A set of best practices to help ensure better compliance with the transparency obligations under the Artificial Intelligence Act, which will come into force on 2 August. Accordingly, the European Commission today, Wednesday 10 June, gave the go-ahead for the publication of the code of good practice on the marking and labelling of AI-generated content. The code is voluntary and sets out concrete measures to assist both providers and operators of generative artificial intelligence systems.

Aiming for transparency

From 2 August 2026, the date on which the rules and obligations introduced by EU Regulation 2024/1689 will come into full effect, the AI Act will require clear labelling for certain particularly sensitive content, such as deepfakes and texts generated or manipulated by AI and published on matters of public interest. Users must also be clearly informed when they interact with a interactive AI system, such as a chatbot.

This set of guidelines, based on transparency, has a specific aim: to help people recognise when content has been generated or modified by artificial intelligence, so as to reduce the risk of deception, manipulation, disinformation or inaccurate information.

The code

The code was drawn up by six independent experts , with input from over 180 stakeholders, including providers and operators of interactive and generative AI systems and models; associations representing operators; small and medium-sized enterprises; the academic community; the public sector; and civil society organisations.

The Code consists of two sections: suppliers and distributors. The first section focuses on the obligations that suppliers of generative artificial intelligence systems must comply with. It sets out how they must ensure that audio, images, video or text generated or manipulated by AI are labelled in a machine-readable manner and can be recognised, identified and understood by all users as having been artificially generated or manipulated. The second section is devoted to the obligations of distributors of generative AI systems. It explains how they must clearly label deepfakes and AI-generated or AI-manipulated text intended to inform the public on matters of general interest, particularly where there has been no human review or editorial oversight.

These transparency rules supplement those of the AI Act on general-purpose artificial intelligence models and on high-risk systems. The European Commission’s aim, in fact, is the responsible development and use of this innovation within the European context, even at the risk of falling behind the United States and China in this regard. ‘European citizens have the right to know whether what they see, hear or read has been created or modified by artificial intelligence, especially when such content can influence and shape the public debate. Transparency is how we protect trust,” comments Henna Virkkunen, Executive Vice-President for Technological Sovereignty, Security and Democracy. “We call on providers and operators to sign up to the code and to show leadership in the development and implementation of responsible and trustworthy AI.”

Launching on 2 August

The code is now open for signatures from all interested parties and will be further supplemented by the Commission’s guidelines, which are intended to clarify the scope of the legal obligations and address aspects not covered by the code. The guidelines will, for the most part, be practical in nature, designed to help suppliers and distributors meet the requirements for transparency. Those who sign it will thus be able to demonstrate compliance with the obligations under the AI Act, which will come into force on 2 August.
