🔒Anthropic Launches Zero Data Retention for Enterprise Fable Users
Enterprises can now opt for zero data retention with Fable
TL;DR
Anthropic introduces zero data retention for enterprise Fable users, subject to approval. The new Enterprise Frontier Safeguards (EFS) service combines privacy and model abuse detection, shifting safety work to enterprise customers.
Anthropic is rolling out zero data retention (ZDR) for enterprise customers using the Fable model, but it's not automatic. Enterprises must apply for ZDR agreements, which are part of the new Enterprise Frontier Safeguards (EFS) service. This service combines privacy and model abuse detection, storing data in customer-controlled cloud infrastructure. The move addresses enterprise concerns over non-zero data retention policies, where inputs and outputs are typically retained for 30 days. EFS will be available for select models and platforms this fall, including Claude Code, Claude Enterprise, and Amazon Bedrock.
