Microsoft says its AI tool is better than doctors at diagnosing conditions
Microsoft claims its AI-powered Diagnostic Orchestrator, built on multiple AI agents and powered by OpenAI's GPT-5, achieved about 83% diagnostic accuracy on cases from New England Journal of Medicine reports versus roughly 36% for generalist physicians with references, and 80% versus 47% on emergency department cases from Beth Israel Deaconess Medical Center, according to findings published in Science. The system, tested only on past medical cases, has not been validated in real clinical settings, and Microsoft says hospital testing with Beth Israel is expected to begin in the next couple of months.
