Claude Haiku 5.5 is a language model made by Anthropic. The company describes it as their fastest and most capable small model. It is designed for high-volume work, which means tasks that need to run quickly and in large numbers. Typical uses include summarizing long documents, running sub-agents inside a larger AI system, and controlling web browsers.
A "subagent" is a smaller AI task that runs inside a bigger one, handling a piece of the overall work.
Anthropic released Claude Haiku 5.5 in early October 2026. The model doubles the performance of its predecessor while cutting costs by up to 90%, making it one of the cheapest options on the market. That sharp price drop has intensified competition among AI providers, pushing rivals to lower their own prices.
The model is available on Claude.ai for free, Pro, Max, Team, and Enterprise users, and can be accessed on the web, iOS, and Android. Developers who want to build their own applications can also use it through the Claude Platform, as well as on Amazon Web Services, Google Cloud, and Microsoft Foundry.
With its combination of low cost and strong performance, Claude Haiku 5.5 is aimed at use cases where speed and volume matter more than top-tier reasoning ability, such as routine automation and large-scale text processing.
It is built for high-volume tasks like summarizing documents, running sub-agents inside larger AI systems, and controlling web browsers. It is meant to be fast and affordable rather than the most powerful model Anthropic offers.
Anthropic cut prices by up to 90% compared to the previous version. It is available for free, Pro, Max, Team, and Enterprise users on Claude.ai, and developers can also access it through cloud platforms including AWS, Google Cloud, and Microsoft Foundry.
It was developed by Anthropic, an AI company based in the United States. The model was released in October 2026.
