Anthropic is introducing a 30-day data retention policy for its Fable and Mythos models to support safety work and detect potential misuse. This policy applies to organizations using these models through various platforms, including AWS Bedrock, Google Cloud Agent Platform, and Microsoft Foundry. The retained data will be used to analyze patterns of misuse and will be deleted automatically after 30 days, unless flagged by automated trust and safety systems or required by law. Organizations can configure data retention settings through their respective platforms.
