Anthropic announced the launch of the Claude Haiku 5.5 artificial intelligence model on Wednesday, targeted at high-volume enterprise workflows and subagent task execution.[^1]

Anthropic states Claude Haiku 5.5 is the fastest and most efficient model in the Claude 5.5 family. It costs approximately 75% less than Claude Haiku 4.5 for most tasks.[^4]

Alongside the model launch, the company implemented a 50% price cut on cache reads for Sonnet 5.5. This change reduces complex agentic task compute costs by approximately 20%.[^2]

Anthropic also launched an updated Cyber Verification Program on Wednesday, granting tiered reduced-safeguard access to Claude models for vetted cybersecurity teams.[^3]

The company is expanding its artificial intelligence model lineup ahead of a planned initial public offering.[^5]
