European Commission publishes final-version Code of Practice on AI-generated content marking — June 2026 finalization sets August 2 implementation framework
The European Commission published the final version of the Code of Practice on marking and labelling of AI-generated content in June 2026, on the timeline the Commission committed to earlier in the year. The Code provides the implementation framework for Article 50 deployer-side obligations landing August 2, with technical guidance on C2PA-style provenance metadata embedding.
The substantive piece is the implementation-framework specificity. The Code of Practice provides the technical guidance that turns Article 50's broad transparency requirements into concrete implementation patterns — what counts as machine-readable marking, what counts as deployer-side labelling, what disclosures suffice for content placed on the EU market. For tool vendors (Adobe, Microsoft, Canva, plus the open-source content-creation tool stack), the Code is the operational reference.
The bifurcation between the Code's deployer-side guidance and the AI Omnibus December grace period for model providers is now formalized. Tool vendors building content-creator UIs need to ship marking-enabled exports by August 2 regardless of whether the upstream models are grandfathered or fresh — which means the Code's technical guidance has more near-term operational relevance than the Omnibus grace period for the broader deployment ecosystem.
