Microsoft says its new AI tool performs four times better than experienced human doctors in diagnosing complex health conditions – but the company’s CEO says that human doctors are still required to help treat diseases.
“Title” in a paper released on MondayMedical Superintending path“Microsoft introduced an AI tool, in which up to 85% complex cases were correctly diagnosed and more cost-effectively than human physicians.

The team used more than 300 complex case studies from the New England Journal of Medicine (NEJM) and the AI Tool copied a panel of doctors to find the right diagnosis. The AI Tool asked the questions of the data, recommended what testing the imaginary patient should do, and reached a diagnosis as it learned more information. As researchers added more data to the AI Tool, it updated its best estimate of diagnosis in real time and explained the logic behind its conclusion.
Researchers at Microsoft stated that the AI tool “solved” more than eight of the 10 Nejm case studies – the average success rate of two out of 10 is much better for human physicians. AI also ordered less imaginary tests to reach the correct diagnosis, making it more cost effective than a human physician.
Human doctors are usually characterized by width, like a normal family physician, or depth, like a specialist. The team stated that the AI Tool demonstrated the “clinical argument capabilities”, which is “more than any individual physician”, as it has the ability to combine both width and depth of expertise.
The AI tool is not yet ready for clinical use and will be approved only after safety testing and clinical verification. However, Microsoft AI CEO Mustafa Suleman says that it can help Microsoft to provide “high-quality” health advice in response to 50 million health related questions obtained every day through their copillot AI assistant and bing search engine.
“Although this is just initial research, we are expecting that as we get it in production, it will provide everyone access to very high quality health information,” Suleman said. Yahoo! finance On Monday.

Suleman said that the AI tool examines the existing medical information, synthesizes it, and gives it back to humans at the right time – but it still needs human doctors that is to make it accountable. Doctors also need to plan and maintain treatment after diagnosis.
“You definitely need your doctor,” Suleman told the outlet, saying that the AI Tool will probably roll out “in partnership with doctors themselves.”
