Claude Haiku 5.5
What happened
Anthropic released Claude Haiku 5.5, its fastest and most capable small model, aimed at high‑volume, cost‑sensitive tasks such as summarization, database queries, and browser use. The model runs about 75% cheaper than its predecessor Haiku 4.5 and offers an adjustable effort setting for balancing cost and intelligence. Benchmarks show strong performance on OSWorld, GDPval‑AA, and Humanity’s Last Exam, and early customer tests report up to 30% lower latency and up to 2.5× faster inference per agent turn. Pricing improvements also extend to Claude Sonnet 5.5, and new API credits are offered to Claude Max, Ultra, and Team subscribers.
Why it matters
For ordinary readers, the cheaper and faster model could mean lower costs and quicker responses in AI‑powered services they use, such as customer support bots or document search tools. It also signals that AI providers are focusing on efficiency as well as raw capability.
Reality check
An automated, sceptical read of the sourceIncremental. The announcement improves speed, cost, and flexibility of an existing small‑model line but does not introduce fundamentally new capabilities.
