Overview
What is Claude Haiku 4.5?
Claude Haiku 4.5 is the fast, economical model in the Claude line-up, offering the lowest latency and lowest cost of any current option. It is purpose-built for high-volume, real-time work: classification, extraction, routing, and customer support where responses must be near-instant and run at massive scale. For corporate teams, Haiku is the model that makes AI affordable in production, letting you process millions of requests without the cost or latency of the larger models. The skill in using Haiku well is recognizing the many tasks that do not need deep reasoning, and confidently routing them here instead of reaching for Sonnet, Opus or Fable 5 out of caution. Learning to design tight prompts and clear output formats lets Haiku handle repetitive work reliably at a fraction of the cost. Teams that use Haiku for the right jobs cut their AI spend dramatically while keeping their frontier capacity free for the problems that genuinely need it.
