This research introduces the GAI Marketing Model, a comprehensive conceptual framework for understanding and applying generative artificial intelligence (GAI) within marketing, specifically in the hospitality and tourism sectors. Building on existing classifications of GAI, this model incorporates critical elements such as adoption factors, marketing stages, and downstream outcomes. The framework offers a structured approach to exploring GAI’s potential to transform marketing strategies by enhancing personalization, improving customer engagement, and optimizing decision-making processes. The GAI Marketing Model synthesizes elements of technology, marketing theory, and consumer psychology, offering crucial insights that are instrumental for researchers and practitioners seeking to harness GAI for competitive advantage. Additionally, the model underscores the importance of ethical considerations and regulatory compliance, thereby ensuring that the integration of GAI into marketing practices remains both efficacious and responsible. This study establishes a foundational framework for future research, emphasizing the interdisciplinary scope of GAI’s influence on marketing strategies and practices
