  "account": "Anthropic has announced a new service called Enterprise Frontier Safeguards (EFS) that allows enterprise customers to have zero data retention for their Fable model. However, customers must apply for EFS. The company will store data for 30 days unless other arrangements are made. Earlier this year, Anthropic temporarily stored inputs and outputs to review for safety violations. This short retention period is not for training purposes. Enterprises prefer data retention for safety and security, even though Anthropic assures them it does not train on their data. OpenAI has a similar service, Private Safety Processing, to check for risky interactions without violating zero data retention agreements. To address enterprise concerns, Anthropic will release EFS this fall, storing data in customer-controlled cloud infrastructure. This shifts safety monitoring to customers, who can review detected patterns.",
