What Is AI Model Temperature?
Temperature is a parameter in AI language models that controls the randomness of the output — lower temperature values (e.g., 0.1) produce more deterministic, focused responses, while higher values (e.g., 1.0) produce more creative, varied, and sometimes unpredictable outputs.
How AI Model Temperature Works
When an AI model generates text, it calculates a probability for each possible next word (token). Temperature adjusts how these probabilities are distributed before the model makes its selection. At temperature 0, the model always picks the most probable token, producing highly consistent but potentially repetitive responses. At higher temperatures, the probability distribution flattens, giving less likely tokens a better chance of being selected, which introduces creativity and variety. A temperature of 0.7 is a common default that balances coherence with creativity. For factual tasks like summarization or data extraction, low temperatures work best. For brainstorming, creative writing, or generating diverse ideas, higher temperatures are more effective.
Real-World Examples
Setting temperature to 0.2 for a customer support bot to ensure consistent, accurate responses
Using temperature 0.9 for a creative writing assistant to generate more imaginative story ideas
A developer setting temperature to 0 for code generation to get the most reliable, predictable outputs
