Abstract
The purpose of this study is to analyze the theoretical and legal foundations of the formation of the legal defi-nition of artificial intelligence (AI) in the context of its rapid development and implementation in various spheres of public life. The study examines the existing problems associated with the lack of a unified legal definition of AI, as well as analyzes approaches to its regulation applied in various countries and international organizations, including the European Union and the United States. The research methods used were the analysis of regulatory legal acts, scientific publications, as well as comparative legal analysis. As a result of the study, it was revealed that the lack of a unified legal definition of AI creates significant legal difficulties that hinder effective regulation of this area. It has been established that approaches to the definition of AI and its regulation differ significantly in different jurisdictions, which leads to conflicts and legal uncertainty. The need to develop agreed international standards and definitions of AI, as well as mechanisms for allocating re-sponsibility for harm caused by AI, and personal data protection was emphasized. In conclusion, the im-portance of an integrated and interdisciplinary approach to the development of a legal system capable of ef-fectively regulating relations related to AI is emphasized.
