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

Microsoft unveiled a GPT-5-powered “Diagnostic Orchestrator” that scored 83 percent diagnostic accuracy on New England Journal of Medicine case reports. Generalist physicians scored roughly 36 percent using references and 22 percent without, and 47 percent on emergency department cases.

Microsoft is positioning AI to own high-stakes diagnostic workflows, forcing hospitals and vendors to rethink clinical decision-support architectures and partnerships.
