| ▲ | azakai 14 hours ago | parent [-] | | The hardware can also add nondeterminism. GPUs reorder operations, leading to different results. Vendors might also be running A/B testing or who knows what, even when you ask for a temperature of 0. But, if you run a fixed model with temperature 0 on your local CPU, it will be deterministic (unless there are bugs). |

| ▲ | bcjdjsndon 17 hours ago | parent [-] | | They're next word predictors. They explicitly add in randomness at various stages of the transformer itself, otherwise it'd be too obvious it's not actually intelligent and just a next word predictor | | |
