The European Commission published on 10 June 2026 the final version of the Code of Practice on Marking and Labelling of AI-Generated Content, provided for under Article 50 of the AI Act. The document, a code of good practice on the marking and labelling of AI-generated content, represents the outcome of eight months of work involving dozens of meetings, workshops and bilateral discussions with more than 200 stakeholders and representatives of the 27 European Union Member States.
Two working groups, composed of experts in technology, law and the social sciences, contributed to defining a framework aimed at preventing deception and manipulation related to synthetic content and strengthening public trust in the digital ecosystem.
Professor Dino Pedreschi of the University of Pisa served as Vice-Chair of Working Group 1: Transparency Obligations Applicable to Providers of Generative AI Systems, which was tasked with developing guidelines on the transparency and recognisability of content generated by generative artificial intelligence systems. In this work, he was supported by Virginia Morini, a postdoctoral researcher in the Department of Computer Science at the University of Pisa, and Daniele Gambetta, a PhD candidate in the National PhD in Artificial Intelligence for Society, coordinated by the University of Pisa.
“Coordinating this work was a complex but fascinating experience,” says Dino Pedreschi. “We now hope that many stakeholders will adhere to the Code and that it will make an effective contribution to the fight against misinformation and disinformation by gradually making it possible to distinguish between human- and AI-generated content online. An important aspect is that this work has already inspired similar legislative initiatives in different parts of the world, particularly in California, where we are collaborating with local lawmakers.”
“Already on 11 June,” Pedreschi concludes, “OpenAI announced its support for the initiative, describing it as a useful tool for fostering an innovative and trustworthy European AI ecosystem.”
