AWS now offers Claude Opus 5.5, Anthropic’s most capable Opus model yet and, the first of the Claude 5.5 model family, a better collaborator that handles long-running coding and knowledge work, reporting back clearly on what it did, what it found, and what it needs next.
According to Anthropic, Claude Opus 5.5 completes tasks using fewer tokens than Claude Opus 5, at a lower price per token, with cheaper cache reads stacking on top of the efficiency gain. Claude Opus 5.5 is the enterprise workhorse, a clear step up from Opus 5 on the work teams count on Opus to do. It handles long-running coding and knowledge work, and reports back like a good teammate, surfacing what it did, what it found, and what it needs from you. It thinks adaptively on every request, deciding how much effort each task needs.
Customers have two ways to access Claude Opus 5.5: Amazon Bedrock and Claude Platform on AWS: Amazon Bedrock gives you Opus 5.5’s advanced capabilities with zero data retention (ZDR) support by default. It keeps your data within AWS infrastructure with regional data residency and provides access through a unified service with AWS-managed features like Guardrails and Knowledge Bases. To learn more, see the Amazon Bedrock documentation and regional availability.
Claude Platform on AWS gives you direct access to Anthropic’s native platform experience and capabilities via the AWS Console. Build, test, and deploy with the same APIs, features, and console experience you’d get working with Anthropic directly, unified with AWS billing and authentication. To get started, see the Claude Platform on AWS documentation.
