Microsoft's AI diagnostic system outperforms generalist doctors on hard cases, study finds

A study published in Science reports that Microsoft's new AI diagnostic system outperformed generalist doctors when handling difficult medical cases. Much of the gain, however, appears to stem from the underlying AI models the system is built on rather than from Microsoft's own system design. The findings are part of Microsoft AI chief Mustafa Suleyman's broader push toward what he calls 'medical superintelligence.' The results highlight both the promise of AI in diagnosis and questions about where the real advances originate.
