Microsoft AI developed a sequential diagnosis benchmark (SD Bench) using 304 NEJM cases and an orchestrator (MAI-DxO) that combines multiple language models. The best-performing combination of MAI-DxO with OpenAI's o3 achieved 85.5% diagnostic accuracy, outperforming the 20% mean accuracy of experienced physicians.

## 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.
