Temperature

How models work Last reviewed 2026-06-11

Definition A setting that controls how predictable or varied an AI model's output is. Low temperature makes responses more consistent and conservative; high temperature makes them more varied and creative.

In more depth

Technically, temperature reshapes the probability distribution the model samples from when choosing each next token. At low settings the model nearly always picks the most likely continuation, which suits drafting and analysis; higher settings encourage variety, which suits brainstorming. Temperature affects variability, not truthfulness—a model at the lowest setting can still hallucinate.
