MedQA

GPT-4o May 2024 89.4% leads since Aug 2024 Dropped

Models answer multiple-choice questions from medical licensing exams, usually the 12,723-question English USMLE set. Scoring is accuracy.

The full dataset also has simplified and traditional Chinese exam sets.

In the authors’ words

Open domain question answering (OpenQA) tasks have been recently attracting more and more attention from the natural language processing (NLP) community. In this work, we present the first free-form multiple-choice OpenQA dataset for solving medical problems, MedQA, collected from the professional medical board exams. It covers three languages: English, simplified Chinese, and traditional Chinese, and contains 12,723, 34,251, and 14,123 questions for the three languages, respectively. We implement both rule-based and popular neural methods by sequentially combining a document retriever and a machine comprehension model. Through experiments, we find that even the current best method can only achieve 36.7%, 42.0%, and 70.1% of test accuracy on the English, traditional Chinese, and simplified Chinese questions, respectively. We expect MedQA to present great challenges to existing OpenQA systems and hope that it can serve as a platform to promote much stronger OpenQA models from the NLP community in the future.

GPT-4o leads with 89.4% among models released by May 2024

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in May 2024, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 GPT-4o May 2024 89.4%
  2. 2 phi-3-medium 14B 69.9%
  3. 3 phi-3-small 7.4B 65.4%
  4. 4 phi-3-mini 3.8B 53.8%
