Haiku is Anthropic's smallest, fastest, cheapest model — perfect for short tasks and chatbots.
Builders · Model Families · ~24 min read
The big idea
Claude Haiku is the smallest Claude. It answers in milliseconds and costs almost nothing per request, so devs use it for chatbots and quick lookups. It's not great at long, hard reasoning.
Some examples
- Use Haiku for autocomplete or instant suggestions.
- Haiku powers fast helper bots in apps where speed beats depth.
- Skip Haiku for math, code, or anything multi-step.
- On the API, Haiku is cents per million tokens vs dollars for Opus.
Try it!
If you have API access, run the same prompt on Haiku and Sonnet. Compare speed and quality. Notice the trade-off.
Practice this safely
Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.
- 1Ask AI to explain Haiku in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "AI and Claude Haiku: The Tiny Speed Demon" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check small model against a trusted source, teacher, adult, expert, or original document before you use it.
