How to use

How to use the Temperature Explainer

  1. Drag the Temperature slider between 0 and 2.
  2. Drag the Top-p slider between 0 and 1.
  3. Read the explanation for each setting below the sliders.
  4. Change only one of the two at a time, as the tip suggests.
Worked example

An example, step by step

You enter

Temperature 0.2, top-p 0.9

The tool shows

Temperature 0.2: low, focused and repeatable, good for factual answers and structured output. Top-p 0.90: trims only the long tail of unlikely tokens

FAQ

Questions about the Temperature Explainer

What temperature should I use for code or data extraction?

Use 0 or close to it, so the model picks the most likely token each time and results are repeatable. The explainer calls 0 greedy or deterministic.

What is the difference between temperature and top-p?

Temperature reshapes the whole probability distribution, while top-p keeps only the smallest set of tokens whose probabilities add up to p and samples from those.

Should I change temperature and top-p together?

Usually change only one. Adjusting both makes it hard to tell which caused a change in output.

Is the Temperature Explainer free and private?

Yes. It is free, needs no sign-up and runs entirely in your browser, so what you type is not uploaded. You only sign in if you want to email a result to yourself or save it to your CareerByteCode profile.
