Anthropic Launches Claude Haiku 5.5, Its Fastest and Lowest-Cost Small Model Yet

Anthropic has released Claude Haiku 5.5, a compact model built for large-scale, budget-conscious work. The company calls it the most affordable, quickest and most capable small model it has shipped. Haiku 5.5 targets routine, high-volume jobs such as summarising, compacting context, querying databases and classifying content. Anthropic also positions it as a helper agent alongside Opus 5.5 and Sonnet 5.5 on coding projects. Its speed makes it a good match for time-critical uses like live customer support and browser automation. On average, Haiku 5.5 costs about 75% less to run than Haiku 4.5.
