Copilot Studio goes multi‑agent
Microsoft launched major Copilot Studio updates that make multi‑agent orchestration generally available, adding faster prompt iteration, governance tools, Copilot Cowork for collaborative flows, and a Critique mode to compare outputs across LLMs. The release pushes multi‑agent, multi‑model orchestration and PromptOps into mainstream enterprise tooling.

Microsoft’s Researcher agent now runs a two-step “draft + reviewer” Critique flow that uses one model to generate research output and a second model (for example, OpenAI’s GPT and Anthropic’s Claude) to review and flag sourcing and accuracy issues. (techcommunity.microsoft.com) Copilot Cowork was opened to customers through Microsoft’s Frontier early‑access program on March 30, 2026, making the long‑running orchestration experience available to Frontier members. (microsoft.com) Cowork is designed to execute multi‑step plans across Microsoft 365—turning a prompt into a plan and then acting across Outlook, Teams, Word, Excel, PowerPoint, files and calendars with built‑in checkpoints for human approval. (windowsforum.com) The Researcher upgrade includes both Critique and a Model Council (Council) view that surfaces side‑by‑side responses from different model vendors so teams can compare evidence, citations, and confidence metrics. (techcommunity.microsoft.com) Microsoft has expanded model choice in Researcher to include Anthropic’s Claude alongside OpenAI’s GPT, a capability Microsoft first announced as an opt‑in model choice in September 2025. (support.microsoft.com) Copilot Studio’s agent orchestration updates build on prior Build 2025 investments—Copilot Tuning (a low‑code tuning path) and an Agent Store for publishing and reuse—with Copilot Tuning entering early access beginning in June 2025. (microsoft.com) Microsoft’s Wave 3 roadmap embeds these agentic and multi‑model capabilities directly into Word, Excel, PowerPoint, Outlook and Copilot Chat as part of a broader push to make long‑running, governed AI workflows a platform capability for enterprise customers.
