Feasibility of a Specialized Large Language Model for Postgraduate Medical Examination Preparation: Single-Center Proof-Of-Concept Study

PASS demonstrated strong user acceptance and grading reliability, suggesting feasibility in high-stakes examination preparation. Experienced learners could identify major hallucinations at comparable rates to examiners, suggesting potential in self-directed learning but with continued need for caution. Further research should refine grading accuracy and explore multicenter evaluation of specialized LLMs for postgraduate medical education.
