Microsoft’s MAI‑DxO AI Beats Human Doctors on Complex Medical Cases
Current overview (not historical)
Microsoft’s MAI‑DxO system achieved an 83% diagnostic accuracy on a New England Journal of Medicine complex‑case simulation, far surpassing the 36% accuracy of general physicians. The AI also boosted GPT‑5.5’s performance from 72% to nearly 87% and raised Gemini 2.5 Flash’s accuracy from 46.4% to about 69%, with a slightly lower cost. The study, conducted jointly by Microsoft and Science magazine, highlights the potential of AI‑assisted diagnostics. Mustafa Suleyman, Microsoft’s chief AI officer, emphasized that the system’s performance represents a step toward “medical superintelligence,” though the findings remain preliminary and require further validation in real‑world settings.

- TechCrunch · AI · Oct 23, 02:43Microsoft’s MAI‑DxO AI System Outperforms Generalist Doctors on Complex Cases
Microsoft’s MAI‑DxO diagnostic system achieved an 83% accuracy rate on complex medical cases from the New England Journal of Medicine, more than twice the 36% accuracy of individual primary‑care physicians. The system orchestrates multiple AI agents that interview patients, order tests, and debate diagnoses, and it can reduce costs while improving accuracy when paired with models such as OpenAI’s GPT‑5 and GPT‑5.5.
