The tech giant poached several top Google researchers to help build a powerful AI tool that can diagnose patients and potentially cut health care costs.

Microsoft today announced an artificial intelligence tool that outperformed a panel of medical doctors in diagnosing complicated cases. The Microsoft AI Diagnostic Orchestrator (MAI-DxO) faced off against 21 experienced physicians from the U.

The new system is underpinned by a so-called “orchestrator” that creates virtual panels of five AI agents acting as “doctors”, each with a distinct role.
