Source: Microsoft AI

Microsoft AI reported that its Diagnostic Orchestrator (MAI-DxO), a system that emulates a virtual panel of physicians working on top of language models, correctly diagnosed up to 85% of New England Journal of Medicine case records, more than four times the rate of a group of experienced physicians, and did so more cost-effectively.

Why it matters

Health systems weighing diagnostic AI got a benchmark built on real case records, though Microsoft notes the physicians worked without colleagues, textbooks or generative AI.
