flaws in what you’re vibing.
Just think about the type of code these things are trained on and the fact you’re clearly some random non-specialist.
> some fundamental flaws in what you’re vibing
That's just a misunderstanding, I'm not "vibing" anything. The tests are written by me, the API interfaces are written by me, the usages are written by me, and the implementation of these functions are written by an LLM, but reviewed to be up to code standards/quality by me.
If a function gives me the right output for the inputs I have in mind, does anything beyond that really matter?
