European Union: European AI Office announced drafting of Code of Practice on Transparent Generative AI Systems

On 4 September 2025, the European AI Office opened a call for expression of interest to participate in the process of drawing up the first Code of Practice on Transparent Generative AI Systems, with submissions due by 2 October 2025. The Code of Practice aims to detail how providers and deployers of generative AI systems can comply with their transparency obligations laid down in Article 50(2) and (4) of Regulation (EU) 2024/1689 (the AI Act). These obligations, which will become effective on 2 August 2026, require AI providers to design and develop AI systems so that AI-generated or -manipulated content is detectable through machine-readable marks. Additionally, deployers are required to visibly label deep fakes or AI-generated or -manipulated text published with the purpose of informing the public of public matters, unless the content has been subject to human review or editorial control and a person holds editorial responsibility for its publication. The Code will facilitate the effective implementation of these transparency obligations, supporting practical arrangements for detection mechanisms and cooperation along the value chain to enable the public to distinguish AI-generated content and reduce risks of deception, manipulation, and misinformation.
