Temperature

A parameter controlling AI output randomness. Low temperature (0.1-0.3) produces predictable, focused text. High temperature (0.7-1.0) produces creative, varied outputs.

Why it matters

Temperature is the one dial that most changes AI output feel, and many tools expose it. It matters because the right setting depends on your task: you want boring reliability for facts and code, but variety and surprise for brainstorming or creative writing. Knowing it exists explains why the same prompt can give identical answers one day and wildly different ones another.

A concrete example

Ask for a company slogan at low temperature and you'll get safe, predictable lines, often the same one repeatedly. Crank it up and you'll get quirky, unexpected options worth stealing ideas from. Flip it: for "extract the total from this invoice," you want low temperature so it doesn't get creative with your numbers. Match the dial to whether you need consistency or imagination.

How to use it

Use a low setting for anything where there is a right answer or a required format — extraction, classification, code, structured output — and a higher one for brainstorming, naming and creative variation. If you are getting inconsistent results from a task that should be deterministic, temperature is the first thing to check. If everything you generate sounds the same, raising it is a quick way to get genuine variety instead of rephrasings.

The common mistake

Reaching for temperature to fix quality. It controls variability, not correctness. A low temperature makes a wrong answer consistently wrong, and a high one does not make a model smarter — it just makes the mistakes less repetitive.
