Abstract
ChatGPT is a natural language processing model that plays various roles, including providing information, answering questions, creative dialogue, language learning, and user engagement. However, there are limits to the accuracy and consistency of the information, and caution must be exercised in generating overly confident or inappropriate answers. Their understanding of emotions and context is also limited and may produce inappropriate content. Users should consult experts for expert information and important decisions.
