Haiku
The fastest, most compact model in the Claude family, designed for near-instant execution of high-volume, low-latency tasks.
What it is
Haiku is Anthropic's entry-level model tier. It sacrifices deep, complex reasoning in exchange for extreme speed and cost efficiency. It excels at rapid data extraction, basic log analysis, and acting as a fast triage agent before passing complex tasks to heavier models.
When you would use it
You use Haiku when speed and cost are your absolute highest priorities, and the task requires basic pattern matching rather than complex coding or reasoning.
Common operations
- Analyzing thousands of simple text documents rapidly.
- Serving as a fast routing agent to determine user intent in a chat application.
