This article provides a scientific–theoretical and analytical assessment of the efficiency indicators of artificial-intelligence (AI) based educational systems. The advantages of applying AI technologies in the learning process, their impact on students’ achievement levels, the opportunities for personalized (adaptive) learning, and the efficiency of teaching automation are examined on the basis of existing international meta-analyses. The influence of AI-based platforms on educational quality, learning dynamics and time efficiency is reviewed through statistical indicators, comparative tables and diagrams. The results obtained indicate that AI tools yield medium-to-high positive effects compared with traditional instruction.
