AWS announced that Claude Fable 5.2 and Claude Mythos 5.2 are available on Amazon Bedrock and Claude Platform on AWS. AWS describes Fable as a model for coding, science and long-running tasks; Mythos access requires Anthropic verification for cybersecurity and life sciences work.

Fable use defaults to retention for up to 30 days and human safety review, performed by Amazon personnel within AWS. Enterprise Frontier Safeguards is available with zero data retention, and eligible customers can use Fable with zero data retention through June 30, 2027. A version that stores data in customer-controlled buckets under customer-controlled keys has not launched.
