This paper identifies the most frequently cited features in existing definitions of agentic AI and AI agents, examines how these features are described across sources, and maps them to the key elements of the OECD definition of an AI system. By highlighting both shared traits and differences, the paper aims to support clearer conceptual understanding and inform future research and policymaking. It also provides descriptive data on recent trends in the uptake of AI agents and agentic AI.
