Microsoft reported 83% diagnostic accuracy over 304 retrospective complex cases. The reported clinician comparison used a smaller 56-case subset; patient benefits are unproven.
Important limit: The 304-case evaluation and the 56-case physician subset must not be treated as equal comparison samples.
Evidence timeline
Microsoft described sequential-diagnosis benchmarks and its diagnostic orchestrator.
The different evaluation denominators and prospective validation limits were documented.
