Temperature
Definition
A setting that controls how creative or predictable an AI's output will be. Low temperature (closer to 0) makes the AI stick to safe, expected answers. High temperature (closer to 1 or 2) makes it more creative and unpredictable. For factual tasks, low temperature is better. For brainstorming or creative writing, higher temperature can be useful.
Why It Matters
You will mostly meet this setting in developer tools, the ones programmers use to build with these models, not in the everyday chat apps. Some of the newest models now ignore it altogether. Knowing what it means helps when you read about it, and it explains why asking in plain words for 'more surprising' or 'more careful' works.
What does that look like in practice?
Set temperature low and the AI plays it safe; turn it up and you'll get wilder, more surprising brainstorms.
What people actually mean when they say this
When someone says 'make it more creative,' they are describing what temperature does. The everyday ChatGPT, Claude and Gemini apps don't usually show a temperature dial, so you do the same job with words: ask for wilder ideas, or ask it to stick to the facts.
