About 190 organisations have signed the European Commission's Code of Practice on Transparency of AI-generated Content, just before the AI Act's rules on marking and labelling such content began to apply on 2 August 2026. Signatories include Google, Microsoft, OpenAI, Anthropic, Meta and Mistral, alongside deployers such as Lufthansa, Getty Images and Lenovo. The code stays open for signature, and two working groups on implementation start in September 2026.
What changed
The code had been assessed as adequate but no signatory count had been published.
