Microsoft’s Mustafa Suleyman says its AI outperforms doctors on hard cases as he chases ‘medical superintelligence’
Microsoft’s new AI diagnostic system beat generalist doctors on hard cases, according to a study in Science. But most of the improvement seems to come from the AI models underneath, not from Microsoft’s system itself.
TL;DR
- Microsoft's AI diagnostic system, MAI-DxO, correctly diagnosed complex medical cases in simulations 83% of the time, compared to 36% for generalist physicians.
- The study indicates that the performance gains are primarily driven by advanced AI models such as OpenAI's GPT-5 and GPT-5.5, with MAI-DxO offering supplementary improvements.
- Microsoft is partnering with Mayo Clinic to develop a healthcare foundation model and with Beth Israel Deaconess Medical Center to evaluate MAI-DxO in real-world clinical settings.
- Mustafa Suleyman, CEO of Microsoft AI, aims for 'medical superintelligence,' believing AI capabilities in healthcare will improve significantly in the coming years.
- The MAI-DxO system coordinates multiple AI agents to question patients, order tests, and debate diagnoses, showing particular benefits in complex cases rather than emergency department scenarios.
