AWS has announced that Claude Opus 5.5, described by Anthropic as its most capable Opus model, is now available on Amazon Bedrock and the Claude Platform on AWS. The model is positioned for agentic coding, knowledge work, and long-running tasks. The accompanying AWS post outlines what is new in Opus 5.5, offers practical guidance, and explains how to begin building with the model on Amazon Bedrock.
Why it matters
Availability through Amazon Bedrock and the Claude Platform gives AWS customers a direct path to use the model within their existing cloud environment for coding and knowledge-work applications.
Who should care
Developers and organizations building agentic and long-running task workflows on AWS, particularly those already using Amazon Bedrock, are the primary audience for this release.
