Open Evidence is AI for clinicians, trained on medical data and with direct access to text in major journals like JAMA and NEJM. I understand it's free registration if you have an NPI.
Press release, that Open Evidence gets a perfect 100% on the US Medical Licensing Exam, USMLE.
A competing general model, GPT 5, got 97%.

I don't have an NPI and haven't used OpenEvidence directly. I've used Scite.ai, which is based on PubMed plus many open access journals.
