Gate News update. On March 31, Monday, Microsoft announced two new features for Copilot Researcher—Critique and Council—combining OpenAI’s GPT and Anthropic’s Claude for the same research tasks. Critique uses a sequential collaborative mode: GPT is responsible for planning the research, retrieving sources, and drafting an initial report, and then Claude acts as a reviewer to verify factual accuracy and the quality of citations; Council, meanwhile, lets the two models generate reports in parallel independently, and then a third judge model compares differences and summarizes disagreements. In the DRACO benchmark test covering 100 complex research tasks across 10 fields including healthcare, law, and technology, Copilot with Critique scored 57.4, nearly 14% ahead of second place, far exceeding the 42.7 score Claude Opus achieved when running alone.
