Microsoft restricts Claude Fable for employees over data retention concerns
Anthropic released Claude Fable 5, a new Mythos-class AI model, which Microsoft has restricted for internal employee use due to data retention concerns. Microsoft allows Claude Fable 5 for external customers but limits its availability internally because it does not comply with their Zero Data Retention policy. Other Claude models remain available to Microsoft employees under stricter data rules.
