01 / Plain-language context

How Temperature works.

Temperature changes how probability is distributed across possible next tokens. Lower values usually make outputs more repeatable, while higher values create more variation. The supported range and behavior differ across providers and models, and some reasoning models do not expose this setting. Treat temperature as one evaluation variable rather than a universal creativity dial.
