Posted on: Aug 13, 2026

AWS GovCloud (US) now offers Claude Opus 5 — the most advanced Opus model yet, and compatible with zero data retention (ZDR) — bringing a step-change in coding, long-running agents, and complex professional work to teams building at the highest level. Claude Opus 5 is available via the bedrock-runtime endpoint in both AWS GovCloud (US) regions, and available via the bedrock-mantle endpoint in AWS GovCloud (US-West)

Claude Opus 5 delivers advances in coding, understanding and navigating codebases like an experienced engineer and writing production-quality code while adapting its strategy as it works. It powers dependable agents that run for hours and even overnight, finding paths around obstacles, recovering from errors, and reaching their objectives. And it brings deeper reasoning to long documents and higher accuracy to complex analysis, with the largest gains on document-heavy enterprise work. 

Amazon Bedrock offers Claude Opus 5 with zero data retention (ZDR) enabled by default, giving you Opus' top-tier intelligence while meeting your data governance requirements. 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.
