Thanks a lot for this. Also one question in case anyone could shed a bit of light: my understanding is that setting temperature=0, top_p=1 would cause deterministic output (identical output given identical input). For sure it won’t prevent factually wrong replies/hallucination, only maintains generation consistency (eq. classification tasks). Is this universally correct or is it dependent on model used? (or downright wrong understanding of course?)
- antonvs 10mo ago> my understanding is that setting temperature=0, top_p=1 would cause deterministic output (identical output given identical input). That's typically correct. Many models are implemented this way deliberately. I believe it's true of most or all of the major models. > Is this universally correct or is it dependent on model used? There are implementation details that lead to uncontrollable non-determinism if they're not prevented within the model implementation. See e.g. the Pytorch docs for CUDA convolution determinism: https://docs.pytorch.org/docs/stable/notes/randomness.html#cuda-convolution-determinism https://docs.pytorch.org/docs/stable/notes/randomness.html#c... That documents settings like this: torch.backends.cudnn.deterministic = True Parallelism can be a source of non-determinism if it's not controlled for, either implicitly via e.g. dependencies or explicitly.
