Which AI is best at differential diagnosis?

Given a full patient picture — history, labs, meds, wearables — which model builds the most credible differential and orders the right workup next? Licensed clinicians judge that exact question blind, on real de-identified charts.

The question every model answers: “Given this patient's full picture, what differential diagnoses should be considered, in order of likelihood? What workup would you order next, and what red flags would change your thinking?
