Anthropic announced that Claude Haiku 5.5 is now accessible through Amazon Bedrock and the Claude Platform on AWS. Described as the fastest and most efficient model in the Haiku 5.5 family, it targets subagents and high‑volume, cost‑sensitive workloads and costs roughly 75 % less than Claude Haiku 4.5 for most tasks. The model introduces effort controls that let users balance cost against intelligence per request, and it supports coding, tool use, computer use, image handling, and standard NLP tasks.
The service integrates with existing AWS controls such as IAM, CloudTrail, CloudWatch, and Bedrock Guardrails, and usage appears on the regular AWS bill. Claude Haiku 5.5 is available in US, EU, AU, JP, Global, and GovCloud regions, and can be accessed via the Bedrock console, the Anthropic Messages API, or the AWS CLI/SDKs, making it a practical option for developers and learners building scalable AI applications.
