On 574 retrospective cases from public database across eight pre-selected diagnoses, authors report it outperformed physicians on diagnostic accuracy and made largely guideline-concordant, medication-safe decisions. Every qualifier matters: sandbox on past records, text only; much edge on clear-cut test conditions; ordered about twice as many blood tests as doctors; several outcomes scored against original chart. Genuine advance agent that acts across whole workflow — not proof machine diagnoses better than doctor. Authors say generalization, safety and governance still need prospective real-world studies.
