Microsoft Limits Internal Use of Anthropic's Claude Fable 5 Amid Data Policy Review

Microsoft has placed a restriction on the internal use of Claude Fable 5, the latest AI model from Anthropic, while its legal and compliance teams review the platform’s data‑retention and privacy practices. The limitation applies only to Microsoft’s own operations; customers can still access the model through selected Microsoft‑supported services. The move reflects growing corporate scrutiny of how AI systems store user prompts and responses, and underscores the importance of data protection, compliance and risk management in enterprise AI adoption.

Separately, Microsoft CEO Satya Nadella warned that if the benefits of artificial intelligence remain concentrated in a small number of firms, entire industries could lose value, expertise and competitiveness. He urged companies to develop their own AI capabilities and to pair them with strong human capital, arguing that a broader distribution of AI “token capital” is essential to avoid economic imbalance and over‑reliance on a few dominant models.
