EU AI Act mandates AI-generated content labeling by December 2026

The EU AI Act mandates that generative AI systems, including text, image, audio, and video, must be marked to indicate their outputs are AI-generated. Systems already on the EU market before August 2, 2026, have a grace period until December 2, 2026, to implement this marking. New systems launched after August 2, 2026, must comply with the marking requirement from their launch date. AI

IMPACT This regulation will require AI developers and deployers to implement clear labeling for AI-generated content, impacting user trust and transparency in the EU market.
