ChatGPT provides different answers to similar questions based on the prompts, and patients may not have expertise in prompting ChattPT to elicit a best answer. (Prompting large language models has been shown to be a skill that can improve). Of greater concern, ChatGPT fails to provide sources or references for its answers. At present ChatGPT cannot be relied upon to address patient questions; in the future, ChatGPT will improve. Today, AI requires physician expertise to interpret AI answers for patients.
