Why double user provided temperature?

[natrys]

Hi, thanks for the package. Can I ask though, why do we double the user provided temperature value here?

llm/llm-openai.el

Line 218 in 9e754cd

(push `("temperature" . ,(* (llm-chat-prompt-temperature prompt) 2.0)) request-alist))

Different providers have different scales for temperature. OpenAI has a 0 to 2 scale, others have a 0 - 1 scale, and I prefer 0-1. This scale is documented in the docstring for llm-make-chat-prompt. So, to account for the differences in scales, we double the temperature here.

Oh right, that makes total sense.
