EU AI Act Implementation and Global Regulatory Landscape 2025

European Union's Artificial Intelligence Act (AI Act) since its implementation began in March 2025, detailing its transition into an operational reality.

It outlines the risk-based regulatory framework, which categorizes AI systems from unacceptable to minimal risk, and highlights the crucial August 2025 milestone that activated rules for General-Purpose AI (GPAI) models and established the new governance bodies, including the European AI Office.

Furthermore, the text examines the multi-layered enforcement architecture, which coordinates the central AI Office with national competent authorities, using Italy's pioneering complementary law as a case study.

Finally, it contrasts the EU’s rights-based approach, which is driving a global "Brussels Effect," with the more fragmented, pro-innovation stance in the United States and China's state-directed, control-oriented "AI+" initiative.
