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

Microsoft's AI Diagnostic Orchestrator, powered by OpenAI's GPT-5, demonstrated up to four times higher accuracy than human doctors in diagnosing medical conditions using case reports and emergency data. The system uses multiple AI agents to mimic doctors' diagnostic processes and outperformed both physicians and standalone AI models in peer-reviewed tests. Microsoft plans to open-source its benchmark dataset, SDBench, but notes that widespread deployment will require further development.
