Researcher's advantage is not the model. It is that the agent can read the meeting notes, decks and email threads where most company answers actually live.

What does Copilot Researcher do?
Researcher is an agent in Microsoft 365 Copilot built for complex, multistep research. It can ask clarifying questions, then searches the web, your work content or both, and returns a structured report with cited sources, sections and charts that can become a document or presentation. It replaces the earlier Copilot Deep Research (Microsoft Support).
On March 30, 2026 Microsoft announced Critique, in which GPT drafts and Claude reviews for accuracy, completeness and citation integrity, and a Council view that compares answers from different models side by side (The Letter Two). Microsoft reports a 13.8% improvement on the DRACO deep research benchmark; that is its own figure (Petri).
