Introducing Claude Haiku 5.5

Anthropic announced the launch of Claude Haiku 5.5, its cheapest, fastest, and most capable small model to date. The model is designed for high‑volume, cost‑sensitive workloads such as summarization, database queries, classification requests, and live customer support. On average, Haiku 5.5 costs about 75% less to run than the previous Haiku 4.5, and it is Anthropic’s fastest model, making it well suited for speed‑sensitive tasks like browser use. The release also introduces an adjustable effort setting, allowing users to balance cost against intelligence. Anthropic has further reduced the price of cache reads for Claude Sonnet 5.5, cutting that cost by 50% and lowering overall agentic task costs by roughly 20%. Additionally, the company is rolling out monthly API credits for Max and Team subscribers—$100 for Max 5x, $200 for Max 20x, and up to $500 pooled for Team users—to encourage experimentation with new agents and applications on the Claude Platform. The company has updated its Python and TypeScript SDKs to support computer and browser use in beta, emphasizing Haiku 5.5’s suitability for these tasks. These changes reflect Anthropic’s strategy to enhance the value proposition of its model range while supporting developers and enterprises in building cost‑effective AI solutions.
