With the rise of AI-powered language models, there has been growing interest in their creative and critical capabilities. In this study, we investigated ChatGPT generating and evaluating poetry. We conducted experiments to test ChatGPT's proficiency in categorizing and producing poems in various forms and styles. Our findings reveal distinctive linguistic patterns in ChatGPT-generated poetry, such as the prominent use of the first-person plural (“we,” “us,” “our”), as well as forms and styles that the model can identify with surprising accuracy. Our research contributes to a growing body of literature on AI-powered language models in the field of literature and poetry.
