Microsoft's AI unit, led by Mustafa Suleyman, has developed an AI system that significantly outperforms human doctors in diagnosing complex health conditions. The system, using OpenAI's o3 model and a "diagnostic orchestrator," achieved over 80% accuracy on New England Journal of Medicine case studies, compared to 20% for human physicians. Microsoft emphasizes AI's role as a complement to doctors, not a replacement, despite calling it a "path to medical superintelligence."

Trending- 1 Microsoft's AI unit developed a new AI system for health diagnoses
- 2 The system was tested on over 300 NEJM case studies
- 3 AI system achieved over 80% accuracy, human doctors 20%
- 4 Microsoft announced the research on Monday
- 5 Research is being submitted for peer review
- 6 Microsoft acknowledges the system is not yet ready for clinical use
- Potential for radical change in healthcare

What: Microsoft announced an AI system that surpasses human doctors in diagnosing complex health conditions.
When: Announced Monday (June 30, 2025).
Where: Microsoft's AI unit (global, but research announced by British tech pioneer).
Why: To develop advanced diagnostic tools, potentially reduce healthcare costs, and explore the capabilities of AI in healthcare.
How: The AI system imitates a panel of expert physicians, using existing AI models (OpenAI's o3, Meta, Anthropic, Grok, Gemini) and a bespoke "diagnostic orchestrator" to take step-by-step measures for diagnosis. It was tested on over 300 interactive case challenges from the New England Journal of Medicine.
