This is one of the reasons i never used LLMs for anything related to coding. And i never intend to do. If i tell the thing to generate, will it generate the same thing, every time? will it change stuff that is working because the random number generator will conjure a slightly different answer?
i'd be ok with it if i was generating a picture of X, or some word salad about Y, but not for code. Never for code.
You'll learn to work around it, just like ML practitioners got used to imprecise math in regards to floats. But that LLMs are using imprecise math and doesn't have 100% reproducible output doesn't make them impossible to work with, just a bit harder.
But, if what you're doing right now works for you, do continue as-is if you so wish, I have no stake in if people use LLMs or not, just hope people make choices based on good information :)
