OpenEvidence released three medical AI search models to verified clinicians at no cost, rolling them out through its website and mobile apps. The company says Osler is its default, faster model; Sackett is designed for deeper evidence searches; and Snow runs longer literature investigations before producing a report. A fourth model, Darwin, is available only to researchers through an application process. OpenEvidence attributes that restricted access to dual-use concerns involving frontier biomedical reasoning.
