Microsoft has announced the availability of Copilot Cowork for customers in the Frontier early‑access programme and new features in Researcher, Microsoft 365 Copilot’s deep research agent for work, built on multi-model intelligence.
Copilot Cowork is now accessible to Frontier customers. Built on the same technology platform that powers Claude Cowork, Copilot Cowork makes it easy to delegate long-running, multi-step work in Microsoft 365. Describe the outcome you want and Cowork creates a plan, reasons across tools and files, and carries work forward with visible progress and opportunities to steer.
Microsoft also introduced new features in Researcher built on multi‑model intelligence:
- Critique is a new multi model deep research system designed for complex research tasks. It separates generation from evaluation and utilises a combination of models from Frontier labs, including Anthropic and OpenAI. One model leads the generation phase, planning the task, iterating through retrieval, and producing an initial draft, while a second model focuses on review and refinement, acting as an expert reviewer before the final report is produced.
- With Researcher’s new model Council, you can compare responses from different models side by side, instantly seeing where they agree, where they diverge, and what each uniquely brings to the table. It’s like having multiple researchers at your fingertips.
The results are measurable – Researcher now scores 13.8% higher on the Deep Research Accuracy, Completeness, and Objectivity, or DRACO benchmark, the industry standard for deep research quality.
All of this innovation is part of Wave 3 of Microsoft 365 Copilot, which marks a turning point in how AI shows up at work: intelligence that understands the context of work, and trust that allows AI to scale safely across the workforce.
