Anthropic released Claude Haiku 5.5, a small model priced at roughly a quarter of Haiku 4.5's running cost, and halved the price for cache reads on Claude Sonnet 5.5.
Claude Haiku 5.5 is now available on Amazon Bedrock and Claude Platform on AWS. Anthropic describes it as the fastest and most efficient model in the Claude 5.5 family, aimed at subagents and high-volume, cost-sensitive work, costing around 75% less.
Why it matters: It gives AWS customers a cheaper, faster Claude model option for high-volume and subagent workloads.
