EU AI Content Labeling Rules Take Effect August 2, With December Deadline for Existing Systems

New European Union transparency rules will require companies to label AI-generated or AI-altered content, including chatbot responses, images, audio, and video, starting Sunday, August 2. Companies operating in the EU must use both visible labels and technical markers, such as watermarks or embedded metadata, to identify synthetic material. Existing AI systems must comply by December 2, after which enforcement will increase and significant fines may be imposed.
