Nvidia, Palantir, and Booz Allen Limit Usage of Fable Due to Data Storage

It’s risky to use an API built on top of another API because you’re putting all of your sensitive information into someone else’s hands. For me personally, I don’t mind using Fable for my day-to-day life, but if I was working on proprietary code or client data, I’d need to make sure that I understood what the retention policy was. Thankfully, Anthropic has a client-side log retention mode, and that’s exactly how they should be handling this.

Palantir blocks Fable and demands “ironclad zero retention guarantees” following Anthropic’s change in their logging policies.

Palantir blocks Fable and demands “ironclad zero retention guarantees” following Anthropic’s change in their logging policies.
