MedHELM is "a comprehensive healthcare benchmark to evaluate language models on real-world clinical tasks" created by a collaboration between, among others, Stanford's Center for Research on Foundational Models (CRFM) (Stanford - MedHELM). The question will be suspended on 28 May 2026 and the outcome determined using the ranks as reported by MedHELM at approximately 5:00p.m. ET on 29 May 2026 (Stanford - MedHELM Leaderboard, see "Mean win rate" on the "Accuracy" sheet tabbed near the top of the page; this page will be used for resolution). As of 5 February 2026, OpenAI's "GPT-5 (2025-08-07)" was ranked first with a score of 0.703, followed by OpenAI's "o4-mini (2025-04-16)" with a score of 0.697. In the event of a tie for first place by LLMs of different organizations, the LLM with the higher "Mean win rate" on the "Efficiency" sheet tabbed near the top of the page will be considered first. If the named source changes the way it presents the data, further instructions will be provided.
