Microsoft limits Claude Fable over data concerns

Microsoft is restricting employee access to Anthropic's new Claude Fable 5 AI model due to concerns over its data retention policies. While the model was quickly made available to external customers through services like GitHub Copilot, internal use at Microsoft is limited. This restriction stems from Anthropic's updated data retention requirements, which differ from the Zero Data Retention (ZDR) rules that govern other Claude models still accessible to Microsoft employees. The company is prioritizing data privacy and security, leading to this cautious approach with the latest AI release.
