Claude Fable 5.2 and Claude Mythos 5.2 now available on Amazon Bedrock
AWS announces that Anthropic's Claude Fable 5.2 and Claude Mythos 5.2 are now available on Amazon Bedrock and Claude Platform on AWS. Fable 5.2 targets complex coding, math, and science work and can run unattended for hours to days; Mythos 5.2 covers cybersecurity and life sciences via Anthropic's verification programs. Fable 5.2 is designated a Covered Model, requiring by default up to 30 days data retention and human safety review via the aws_review mode, or zero data retention through Enterprise Frontier Safeguards until June 30, 2027. The post also covers migrating with the claude-api skill in Claude Code and invoking the model via Boto3, AWS CLI, and SDKs.
This official AWS launch post details model positioning, data retention and EFS options, and Bedrock invocation and migration paths, helping readers assess integration cost for technical workloads.
