OpenEvidence Released Osler, Sackett and Snow Free on 3 September 2026 and Gated Darwin on Dual-Use Grounds: What a Perfect Score on 660 MedQA Questions Shows

Quentir Medicine Monitor

Evidence-based insights for quantum medicine.

OpenEvidence assigns its quickest model about five seconds per answer and its deeper modes thirty seconds and five minutes, and on 3 September 2026 the Miami company, whose search tool is used by a majority of US physicians on its own account, split its product along that line. Three models that differ in how long they think were released free to every verified clinician, and a fourth, described as its most capable, is one a researcher must apply to use. The company's stated reason for the fourth is that a model able to reason at the frontier of virology, immunology and human genetics could also, in the wrong hands, accelerate work the world tightly governs.

The release names Darwin as the withheld model and reports that it answered a physician-cleaned set of 660 MedQA questions without a single error, along with 72.8 percent on MedXpertQA, 82.7 percent on HealthBench Professional and 87.2 percent on the NOHARM harm benchmark. The dual-use rationale is stated in one sentence and the access rule in another, and the company has published its annotations and its model's full outputs for the four benchmarks. This Monitor reads what the 660 questions and the other three scores can support, how the company chose the comparators and the judge, and what the access decision looks like beside the framework the founder of this site published for exactly this kind of choice.
