I see LLM inference as sampling from a distribution. Multiple details go into that sampling - everything from parameters like temperature to numerical imprecision to batch mixing effects as well as the next-token-selection approach (always pick max, sample from the posterior distribution, etc). But ultimately, if it was truly important to get stable outputs, everything I listed above can be engineered (temp=0, very good numerical control, not batching, and always picking the max probability next token).

dekhn from a decade ago cared a lot about stable outputs. dekhn today thinks sampling from a distribution is a far more practical approach for nearly all use cases. I could see it mattering when the false negative rate of a medical diagnostic exceeded a reasonable threshold.

Errr... that word implies some type of non-deterministic effect. Like using a randomizer without specifying the seed (ie. sampling from a distribution). I mean, stuff like NFAs (non-deterministic finite automata) isn't magic.

Interesting, but in general it does not imply that. For example: https://en.wikipedia.org/wiki/Nondeterministic_finite_automa...

I agree its phrased poorly.

Better said would be: LLM's are designed to act as if they were non-deterministic.
