Microsoft’s Copilot is getting even better at research thanks to a new feature that combines the power of both OpenAI’s ChatGPT and Anthropic’s Claude. In a blog post announcing Copilot Cowork’s availability, Microsoft debuted the Critique feature that will be used in Microsoft 356 Copilot’s Researcher tool. Unlike the standard Copilot, Researcher is designed to tackle more complex tasks with multiple steps.

Now, Researcher is getting even better at that with the Critique feature that uses GPT responses, which are then refined by Claude. In a blog post, Microsoft said that, “this architecture creates a powerful feedback loop that delivers higher-quality results across factual accuracy, analytical breadth, and presentation,” adding that Researcher’s process is similar to what you see in “academic and professional research settings.” Microsoft claims the upgrade scores somewhat higher (compared to the most recent Perplexity Deep Research models) on the Deep Research Accuracy, Completeness, and Objectivity benchmark. On its own, Anthropic has a Research feature that can use multiple Claude agents to provide a comprehensive response to more complex requests.

If you prefer doing research with a little more autonomy, Microsoft also added the Model Council feature that’s available as an alternative option for Researcher. With Model Council, you’ll get side-by-side responses from both Anthropic and OpenAI, with a report that shows where the models agree and disagree. Both features are currently available in Microsoft 365 Copilot’s Frontier program, which acts as a early access space for the company’s AI innovations.
