Microsoft says its AI tool is better than doctors at diagnosing conditions

Microsoft has announced an AI-powered diagnostic tool called the Diagnostic Orchestrator, which it claims can diagnose medical conditions up to four times more accurately than human doctors. The research, published in Science, tested the system against physicians using cases from medical journals and emergency department data. Microsoft's tool, powered by OpenAI's GPT-5, achieved around 83 percent accuracy on New England Journal of Medicine cases versus 36 percent for generalist doctors, and 80 percent on emergency cases versus 47 percent for humans. The system uses multiple AI agents to mimic a panel of medical experts, reasoning through symptoms, ordering tests, and reaching diagnoses, often at lower estimated costs. Microsoft acknowledges the need for clinical validation before widespread deployment and plans to test the system in hospitals with Beth Israel Deaconess Medical Center in the coming months. The company envisions "medical superintelligence" and outlines other areas where AI could assist, such as coordinating care and treatment decisions, while emphasizing that human clinicians will remain central to patient care.
