Fable 5 on Amazon Bedrock and Other Clouds

Where Fable 5 lives

Anthropic shipped Fable 5 as a generally-available model across the major AI clouds, not just its own API. At launch on June 9, 2026, you could reach it through:

• the Claude API (direct)
• the Claude Platform on AWS
• Amazon Bedrock
• Google Cloud
• Microsoft Foundry

That breadth made Fable 5 easy to slot into existing cloud workflows, whether your stack was anchored on AWS, Google, or Microsoft.

What you'd get on Bedrock

On any of these platforms, Fable 5 is the safeguarded public edition of the Mythos-class model. It carries Anthropic's safety classifiers (cyber, bio/chem, distillation) that reroute a small share — under 5% — of flagged sessions to Claude Opus 4.8, with the user informed. The underlying capability matches Mythos 5; the difference is the safeguards. Specs include a 1M-token context and up to 128k output.

Why you can't deploy it right now

Despite the wide availability, the June 12, 2026 US export-control directive suspended Fable 5 (and Mythos 5) access. The suspension is currently active across every channel, including Bedrock. Before architecting around Fable 5 on any cloud, confirm the current status on the official notice and status page.
