Microsoft’s Mustafa Suleyman says its AI outperforms doctors on hard cases as he chases ‘medical superintelligence’
Microsoft's AI diagnostic system, MAI-DxO, outperformed generalist physicians in diagnosing complex medical cases in a recent study. While the system shows promise for medical superintelligence, researchers noted that it still struggles to match the cost-efficiency and accuracy of specialized human teams.
Why it matters
The study demonstrates the rapid advancement of AI in specialized fields like medicine, though it highlights the current limitations in replacing human expertise.
Microsoft’s AI diagnostic system correctly diagnosed complex medical cases in a simulation more than twice as often as generalist physicians, according to a study published Thursday in Science. Mustafa Suleyman, Microsoft AI’s CEO, called the result a step toward “medical superintelligence.”
The system, dubbed MAI-DxO (DxO for short), coordinates several AI agents that act like a panel of doctors. They question a patient, order tests, and debate a diagnosis.
In a simulation using complex cases from the New England Journal of Medicine, it was correct 83% of the time. Primary care doctors and general internists, working individually with reference materials, were correct 36% of the time. One note: cases this complex are usually handled by specialists or physician teams, who weren’t part of the comparison.
