All I'm saying is that determinism has a specific meaning in computer science. In an LLM, the rng value is determined by the seed. Given the same inputs, an LLM always produces the same output. It does not matter whether the user understands the code or operation at all. It is purely dependent on the program itself.

A non-deterministic program, is one where the output is determined by factors outside the code itself. This usually requires non-deterministic programming language constructs. For example, if you convert a set to a list in python, the order of the elements is non-deterministic. Out of the control of the program. Same inputs, different output.
