Microsoft Expands Copilot Cowork and Introduces Critical AIs

Microsoft Expands Access to Copilot Cowork

Microsoft recently announced an expansion of access to "Copilot Cowork," a feature that leverages Claude Cowork to provide advanced task management capabilities. This system not only allows for multi-step task management but also enables users to access and produce files, schedule calendars, and provide daily briefings. This feature is now available as part of the Frontier program.

Advanced Features of the Researcher Tool

Microsoft's "Researcher" tool has been enhanced with a new function called "Critique." This innovative feature allows an artificial intelligence model to draft a document, which is then revised by a second model. The models used come from Anthropic and OpenAI. Microsoft claims that this approach achieves top-tier in-depth research performance, surpassing Perplexity by 7 points thanks to Claude Opus 4.6. However, it is worth noting that Microsoft's benchmark does not compare these results with the in-depth research model based on GPT-5 from OpenAI.

Comparison with "Model Council"

Another new feature introduced in the Wave 3 of Microsoft 365 Copilot is the "Model Council." This option allows users to compare the responses of different AI models side by side to determine where they agree or diverge. This feature aims to provide increased transparency and help users choose the model best suited to their specific needs.
