New M365 Copilot Critique and Council features

M365 Copilot Researcher agent is adding new capabilities for deep, complex research. There are two new features: Critique and Council.

Critique is a multi-model research workflow that lets you use different models including to research.  This allows you to use both Anthropic and OpenAI to generate and improve an answer.  For instance, one model plans the work, retrieves information, and drafts the response; a second model reviews and refines the draft to produce the final output. Then the second model focuses on review and refinement, acting as an expert reviewer of the final research response. 

Council is designed for side-by-side model comparisons. Council is different approach and is designed for side-by-side comparison across multiple models.  In this case, Councill will run both Anthropic and OpenAI in parallel and will present a report shown at the end as a comparison between both models.  Once this is completed, a dedicated judge model evaluates both reports and then uses a judge model to synthesize the key findings.
