multi-model

Microsoft is expanding Copilot Cowork availability and introducing a Critique function that enables one AI model to review another's output. The update also includes a new Researcher agent claiming best-in-class deep research performance, outperforming Perplexity by 7 points, and a Model Council feature for direct model comparison.

Microsoft has enabled its Copilot Researcher tool to simultaneously leverage OpenAI's GPT and Anthropic's Claude through two new features: Critique, which uses GPT responses refined by Claude, and Model Council, which displays side-by-side outputs with agreement/disagreement analysis. Both features are rolling out in the Microsoft 365 Copilot Frontier early access program.
