Claude Haiku 4 is a light, very fast model from Anthropic. It keeps Claude's signature language quality but answers instantly and costs less. A good fit for quick messaging, short tasks and high query volumes.
Haiku is the youngest in the Claude family, and it has one job: answer instantly. The same recognizable, careful language, just without the pause to think — and noticeably cheaper to run.
It's the pick when there are many requests and each is simple: quick support replies, short messaging, drafts. Where speed and volume matter more than depth, Haiku outpaces the heavy models.
