Microsoft AI introduced the Sequential Diagnosis Benchmark (SD Bench) based on 304 NEJM case records and the Microsoft AI Diagnostic Orchestrator (MAI-DxO). MAI-DxO paired with OpenAI's o3 achieved 85.5% diagnostic accuracy, compared to a mean accuracy of 20% among 21 experienced physicians. The orchestrator is model-agnostic and designed to emulate a virtual panel of clinicians.

## Evidence

Verbatim from https://microsoft.ai/news/the-path-to-medical-superintelligence/:

> The best performing setup was MAI-DxO paired with OpenAI’s o3, which correctly solved 85.5% of the NEJM benchmark cases. For comparison, we also evaluated 21 practicing physicians from the US and UK, each with 5-20 years of clinical experience. On the same tasks, these experts achieved a mean accuracy of 20% across completed cases.
