Definition
Temperature is a setting that controls how predictable or random an AI’s responses are, dialing it between consistent, safe answers and varied, creative ones.[1]
At a glance
- Low temperature (near 0) gives focused, repeatable, fact-leaning answers; high temperature gives diverse, surprising, more creative ones.[1]
- Typical range is 0 to 2, with 1.0 as the common default; many tools start around 0.7 as a balanced middle.[2]
- Use low for support replies, summaries, data, and code; use high for brainstorming, marketing copy, and storytelling.
- Even at temperature 0 outputs are not perfectly identical every time, so do not treat it as a guarantee of sameness.[4]
What it actually controls
The AI picks each word from a ranked list of likely options, and temperature reshapes that ranking[3]. Low temperature makes the top choice dominate, so the AI plays it safe. High temperature flattens the odds, letting less-likely words slip in, which feels more creative but raises the chance of off-topic or odd output.
How to set it for your business
Match the dial to the job. For accuracy-critical work like customer answers, contracts, finance, or healthcare, keep it low for consistency and fewer surprises[2]. For ideation, ad headlines, or first drafts, raise it to get more variety. When unsure, start near 0.7 and adjust based on results.
Bottom line
Temperature is the AI’s creativity dial: turn it down for reliable, repeatable answers and up for fresh, varied ideas, matched to the task at hand.
