AWS announced Claude Fable 5.1 on Amazon Bedrock and Claude Platform on AWS the same day as Anthropic’s public launch. Because of its capability level, Anthropic classifies Fable 5.1 as a Covered Model: extra data-retention, safety-review, and access policies follow it onto every host. On Bedrock that means up to 30-day retention and possible Amazon human review unless customers configure data-retention modes and meet enablement requirements.
AWS also highlights Enterprise Frontier Safeguards for eligible customers who want Fable-class power with customer-controlled storage and stronger privacy postures through at least the end of 2026 for internal use paths described in the post. For platform teams, the procurement checklist just got a new row: model quality, price, and “covered” compliance baggage travel together.
