Haiku 5.5 — free AI assistant built on the fastest small Claude model

Haiku 5.5

Haiku 5.5 is a free online workspace for Anthropic's fastest small Claude model. It handles the high-volume work that runs millions of times rather than once — summaries, classification, context compaction, database queries and lookups — at roughly 75% less cost than Haiku 4.5. An adjustable effort setting lets one model cover a quick draft and a careful answer, and on coding tasks it works as a subagent beside Opus 5.5 and Sonnet 5.5. Start in the browser, bring in a document or a batch of records, and let Haiku 5.5 do the repetitive work.
