The European Commission published the final Code of Practice on marking and labelling of AI-generated content. The Code is voluntary and sets out practical steps to help providers and deployers of generative artificial intelligence (AI) systems meet the AI Act transparency obligations that will apply from 2 August 2026.

From that date, the AI Act will require clear labelling in key cases. Deepfakes and AI-generated or AI-manipulated text published on matters of public interest must be clearly labelled. Users must also be informed when they are interacting with an interactive AI system, such as a chatbot. These transparency requirements help people recognise when content has been generated or altered by AI, reducing the risk of deception and manipulation.

The Code was drafted by six independent experts, with input from over 180 stakeholders. Contributors included providers and deployers of interactive and generative AI systems and models, associations representing deployers, small and medium-sized enterprises, academia, the public sector and civil society organisations.

The Code consists of two sections:

Providers

This section focuses on obligations for providers of generative AI systems. It sets out how to ensure that AI-generated or AI-manipulated audio, images, video or text are marked in a machine-readable way and can be detected as artificially generated or manipulated.

Deployers

This section details obligations for deployers of generative AI systems. It explains how they must clearly label deepfakes and AI-generated or AI-manipulated text published to inform the public on matters of public interest when there has been no human review or editorial control.

These transparency rules complement the AI Act rules on general-purpose AI models and high-risk systems, supporting responsible development and use of AI in the EU.
