Claude is now available in Microsoft 365 Copilot

Today, Microsoft announced that Claude models are now available in Microsoft 365 Copilot, bringing Claude to millions of enterprise users through Microsoft's productivity platform.

Starting with Microsoft's Researcher agent and Copilot Studio, enterprise customers can now choose Claude Sonnet 4 and Opus 4.1 alongside existing model options, giving organizations greater flexibility to select the right AI for their specific business needs.

The addition of Claude Sonnet 4 and Claude Opus 4.1 help Microsoft bring the best AI innovation from across the industry to Microsoft 365 Copilot, tuned for work and tailored to your business needs.

How Anthropic models now show up in Microsoft 365 Copilot:

• Researcher agent: Microsoft’s reasoning agent can now be powered by Claude Opus 4.1. Whether you’re building a detailed go-to-market strategy, analyzing emerging product trends, or creating a comprehensive quarterly report, you can now select your preferred model to power in-depth work. Researcher helps you tackle complex, multistep research—reasoning over not only the web and trusted third-party data, but all of your work content across your emails, chats, meetings, files, and more to deliver highly-skilled expertise on demand—and now you have model choice.
• Copilot Studio: Claude Sonnet 4 and Claude Opus 4.1 models are now available as model options in Copilot Studio, enabling you to easily create and customize enterprise-grade agents. With this launch, you can build, orchestrate, and manage agents powered by Anthropic models for deep reasoning, workflow automation, and flexible agentic tasks. With multiagent systems and prompt tools in Copilot Studio, you can choose Claude for specialized tasks as you see fit.

Once you opt-in, you’ll be able to choose Claude in Researcher with ease.
