Abstract	Generative AI technologies like ChatGPT have rapidly gained global attention, yet research on their practical applications and user perceptions remains limited. This study addresses these gaps by investigating the factors that influence ChatGPT usage, aiming to enhance the development and adoption of generative AI services. ChatGPT’s characteristics are categorised into information, service, and personal dimensions. Empirical analysis shows that integration and timeliness positively impact perceived usefulness and ease of use, while accuracy does not significantly affect either factor. Convenience enhances perceived ease of use but not usefulness, while compatibility unexpectedly exerts a negative effect on perceived usefulness. Playfulness strongly increases perceived usefulness, whereas self-efficacy unexpectedly reduces it. Differences between experienced and inexperienced users are also identified, offering deeper insights into user behaviour. By clarifying the key drivers and barriers to ChatGPT acceptance, this study provides important academic contributions and practical strategies for developers and organisations seeking to maximise the potential of generative AI technologies.
