Europe regulates the model class with the AI Act, in full force since August 2025, carrying a maximum penalty of thirty-five million euros or seven percent of global turnover. The United States has no federal horizontal statute; California, Colorado, and Texas are doing the load-bearing work. China regulates the output — synthetic-content watermarking has been mandatory since September the first, 2025, enforced by the cyberspace administration with administrative penalties and licence revocation. Convergence on principle, divergence on implementation. A model deployed globally now ships three compliance bundles, not one. |
