EU transparency code for AI-generated content signed by 190 signatories
Around 190 organisations have signed the European Commission’s voluntary Code of Practice on Transparency of AI-generated Content ahead of new AI Act transparency obligations taking effect on 2 August 2026. The code provides guidance on how providers and deployers of generative AI systems can comply with legal requirements for labelling AI-generated content.
The European Commission announced that approximately 190 organisations had signed the voluntary Code of Practice on Transparency of AI-generated Content by the end of July 2026, ahead of the AI Act’s transparency obligations entering into application on 2 August 2026.
The code was developed by independent experts and assessed by both the European Commission and the AI Board. It provides practical measures to help organisations comply with legal obligations requiring certain AI-generated content to be marked and labelled. According to the Commission, the framework is intended to offer a more predictable approach to demonstrating compliance across EU member states.
The code is divided into two sections covering different categories of organisations. One section is aimed primarily at providers of generative AI systems, while the other applies to deployers of such systems. Providers of AI models and technologies that support content marking and detection may also sign the first section.
According to the Commission, the signatories represent a wide range of sectors, including information technology, telecommunications, education and retail. Around half of the participating organisations are described as small or recently established companies. The Commission stated that this reflects the diversity of the AI ecosystem and that the code is designed to support compliance for organisations of different sizes, including small and medium-sized enterprises.
Among the organisations that have signed the section for providers are companies including Aleph Alpha, Anthropic, Black Forest Labs, Cohere, Google, Meta, Microsoft, Mistral, OpenAI and Synthesia. Organisations signing the deployers’ section include Bulgari, Fastweb, Getty Images, Iberdrola, Lenovo and Lufthansa.
The Commission noted that participation in the code remains voluntary and that organisations can continue to join after the AI Act’s transparency obligations begin to apply. Signatories will also be invited to participate in two task forces launching in September 2026 to exchange implementation experiences, share industry practices and provide feedback on the application of the code.
