First AI in history to score above 90% on the US Medical Licensing Exam

Developed as part of Mayo Clinic Platform Accelerate and powering Elsevier’s ClinicalKey AI, OpenEvidence is the only API to an AI purpose-built for the medical domain.

OpenEvidence scored 91% on the USMLE, ahead of Google Med-PaLM 2, Anthropic Claude 2, Chat GPT, and GPT-4.

Google Med-PaLM 2 Source: Google; GPT-4 Source: “Capabilities of GPT-4 on Medical Challenge Problems” ChatGPT Source: OpenAI. Claude 2 Source: Anthropic. Hippocratic AI’s self-reported value of 89.90% has been excluded since Hippocratic AI only took an unofficial, easier subset of USMLE practice questions; Hippocratic AI did not take (or at least report) scores for the official USMLE sample exam.
