# EU AI Act Enforcement Begins: Transparency Requirements Take Effect

> As of August 2, 2026 the European Union began enforcing the transparency layer of its AI Act, and the practical effects are immediate. Chatbots now have to tell users they are talking to a machine, deepfakes and AI-altered media have to be labeled, and AI-generated content needs machine-readable markings so it can be detected downstream. The high-risk provisions of Annex III, including conformity assessments and CE marking, are in force as well. The teeth are financial: violations can draw penalties of up to 15 million euros or 3 percent of worldwide turnover, whichever is larger. That is enough to make compliance a board-level concern rather than a legal footnote, and companies are already moving. Anthropic, for one, has started watermarking Claude output for EU deployments. What makes this significant is that it turns a lot of long-running debate about AI disclosure into concrete obligation. The rules will not settle every argument about what counts as an AI system or how robust a watermark has to be, but they set a baseline the rest of the world will be watching and, quite possibly, copying.
