OpenAI models sweep medical QA accuracy top spots, GPT-6.1 Sol hits 96.7% on MLCR-AA

ArtificialAnlys · x · 2026-10-21

On Artificial Analysis' MLCR-AA leaderboard, OpenAI models hold the top accuracy scores, led by GPT-6.1 Sol (max) at 96.7% and GPT-6 Astra (max) at 95.6%; the best non-OpenAI model is Qwen3.8 2.4T A95B at 76.1%.

Accuracy means no claim contradicts the medical record, from dates and measurements to finding severity. But OpenAI models often miss key points the question asks for — GPT-6.1 Sol (max) is complete on only 40.0% of questions.
