LLMs are deterministic at minimal temperature. Talking about determinism completely misses the point. The human brain is also non-deterministic and I don't see anybody dismiss human written code based on that. If you remove randomness and choose tokens deterministically, that doesn't magically solve the problems of LLMs.

Humans, in all their non deterministic brain glory, long ago realized they don't want their software to behave like their coworkers after a couple of margaritas.
