Thanks! Glad that you like it:)

We haven't trained or fine-tuned on neither of USMLE or MedQA. We use several LLMs in our system, and honestly I don't think there is any single thing that I can point to which is different to how other people do it. I guess it's a combination of many small improvements.

Sorry for the vague answer. We are thinking about publishing a report at some point.
