If I understand your argument, you're saying that models can be deterministic, right?

Care to point to any that are set up to be deterministic?

Did you ever stop to think about why no one can get any use out of a model with temp set to zero?

llama.cpp is deterministic when run with a specified PRNG seed, at least when running on CPU without caching. This is true regardless of temperature. But when people say "non-deterministic", they really mean something closer to "chaotic", i.e. the output can vary greatly with small changes to input, and there is no reliable way to predict when this will happen without running the full calculation. This is very different behavior from traditional compilers.

No, LLMs ARE deterministic, just like all computer programs are.

I get why that is in practice different then the manner in which compilers are deterministic, but my point is the difference isnt because of determinism.

I think you are misunderstanding the term "deterministic". Running on deterministic hardware does not mean an algorithm is deterministic.

Create a program that reads from /dev/random (not urandom). It's not determistic.

Fair, although you can absolutely use local LLMs in a deterministic way (by using fixed seeds for the random number generation), and my point is that even if you did that with your LLM, it wouldn't change the feeling someone has about not being able to reason out what was happening.

In other words, it isn't the random number part of LLMs that make them seem like a black box and unpredictable, but rather the complexity of the underlying model. Even if you ran it in a deterministic way, I don't think people would suddenly feel more confident about the outputted code.
