The Information reports that Nvidia, Palantir and Booz Allen Hamilton have all restricted internal use of Anthropic's Fable model, following a June policy change that gave Anthropic the right to retain usage logs for 30 days to defend against what it described as complex and novel attacks. According to the report, a major US utility pulled a Fable deployment used for core power infrastructure after Anthropic declined to sign a non-revocable zero-data-retention clause, and Booz Allen has barred the model from proprietary cybersecurity work for clients. It is a reminder that in regulated and defense-adjacent industries, data handling terms can outweigh model quality. Whether Anthropic revisits the policy is the thing to watch.
