Anthropic Unveils Claude Haiku 5.5, Cutting Costs by 75%

Anthropic has launched Claude Haiku 5.5, the fastest and most affordable entry-level model in the company’s lineup. Its average cost is approximately 75% lower compared to Haiku 4.5. Claude Haiku 5.5 is primarily designed for mass-market, latency-sensitive tasks such as classification, summarization, query processing, database management, and sub-agent deployment. Anthropic also positions the model for live user support, browser automation, and other scenarios where speed is crucial. This model is the first in the Haiku line to feature adjustable “effort” levels, allowing developers to choose between speed and reasoning quality depending on the task.
