Claude Fable 5.1, Anthropic's new frontier model is now available on AWS GovCloud (US)

<p>Claude Fable 5.1 is generally available on Amazon Bedrock in AWS GovCloud (US) and brings Anthropic's most capable frontier model to regulated industry customers. Fable 5.1 delivers frontier intelligence for ambitious tasks across coding, scientific research, and enterprise workflows. &nbsp;</p> <p>Claude Fable 5.1 is built for&nbsp;long-running, high-stakes work that runs for hours and spans many applications. It can own more of a software project on its own, handling features across an entire codebase, code review, and performance work over sessions that run for hours. If it gets stuck, it says so instead of reporting success, and it is less likely to take shortcuts like disabling a failing test. It takes analysis from the first question to the finished document, and it is Anthropic's strongest model yet for knowledge work.</p> <p>Anthropic has designated Fable 5.1 a<a href="https://support.claude.com/en/articles/15425695-covered-models">&nbsp;</a><a href="https://support.claude.com/en/articles/15425695-covered-models">Covered Model</a>, a category of Claude models that carry additional data retention, safety review, and access policies wherever they're offered.&nbsp;<a href="https://www.anthropic.com/news/enterprise-frontier-safeguards">Enterprise Frontier Safeguards</a> (EFS) built in partnership between AWS and Anthropic, will let eligible customers use Covered Models while keeping their data in a cloud environment they control.
