AWS says both Anthropic models are now on Amazon Bedrock through US Geo and Global cross-region inference profiles, and on Claude Platform on AWS. Fable 5.2 is treated as a covered model, so Bedrock users must set the aws_review data retention mode before calling it. By default that means retention for up to 30 days and human safety review. Mythos 5.2 is limited to approved cyber security and life sciences work. On Bedrock, retrying a declined request is the job of your own code, as there is no automatic switch.
