Microsoft announced the addition of Anthropic's Claude model to Microsoft 365 Copilot. Initially available in the Researcher intelligent research agent and Copilot Studio, it will be expanded to more experiences over time. Users can choose between OpenAI and Claude within the same workflow to adapt to different tasks and enterprise compliance requirements. Multiple media outlets and Microsoft blog posts have mentioned that this integration involves Claude Sonnet 4 and Claude Opus 4.1, emphasizing a multi-model approach "tuned for the job."
For enterprise use, Microsoft support documents indicate that enabling Claude in Researcher requires a Microsoft 365 Copilot license and administrators to enable access to third-party models in the Admin Center. Anthropic models are hosted outside the Microsoft ecosystem and are subject to Anthropic's data processing terms. Microsoft and Anthropic simultaneously confirmed the integration, with industry analysts stating that this will enhance Copilot's flexibility in deep reasoning and agent building scenarios, though broader applications (such as across Office components) are still being rolled out gradually.
