LLM temperature: not creativity, but probability distribution control

By PulseAugur Editorial · [1 sources] ·

The LLM temperature parameter is often misunderstood as a creativity dial, but it actually controls how the model's probability distribution is reshaped before sampling the next token. A temperature of 1.0 uses the distribution as-is, while lower temperatures sharpen the distribution by favoring more probable tokens, and higher temperatures flatten it by giving less probable tokens a greater chance of being selected. Developers should default to a temperature of 0 for tasks requiring correctness, such as classification or structured output, and only increase it when variance is desired, like in open-ended generation.

    LLM temperature is not a creativity dial. Here's what it actually does.

    <p>The single most common mistake I see with LLM APIs is treating <code>temperature</code> like a creativity slider — crank it up for "creative" tasks, turn it down for "serious" ones. That mental model is wrong, and it quietly costs people correctness in production.</p> <p>Tempe…
