Europe's AI Act Transparency and Labeling Rules Are Now in Effect

The European Union's AI Act transparency obligations have officially entered into force, requiring AI-generated content — including images, audio, video, and text — to be labeled as such, and imposing disclosure requirements on deepfake and synthetic media. Companies deploying AI-facing products in the EU must now implement technical mechanisms to mark AI-generated outputs and present disclosures to end users in a clear and accessible format. For developers shipping consumer or enterprise products in European markets, this is an immediate compliance requirement, not a future deadline. The rules also cover chatbots and AI-powered interaction systems, which must identify themselves as non-human when interacting with users. Teams should audit their product surfaces for AI-generated output and implement labeling pipelines before exposure to EU users.
