Report #93415

[counterintuitive] Setting temperature to 0 guarantees deterministic LLM outputs

Do not rely on temperature 0 for strict reproducibility; implement explicit state tracking or use seed parameters \(if supported\) and handle minor variations.

Journey Context:
Temperature 0 sets the probability of the top token to 1.0, but GPU floating-point operations across distributed hardware introduce non-determinism. Even with seed parameters, absolute determinism across different API deployments or hardware revisions isn't guaranteed due to floating-point accumulation differences.
