Microsoft has taken \u201ca genuine step toward medical superintelligence,\u201d says Mustafa Suleyman, CEO of the company\u2019s artificial intelligence<\/a> arm. The tech giant says its powerful new AI tool can diagnose disease<\/a> four times more accurately and at significantly less cost than a panel of human physicians.<\/p>\n

The experiment tested whether the tool could correctly diagnose a patient with an ailment, mimicking work typically done by a human doctor.<\/p>\n

The Microsoft team used 304 case studies sourced from the New England Journal of Medicine to devise a test called the Sequential Diagnosis Benchmark. A language model broke down each case into a step-by-step process that a doctor would perform in order to reach a diagnosis.<\/p>\n

Microsoft\u2019s researchers then built a system called the MAI Diagnostic Orchestrator (MAI-DxO) that queries several leading AI models\u2014including OpenAI\u2019s GPT, Google\u2019s Gemini, Anthropic\u2019s Claude, Meta\u2019s Llama, and xAI\u2019s Grok\u2014in a way that loosely mimics several human experts working together.<\/p>\n

In their experiment, MAI-DxO outperformed human doctors, achieving an accuracy of 80 percent compared to the doctors\u2019 20 percent. It also reduced costs by 20 percent by selecting less expensive tests and procedures.<\/p>\n

“This orchestration mechanism\u2014multiple agents that work together in this chain-of-debate style\u2014that’s what’s going to drive us closer to medical superintelligence,\u201d Suleyman says.<\/p>\n

The company poached several Google AI researchers to help with the effort\u2014yet another sign of an intensifying war for top AI expertise<\/a> in the tech industry. Suleyman was previously an executive at Google working on AI.<\/p>\n

AI is already widely used in some parts of the US health care industry, including helping radiologists interpret scans. The latest multimodal AI models have the potential to act as more general diagnostic tools, though the use of AI in health care raises its own issues, particularly related to bias from training data that\u2019s skewed toward particular demographics.<\/p>\n

Microsoft has not yet decided if it will try to commercialize the technology, but the same executive, who spoke on the condition of anonymity, said the company could integrate it into Bing to help users diagnose ailments. The company could also develop tools to help medical experts improve or even automate patient care. \u201cWhat you’ll see over the next couple of years is us doing more and more work proving these systems out in the real world,\u201d Suleyman says.<\/p>\n

The project is the latest in a growing body of research showing how AI models can diagnose disease. In the last few years, both Microsoft and Google have published papers showing that large language models can accurately diagnose an ailment when given access to medical records.<\/p>\n

The new Microsoft research differs from previous work in that it more accurately replicates the way human physicians diagnose disease\u2014by analyzing symptoms, ordering tests, and performing further analysis until a diagnosis is reached. Microsoft describes the way that it combined several frontier AI models as \u201ca path to medical superintelligence\u201d in a blog post about the project today.<\/p>\n

The project also suggests that AI could help lower health care costs, a critical issue, particularly in the US. “Our model performs incredibly well, both getting to the diagnosis and getting to that diagnosis very cost effectively,” says Dominic King, a vice president at Microsoft who is involved with the project.<\/p>\n","protected":false},"excerpt":{"rendered":"Microsoft has taken \u201ca genuine step toward medical superintelligence,\u201d says Mustafa Suleyman, CEO of the company\u2019s artificial intelligence…\n","protected":false},"author":2,"featured_media":231077,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4316],"tags":[1942,5205,105,4348,3912,507,1318,16,15],"class_list":{"0":"post-231076","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-healthcare","8":"tag-artificial-intelligence","9":"tag-doctors","10":"tag-health","11":"tag-healthcare","12":"tag-medicine","13":"tag-microsoft","14":"tag-openai","15":"tag-uk","16":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114781752038836549","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/231076","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=231076"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/231076\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/231077"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=231076"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=231076"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=231076"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
