While ChatGPT and other Large Language Models (LLMs) show promise in medical education, several areas require further exploration. We emphasize the importance of using larger question sets and diverse formats, such as multiple-choice questions (MCQs), where ChatGPT has demonstrated more consistent performance in prior studies. Additionally, improvements in artificial intelligence (AI) models and the incorporation of updated anatomical databases could enhance response accuracy. The study also identifies ChatGPT's lack of anatomical specificity as a limitation, which may be addressed by training AI models on specialized anatomy datasets.
