Unrelated to the gp post, but isn't LLMs more like a deterministic chaotic system than a "non-deterministic" one? "Tiny changes to the input can change the output quite a lot" is similar to "extreme sensitivity to initial condition" property of a chaotic system.

I guess that could be a problematic behavior if you want reproducibility ala (relatively) reproducible abstraction like compilers. With LLMs, there are too many uncontrollable variables to precisely reproduce a result from the same input.
