Microsoft has introduced a medical AI system that diagnoses like a panel of expert doctors. It combines top AI models to analyze complex cases through collaborative debate.

Tested on 304 challenging cases, it achieved 85% accuracy—far above the 20% score of human doctors—while cutting diagnostic costs by 20%. This signals a major leap toward AI-powered medical decision-making.

AI Diagnoses With 85.5% Accuracy

Microsoft’s AI system tackles medical cases by simulating a group of expert doctors debating diagnoses. In the following post, it’s shown how the system blends GPT-4, Gemini, and Claude to collaborate on complex cases before delivering a final judgment:

Tested on 304 cases from the New England Journal of Medicine, it achieved 85% accuracy—compared to 20% for human doctors on the same problems.

Its structured reasoning approach offers expert-level support in diagnostics, especially in areas lacking medical specialists.

Cutting Healthcare Costs By 20%

The AI system doesn’t just improve accuracy—it also reduces costs by about 20%. It mimics how real medical teams decide which tests are necessary, avoiding extra scans and procedures.

In the tweet below, it’s shown how the system achieves this efficiency through collaborative reasoning across multiple AI models:

By focusing only on essential diagnostics, it prevents redundant testing and shortens hospital time. This means fewer follow-ups and less spending overall.

Its precision-first strategy helps make healthcare smarter, faster, and more affordable.

A Step Toward Medical Superintelligence

Microsoft’s AI, called MAI-DxO, combines models like GPT-4, Gemini, and Claude to act as a virtual team of five expert agents. In the tweet below, a doctor highlights how each AI model plays a specialized role—from choosing tests to managing costs and challenging diagnoses:

This system achieved 85% accuracy and reduced diagnostic spending by 20% in testing against published cases from medical journals.

Although not yet in clinical use, its team-based structure signals a bold step toward medical superintelligence.
