The European Commission's Code of Practice on Transparency of AI-generated Content has taken effect, supporting compliance with new AI Act transparency rules that became applicable on 2 August 2026.
The obligations, set out under Article 50 of the AI Act, require marking and labelling of AI-generated content, including deepfakes and certain AI-generated publications, to address risks of deception and manipulation. The code itself is voluntary, but the underlying Article 50 transparency requirements are legal obligations.
Drawn up by independent experts through a multi-stakeholder process facilitated by the AI Office, the code has two sections: one covering rules for providers on marking and detection of AI-generated and manipulated content, and one covering rules for deployers on labelling deepfakes and AI-generated or manipulated text. The Commission and the AI Board have confirmed the code as an adequate voluntary tool for demonstrating compliance.
Signatories can rely on the code's measures to show compliance, reducing administrative burden and providing legal certainty across EU member states. Those who choose other compliance routes must demonstrate adequacy individually to national market surveillance authorities. Signatories will also take part in Signatory Taskforces to share practices and advance implementation.
The EU claims that by the end of July 2026, around 190 companies and organisations had signed the code.
