Claude Haiku 5.5

Introducing Claude Haiku 5.5: the cheapest, fastest, and most capable small model we’ve ever released. Claude Haiku 5.5 is designed for high-volume, cost-sensitive tasks. It reliably handles quick and repetitive workloads (like summaries, compactions, database queries, and classification requests). It pairs well with Opus 5.5 and Sonnet 5.5 as a subagent on coding work. And, since it’s also our fastest model to date, it works especially well for speed-sensitive tasks like live customer support and browser use.¹ Haiku 5.5 is available at a much lower price than Haiku 4.5.
