A new feature from Microsoft uses Anthropic’s Claude to assess and correct the work of OpenAI’s GPT, blending the tech giant’s new and old AI partnerships in the latest attempt to boost adoption of its Microsoft 365 Copilot tools for businesses.
The company announced the new capability Monday morning as part of updates to Microsoft 365 Copilot’s Researcher agent. A new feature called Critique puts the two models to work in sequence: GPT drafts a response to a research query, and Claude reviews it for accuracy, completeness and citation quality before the response is given to the user.
It’s part of a larger trend of using multiple AI models to improve results. Microsoft says it expects the process to eventually run in both directions, with Claude drafting and GPT critiquing.
The multi-model approach has led to a 13.8% improvement on the DRACO benchmark, an industry measure of deep research quality, putting it ahead of standalone deep-research tools from OpenAI, Google, Perplexity and Anthropic, according to the Redmond company.
The announcement comes as Microsoft tries to accelerate Copilot adoption among its existing base of business customers. The company in January reported 15 million paid Copilot seats, still in the low-single digits, roughly 3.3%, of its 450 million commercial Microsoft 365 users.
It comes amid intensifying competition in enterprise AI. Google has been expanding Gemini across its Workspace apps, Anthropic’s Claude has seen growing adoption among businesses, and OpenAI has been pushing ChatGPT Enterprise and its own deep-research tools.
Microsoft also said Copilot Cowork, its new tool for delegating long-running, multi-step tasks inside Microsoft 365, is now available through its Frontier early access program. The product, first announced earlier this month, is built on technology from Anthropic’s Claude Cowork.
