The European Union’s AI transparency regulation entered into force on August 2, requiring labels on all AI-generated or altered content. Developers must embed machine-readable markers in images, video, audio and text, and inform users when they are interacting with an artificial intelligence system. Non-compliance can trigger fines of up to €15 million or 3% of global annual turnover for large companies.

Labeling Requirements

Under the EU AI Act, developers of generative systems must embed machine-readable markers in all AI-created or altered images, video, audio and text. Services that interact directly with people must disclose that a user is communicating with artificial intelligence, unless this is obvious from the circumstances. Deepfakes must carry a visible label indicating AI manipulation. AI-generated texts on matters of public importance also require labeling, except when they have undergone human review or editorial oversight by a responsible legal entity.

Exemptions and Transition Period

Law enforcement agencies are granted limited exceptions from the rules on real-time biometric classification and emotion recognition. Artistic, satirical and fictional works are subject to a simplified disclosure procedure. Private individuals using AI solely for personal, non-professional purposes are not covered by the obligations. Systems placed on the market before the new rules took effect have a transition period until December 2 to implement technical marking and automated detection. Content generated before August 2 does not require retroactive labeling, although the Commission recommends voluntary marking where possible.

Penalties

National supervisory authorities can impose fines for non-compliance, with a fixed upper ceiling of €15 million. For large companies, the penalty may reach up to 3% of the previous financial year’s global turnover. When calculating fines for small and medium-sized enterprises, regulators must apply the principle of proportionality.
