CWI contributes to EU guidelines for marking and labelling AI-generated content

The European Commission has recently published the final Code of Practice on Transparency of AI-Generated Content. This code is a key instrument in supporting the transparency obligations for providers and deployers (i.e., users) of generative AI systems, as part of the European AI Act. For providers, the Code of practice offers rules for marking and detection of AI-generated and manipulated content. For users, the code has created rules and a set of icons that they can use to label their AI-generated content, including deepfakes and certain AI-generated text.

Abdallah El Ali from CWI’s Distributed & Interactive Systems (DIS) group actively took part in the drafting process of the rules for Disclosure of Deepfakes and Certain AI-Generated Text for Deployers. He contributed especially to discussions on disclosure of AI-generated content from a Human-Computer Interaction lens. In doing so he emphasizes the importance of visualizing the nuances of human-AI collaboration in AI disclosures. This contribution connects closely to his work leading the DIS group’s research area on trustworthy human-AI interaction, where he investigates AI disclosures, LLM evaluation biases, and the design of transparent, human-centered AI interfaces. You can read more about Visualizing Human-AI Collaboration in his paper contributed to the CHI’26 conference and on the DIS-website. This line of work is often carried out in collaboration with the AI, Media and Democracy lab, whose co-founder Prof. dr. Natali Helberger (University of Amsterdam) also contributed to the Code of Practice.

A Milestone for the EU AI Act

The Code was drafted by six independent experts and developed through a stakeholder process coordinated by the European AI Office. This process involved over 180 participants across working group meetings, interactive workshops, feedback rounds, and support channels. It is intended to help providers and deployers prepare for the AI Act transparency rules, which will strictly apply from 2 August 2026.
