Concept

Temperature

Sampling parameter that controls randomness — lower is more deterministic, higher more creative.

Definition

Temperature divides logits before the softmax. Temperature 0 collapses to greedy decoding; values >1 flatten the distribution, increasing diversity (and incoherence). Typical chat defaults are 0.6–0.8. It is the single most impactful sampling knob.

Common use cases

  • Creative writing
  • Deterministic tests
  • Brainstorming
