Temperature
The AI setting that controls how creative (high) or predictable (low) responses are.
Also known as: temperature setting
Temperature is a setting that controls how creative versus how predictable an AI's responses are. Temperature is a number, typically between 0 and 2. Low temperature (0.0–0.3) makes the model deterministic — same input, same output, always picks the highest-probability next word. High temperature (0.7–1.5) makes it creative and varied — willing to pick less likely words, more surprising responses. Use low temperature for: code generation, factual extraction, format-strict tasks. Use high temperature for: creative writing, brainstorming, marketing copy. ChatGPT defaults to around 0.7 for chat. Most users never change it; developers using the API tune it carefully.
