About 190 organisations signed the European Commission's Code of Practice on Transparency of AI-generated Content before the AI Act's marking and labelling duties began applying on 2 August 2026. The code sets out measures for companies that build generative AI systems and for those that use them, and has been judged adequate by the Commission and the AI Board. Signing is voluntary and the legal duty itself falls only on providers; the list stays open and two working groups start in September 2026.
What changed
Marking and labelling of AI-generated content had no agreed compliance route ahead of the AI Act deadline.
