Microsoft Copilot Researcher adds multi-AI critique and council

Microsoft Copilot Researcher in Microsoft 365 now includes Critique, where one AI drafts a report and another from Anthropic or OpenAI refines it, and Council, which generates side-by-side reports from multiple models with a judge's summary. These features achieve 13.8% higher scores on the DRACO benchmark than single-model outputs, improving accuracy, depth, and presentation in eight of ten domains. Access is available via the Frontier program.
