# EU AI Act transparency rules take effect, requiring companies to disclose synthetic content

> A major slice of the EU AI Act went live on August 2, and it changes what companies operating in Europe have to tell users about their AI. Systems that interact with people now have to disclose that they are AI, and any synthetic or manipulated media, including deepfakes, has to be labeled as artificially generated. There is also a watermarking requirement so that AI-made audio, images, video, and text carry machine-readable markers of their origin. The rules bite immediately for newly deployed systems, while tools already in the field get until December 2 to comply. Enforcement has teeth, with penalties reaching 15 million euros or 3 percent of a company's worldwide annual revenue, whichever is larger. For anyone building or shipping generative AI into European markets, this shifts transparency from a nice-to-have to a legal obligation, and it puts real pressure on the watermarking and provenance tooling that the industry has so far treated as optional. It also sets a template other regulators are likely to study closely.
