Microsoft's MAI-DxO in Science: twice as accurate as doctors on hard cases
Microsoft AI published a study of its MAI-DxO diagnostic system in Science on 22 October; the system diagnoses sequentially using multiple AI agents, like a medical panel. Reports say it reached 83% accuracy on simulated complex cases against 36% for human doctors, and Mustafa Suleyman presents it as a step towards medical superintelligence.
Who is affected and how
- doctor
- Results on simulated cases are not yet clinical evidence, so it is worth comparing the sequential, question-asking and test-ordering approach with your own differential diagnosis workflow.
- health IT
- The multi-agent, panel-like architecture is a new pattern for diagnostic support, and integration and validation plans will need to be prepared for it.
- health policy
- Because these systems are said to outperform doctors, clinical validation and liability frameworks need to be developed first.
