Summary written from the original first-party source — the link to it is at the end of this post.
What happened: Anthropic released Claude Haiku 5.5, which it calls its fastest, cheapest and most capable small model yet. It is built for high-volume, cost sensitive work such as classification, summarization and extraction, including live support, voice agents and in-app assistants. Anthropic says it costs around 75% less to run than Haiku 4.5, and it is available on the Claude Platform, Amazon Web Services, Google Cloud and Microsoft Azure.
Context: Haiku 5.5 is the third model in Anthropic’s Claude 5.5 family in a month, following Opus 5.5 and Sonnet 5.5, extending the lineup across the price range ahead of a planned IPO.
Why it matters: Cheaper small models change what is worth doing at scale. Tasks that were too expensive to run on every request, like classifying, routing or summarizing, become affordable per call, which is exactly where agent pipelines spend most of their tokens.
