The rapid development of generative artificial intelligence, especially ChatGPT, is bringing noticeable changes to Human Resource Development (HRD) practices. Organizations are increasingly using AI-based tools to improve training programs, employee learning, and performance support systems. This study examines how ChatGPT can assist HR professionals in creating learning content, supporting personalized skill development, and enhancing employee engagement. The research is conceptual in nature and is based on a review of existing academic and industry literature. The findings suggest that ChatGPT improves access to learning resources and reduces the administrative burden of HR teams. However, concerns related to information accuracy, ethical use, data privacy, and over-dependence on technology must be carefully managed. The study highlights the importance of combining AI capabilities with human supervision to ensure responsible and effective implementation. Overall, ChatGPT can strengthen HRD practices when used as a supportive tool rather than a replacement for human expertise.
