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.
Haiku 5.5 is available at a much lower price than Haiku 4.5. On average, it now costs around 75% less to run. Along with this launch, we’re making improvements to the value of our model range. We’re halving the price of Claude Sonnet 5.5’s cache reads, which means Sonnet 5.5 now runs around 20% cheaper on most agentic work.
Haiku 5.5 is our first Haiku-class model to come with an adjustable effort setting. This means that, as with our other models, users can decide whether to optimize for cost or intelligence. In early testing, our customers reported results consistent with the performance and cost improvements. Aaron Vinh, Staff Software Engineer at Asana, said: “We’re very impressed with Claude Haiku 5.5, particularly its speed. We saw over a 30% reduction in latency for task completions and up to 2.5x faster inference per agent turn.”
