Microsoft Integrates GPT and Claude for Collaborative Work

Microsoft announced Critique and Council for simultaneous GPT and Claude collaboration.

Microsoft has announced two features for its Copilot Researcher tool — Critique and Council. These features enable GPT models from OpenAI and Claude from Anthropic to work simultaneously on a single task to enhance accuracy.

Critique is a new multimodal deep analysis system designed specifically for tackling complex research processes. The tool employs a combination of neural networks from leading labs.

“One model guides the generation phase, planning the task, iterating through information retrieval, and creating an initial draft. The other is responsible for verification and refinement, acting as an expert reviewer,” Microsoft stated.

Meanwhile, LLM can switch their roles.

The company emphasized that all modern AI research tools operate similarly, with no one verifying their work. Critique aims to address issues of hallucinations, citation errors, and the provision of false or inaccurate statements.

In the DRACO test, which covers 100 complex research tasks across 10 domains, Critique scored 57.4 points, while Claude Opus 4.6 scored 42.7.

The second feature, Council, employs a different approach to problem-solving. It runs GPT and Claude in parallel and presents their full reports side by side. Then, a third model-judge reads both responses and writes a summary, explaining where the AI models agree and where their arguments diverge.

In Critique, LLMs collaborate with each other, whereas in Council, they compete.

Critique is the standard mode in Researcher, while Council must be selected from the menu. Both features are available to users registered in the Microsoft Frontier program.

Back in March, the corporation introduced the AI agent Cowork for performing complex tasks in Microsoft 365. It is capable of interacting with ecosystem applications like Outlook, Teams, Excel, PowerPoint, and SharePoint.
