Microsoft has developed a diagnostic AI system called MAI-DxO that reportedly outperformed human physicians in a simulated medical case study. The AI achieved an 83% success rate on challenging cases from The New England Journal of Medicine, compared to 36% for doctors. MAI-DxO functions as a virtual panel, with multiple AI agents proposing diagnoses, selecting questions, and challenging each other, while also considering costs. While the system utilizes OpenAI's GPT-5 model, Microsoft's unique panel approach added further improvements, though real-world testing is still pending. AI
