Microsoft's AI tool claims superior diagnostic accuracy over doctors

Microsoft's AI-powered diagnostic tool claims to outperform human doctors in identifying medical conditions, according to a study published in Science on October 22, 2026. The AI system, developed by Microsoft AI CEO Mustafa Suleyman, was tested against human physicians on medical scenarios derived from case reports and emergency department data. The findings suggest the AI can diagnose conditions up to four times more accurately than human doctors. Microsoft created its own benchmark dataset, S, to evaluate the AI's performance. Suleyman stated, 'It is finally here' for AI in healthcare, highlighting its potential impact. The study's publication in Science underscores the credibility of the findings and signals a possible shift in medical diagnostics, though further validation and real-world application remain to be seen.
