🌡️ Temperature Explained Like You're 5

How creative vs predictable AI answers

Day 56 of 149

👉 Full deep-dive with code examples


The Chef Analogy

Ordering at a restaurant:

  • Temperature 0: "Exactly as the recipe says. No surprises."
  • Temperature 1: "Chef's creative interpretation—might be amazing, might be weird!"

Temperature controls how "creative" or "random" AI responses are!


What Temperature Does

When AI generates text, it picks the next word from a list of possibilities.

Low temperature:

  • Often picks "mat"
  • Predictable, consistent
  • Good for: facts, code, specific answers

High temperature:

  • Might pick "floor" or even "moon"
  • Creative, varied, surprising
  • Good for: stories, brainstorming, poetry

How To Choose

  • Need precise, repeatable answers? Use a lower temperature.
  • Need variety and ideas? Use a higher temperature.

What Happens At Extremes

Temperature = 0:

  • Usually the most consistent output (especially with greedy decoding)
  • Very conservative, and often boring

Temperature = 1+:

  • Wild and unpredictable
  • Creative but might not make sense

A Simple Example

Prompt: "Tell me a joke about cats"

  • Lower temperature: more consistent, similar jokes
  • Medium temperature: some variety
  • Higher temperature: more unusual jokes

In One Sentence

Temperature controls how creative versus predictable AI responses are—low for precise tasks, high for creative exploration.
