Microsoft has introduced new features to its 365 Copilot platform, including a new Critique mode for its Researcher agent and a soft launch of its Copilot Cowork feature. The company claims that this mode allows the agent to use two separate models, one for generating the research report, and another for reviewing the results. The new mode is designed to create higher-quality results across factual accuracy, analytical breadth, and presentation. Additionally, Microsoft has introduced a new Council mode for the Researcher, which simultaneously uses an Anthropic model and an OpenAI model to complete the same task. The feature is available for early adopters through the company's Frontier program.
