Microsoft Unveils MAI-DxO, AI System Outperforming Human Doctors in Disease Diagnosis

Microsoft Corporation (NASDAQ:MSFT) is one of the high profit margin stocks to buy now. On June 30, Microsoft announced an advancement in medical AI, revealing a new AI system called the MAI Diagnostic Orchestrator/MAI-DxO. According to Mustafa Suleyman, the CEO of Microsoft’s AI arm, this tool can diagnose diseases 4x more accurately and at a lower cost than a panel of human physicians.

The MAI-DxO system was tested using a Sequential Diagnosis Benchmark, comprising 304 diagnostically complex case studies sourced from the New England Journal of Medicine. The system works by mimicking a doctor’s step-by-step diagnostic process, querying several leading AI models such as OpenAI’s GPT (specifically the o3 model), Google’s Gemini, Anthropic’s Claude, Meta’s Llama, and xAI’s Grok. This chain-of-debate orchestration mechanism allows multiple AI agents to work collaboratively, emulating a virtual panel of physicians.

In the experiment, MAI-DxO achieved an accuracy of 80% (specifically 85.5% with the o3 model), while a group of 21 practicing physicians from the US and UK who worked without external resources achieved a mean accuracy of 20% on the same complex cases. Furthermore, the AI system reduced costs by ~20% by efficiently selecting less expensive tests and procedures.
