Generative artificial intelligence (AI) has evolved rapidly and is impacting many fields. Since the release of ChatGPT, a large language model in November 2022, it's impact on higher education has attracted significant attention. ChatGPT's main applications include information retrieval, automatic summarization, writing assistance, language translation, and dialogue systems. However, concerns have been raised regarding the learning process and outcomes of students, the authenticity, originality and integrity of academic works and publications. The authenticity of content generated by AI need to be attended because the natural language generation models are capable of creating "hallucinations", referring to mistakes in the generated text that people believe to be true. It takes tremendous efforts to verify the results generated by AI models. The National Taiwan University has adopted an open attitude towards AI as a tool to enhance teaching and learning. The university advise teachers to adjust course assessments, students to understand how the tool works, verify the content it generates, and using it as a starting point to form their own opinions rather than simply accepting the results. The use of technology in medical education has accelerated overwhelmingly. Medical teachers are facing a transition from being knowledge distributers to continuous learner. These innovations will lead to the development of new paradigms for learning and teaching. With the technology improvement, we should keep medical humanities in center. Further research on the impact of generative AI in medical education is anticipated.
