Microsoft has introduced a series of major upgrades to its Microsoft 365 Copilot platform on March 30, as part of its “Wave 3” rollout aimed at enhancing its AI capabilities. The update brings new features focused on research, automation, and model comparison, further strengthening its position in the AI productivity space.
One of the key highlights is Copilot Cowork, an advanced agentic AI feature that has now begun rolling out to early-access users through the Frontier program. Built on technology similar to Claude Cowork from Anthropic, this tool can autonomously plan and execute tasks across Microsoft 365 apps such as Excel, Outlook, Teams, and PowerPoint. Users can simply describe a task, and Copilot Cowork will carry it out while also providing real-time progress updates, making workflows more efficient and streamlined.
Microsoft has also enhanced its Researcher tool with new capabilities powered by multi-model intelligence. A standout addition is the Critique feature, which improves the quality of outputs by separating the process into two stages. In this system, one AI model generates the initial draft, while another evaluates and refines it. This approach leverages models from leading AI labs, including OpenAI and Anthropic, ensuring better accuracy and objectivity. According to Microsoft, this upgrade has resulted in a 13.8% improvement in performance on the DRACO benchmark, which measures accuracy, completeness, and objectivity in research tasks. The Critique feature is now rolling out as a default option when Auto mode is selected.
Another notable addition is Model Council within the Research tool, which allows users to compare multiple AI models side by side. With this feature, models from Anthropic and OpenAI can generate separate reports on the same topic simultaneously. A third “judge” model then analyzes these outputs, highlighting agreements, differences, and unique insights, helping users make more informed decisions.
Overall, these updates reflect Microsoft’s continued push to evolve its AI ecosystem by combining automation, multi-model intelligence, and deeper analytical capabilities, making Microsoft 365 Copilot a more powerful tool for both individuals and enterprises.
