# EU AI Act enforcement begins August 2, 2026 with transparency requirements

> As of today, August 2, 2026, most of the remaining provisions of the EU AI Act come into force, marking the moment the bloc's landmark rulebook shifts from theory to enforcement. The headline change is Article 50's transparency regime, which targets systems that can create risks for ordinary people. In practice that means AI generated content will need to be labeled, and chatbots will have to disclose that users are talking to a machine rather than a person. A recent Digital Omnibus agreement pushed some of the tougher high risk obligations and regulatory sandbox requirements out to 2027, softening the immediate blow for companies. The timing is notable because Europe is not moving alone. A California transparency law also becomes operative this month, meaning firms building or deploying AI now face converging disclosure rules on both sides of the Atlantic. For anyone shipping generative features, labeling is no longer optional.
