10 June 2026 Article 50 Code update

The Code is voluntary. Article 50 is not. The European Commission published the Code of Practice on Transparency of AI-Generated Content on 10 June 2026. The Code supports provider marking under Article 50(2) and deployer labelling under Article 50(4), but Article 50 transparency obligations remain legal obligations where they apply.

Deployers should now record whether Code measures, EU icons, provider marking dependencies, label wording, first-interaction or first-exposure timing, accessibility, and public-interest text review were considered. Do not treat the Code, an icon, or a checklist as legal approval.

Article 50 timing watch

Article 50 generally applies from 2 August 2026. Article 111(4), as amended by Regulation (EU) 2026/1744, gives providers of systems covered by Article 50(2) that were placed on the market before 2 August 2026 until 2 December 2026 to comply with Article 50(2). This is not a transition for Article 50(4) or other Article 50 duties.

Regulatory update

Regulation (EU) 2026/1744 is in force. Separate Article 5 timing from high-risk application dates.

Regulation (EU) 2026/1744 was published on 24 July 2026 and entered into force on 27 July 2026. It moves many Article 6(2) / Annex III high-risk obligations to 2 December 2027 and Article 6(1) / Annex I product-integrated high-risk rules to 2 August 2028. Article 50 transparency, Article 4 AI literacy, Article 5 prohibitions and other near-term duties still require separate route-specific review. Continue inventory, role classification, vendor evidence, Article 50 trigger review and evidence-file preparation now.

Article 50 transparency obligations remain route-specific. Article 50 generally applied from 2 August 2026 for in-scope transparency duties. Article 111(4), as amended by Regulation (EU) 2026/1744, gives providers of certain Article 50(2) systems placed on the market before that date until 2 December 2026 to comply with Article 50(2). This tool separates provider and deployer routes; it is not a legal opinion.

Scope: Article 50 covers chatbots, deepfake/synthetic media generators, emotion recognition systems, and AI text generators on public-interest matters. Article 50 generally applied from 2 August 2026. Article 111(4), as amended by Regulation (EU) 2026/1744, creates a narrow transition until 2 December 2026 only for providers of certain Article 50(2) systems placed on the market before 2 August 2026. It is not a transition for Article 50(4) or other Article 50 duties.

Build a Route-Specific Article 50 Record

Select the legal route or routes that match the actual system or publication context. The tool then asks only the evidence questions relevant to those routes.

The output records findings, gaps, uncertainties, source basis, and provider dependencies. It does not calculate a compliance score.

Use the actual system and publication context. Provider marking and deployer labelling are separate routes.


Disclaimer: This assessment separates the Article 50 current-law routes from final non-binding Commission guidelines published on 20 July 2026 and voluntary Code measures reviewed on 2 September 2026. The Code supports Article 50(2) and (4) implementation but is not a universal control stack. This tool does not constitute legal advice. Consult qualified counsel for binding compliance decisions.

AI Content Marking Checker FAQ

What does AI Content Marking Checker help me check?
AI Content Marking Checker helps structure an initial EU AI Act Article 50 readiness check for marking, labelling, disclosure, and evidence-retention decisions. Treat the result as an internal working record for compliance, legal, privacy, security, or procurement review, not as a final legal determination.
Does this tool store my answers?
The tool is designed for browser-based use. Do not paste confidential, personal, regulated, client-sensitive, privileged, or production data into any free public tool.
What evidence should I retain after using this tool?
Retain the generated result, reviewer name, review date, AI system or vendor name, Article 50 scenario, label wording, label placement, provider marking dependency, EU icon decision, assumptions used, and any decisions that require legal, privacy, procurement, or security follow-up.
Is the Article 50 Code of Practice mandatory?
No. The Code is voluntary implementation support. Article 50 transparency obligations remain legal obligations where they apply. Use the Code to structure marking, labelling, evidence, and review workflows. Do not treat Code participation as a substitute for the AI Act, Commission guidelines, or legal review.
What changed on 10 June 2026?
The Commission published the Code of Practice on Transparency of AI-Generated Content. For deployers, the practical change is not a new standalone law. It is a clearer implementation reference for labelling deepfakes and certain AI-generated or manipulated public-interest text, plus evidence fields such as label wording, placement, icon consideration, and accessibility.
What is the difference between provider marking and deployer labelling?
Provider marking concerns machine-readable marking and detection for AI-generated or manipulated outputs. Deployer labelling concerns public-facing disclosure for deepfakes and certain AI-generated or manipulated text published to inform the public on matters of public interest. A deployer evidence file should show which side of that split was reviewed.
Do EU icons prove Article 50 compliance?
No. EU icons can support clearer labelling, but the deployer still needs a disclosure process. Record where the label appears, when the person sees it, whether it is accessible, what text accompanies it, and who approved the notice. Icon use alone should not be described as compliance proof.
