Artificial intelligence (AI) is increasingly used in creative domains, including dance. This article focuses on the ‘Prompt Dancer’ project, an experimental collaboration between OpenAI’s ChatGPT-4 and professional dancers to co-create a dance choreography. We describe and analyze the process of this dancer–AI co-creation, examining how the ChatGPT-4 generative model functioned as an AI choreographer and how human dancers interpreted and adapted its prompts. A practice-as-research methodology was adopted to capture emergent insights from the creative process. The findings shed light on the potential and limitations of using a conversational AI for choreographic creation, illustrating new modes of human–AI creative partnership as well as challenges such as communication gaps and conceptual biases. This study contributes to the growing discussion on AI in the performing arts by providing empirical observations of dancer–AI interaction and reflecting on the implications for future creative practice.
