The temperature parameters largely went away when we moved towards reasoning models, which output lots of reasoning tokens before you get to the actual output tokens. I don’t know if it was found that reasoning works better with a higher temperature, or that having separate temperatures for reasoning vs. output wasn’t practical, but that’s my observation of the timing, anyway. And to the other commenter’s point, even a temperature of 0 is not deterministic if the batches are not invariant, which they’re not in production workloads.
