Microsoft’s Mustafa Suleyman says its AI outperforms doctors on hard cases as he chases ‘medical superintelligence’

A study published Thursday in Science found that Microsoft's MAI-DxO system, which coordinates several AI agents acting like a panel of doctors, correctly diagnosed complex New England Journal of Medicine cases 83% of the time in a simulation, versus 36% for primary care doctors and general internists working individually with reference materials. Microsoft AI CEO Mustafa Suleyman called the result a step toward "medical superintelligence," and the company is working with the Mayo Clinic on a healthcare foundation model planned for next year and with Beth Israel Deaconess Medical Center to evaluate DxO's clinical reasoning in real hospital settings.
