Microsoft restricts Claude Fable for employees over data retention concerns

Anthropic released Claude Fable, its first Mythos‑class AI model, and Microsoft is already curbing internal access. Sources say the company has blocked employees from using Claude Fable 5 due to Anthropic’s new data‑retention requirements, even though the model remains available to GitHub Copilot and Foundry customers. The restriction shows up as the model’s omission from Microsoft’s internal Copilot model picker.
