- Claude Fable 5.1 is now generally available on AWS, delivering frontier‑level intelligence for coding, scientific research, and enterprise workflows with better reasoning and fewer confident errors.
- Designed for long‑running, high‑stakes work, it can own features across a codebase, perform code review, and explicitly report when it gets stuck instead of fabricating success.
- Accessible via Amazon Bedrock and Claude Platform on AWS, with Enterprise Frontier Safeguards that keep data under customer‑controlled cloud environments; Claude Mythos 5.1 (same model) is offered with limited access.
