From The Verge: Microsoft is bringing Anthropic’s Claude Sonnet 4 and Claude Opus 4.1 AI models to its Microsoft 365 Copilot today. It’s a big move that expands model choice beyond just OpenAI’s range of models in Microsoft 365 Copilot, and it will allow Microsoft’s customers to access Anthropic models in Researcher and Microsoft Copilot Studio.
“Copilot will continue to be powered by OpenAI’s latest models, and now our customers will have the flexibility to use Anthropic models too — starting in Researcher or when building agents in Microsoft Copilot Studio,” explains Charles Lamanna, president of Microsoft’s business and industry Copilot team. “The addition of Claude Sonnet 4 and Claude Opus 4.1 advances our commitment to bring the best AI innovation from across the industry to Microsoft 365 Copilot, tuned for work and tailored to your business needs.”
Microsoft’s Researcher agent can now use OpenAI’s deep reasoning models or Anthropic’s Claude Opus 4.1. Researcher users will see a “Try Claude” button at the top of the Microsoft 365 Copilot app that provides access to Opus 4.1 instead of OpenAI’s models. “Once you opt-in, you’ll be able to switch between OpenAI and Anthropic models in Researcher with ease,” Lamanna says.
