Just published @ScienceMagazine Higher medical accuracy at lower cost A 3-agent AI for sequential diagnosis nearly doubled accuracy compared with physicians for >300 @NEJM CPC cases and >300 ER cases AND substantially lowered cost, also exceeded performance of many AI models, physicians plus AI @HarshaNori @erichorvitz @Dominic1King @mustafasuleyman

Our paper is out in @Cancer_Cell! We started this project almost 5 years ago with the idea that to understand why some cancer patients respond to immunotherapy and others do not, we may need to look beyond the tumor before treatment. Immunotherapy is not just a test of a pre-existing state; it is a perturbation. It changes the tumor immune microenvironment. So the question became: can the direction of that change explain response? authors.elsevier.com/a/1niWC…
