Article 50 Transparency Evidence Validator

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's operational sections address Article 50(2) provider marking and Article 50(4) deployer labelling. Article 50(5) supplies the cross-cutting requirements for clear, distinguishable and accessible information at the latest at first interaction or exposure. The Code remains voluntary implementation support; Article 50 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

Under the current AI Act, Article 50 transparency obligations generally apply from 2 August 2026. The Commission's Code Q&A describes a transition until 2 December 2026 for AI systems placed on the market before 2 August 2026 that fall within Article 50(2) or (4). The Council-adopted Digital Omnibus amendments should not be treated as in-force law until Official Journal publication and entry into force are verified.

Regulatory update

Current law remains operative until OJ publication and entry into force. The Council-adopted Digital Omnibus text is a provisional planning track.

The 29 June 2026 Council-adopted Digital Omnibus text would postpone many Annex III high-risk AI obligations to 2 December 2027 and product-integrated high-risk AI rules to 2 August 2028 once published in the Official Journal and in force. Article 50 transparency, AI literacy, prohibited-practice, and other 2026 duties still require separate review. Continue inventory, role classification, vendor evidence, Article 50 trigger review, and evidence-file preparation until Official Journal publication and entry into force confirm the amended schedule.

Article 50 does not impose one universal three-layer test on every organisation. The relevant evidence depends first on whether the organisation is a provider under Article 50(2), a deployer publishing content under Article 50(4), both, or still uncertain about its role.

Use this local-browser tool to record machine-readable marking evidence, detection and transformation testing, and human-facing disclosure evidence without converting those controls into a compliance score.

Current-law and Code status

Article 50(2) requires providers of relevant synthetic-content AI systems to ensure outputs are machine-readably marked and detectable. Article 50(4) requires deployers to disclose deepfakes and qualifying public-interest text, subject to the statutory treatments and exceptions. Article 50(5) supplies cross-cutting clarity, timing and accessibility requirements.

The 10 June 2026 Code is voluntary implementation support. Its operational sections address provider marking and detection and deployer labelling. EU icons, C2PA, metadata and watermarking can support an evidence route, but no single method or icon proves compliance by itself.

Transformation and persistence risk

Re-encoding, compression, cropping, screenshots and platform processing may remove or weaken some provenance signals. Test the actual distribution channels and document limitations rather than assuming that metadata, a watermark or a visible label will always survive.

Review the evidence for one content pipeline

Generate a role-aware internal record. The output identifies evidence gaps and dependencies; it does not return a percentage score or legal conclusion.

Privacy by design: This executes in the browser. Do not enter confidential, personal, privileged or production data.

1. Pipeline context and role

Content engine / campaign ID

Primary Article 50 role

2. Machine-readable marking evidence

For provider routes, record the current marking implementation. For deployer-only routes, this is provider or vendor dependency evidence.

No verified marking evidence

No machine-readable marking evidence has been obtained or tested.

Limited or proprietary marking

Basic metadata or vendor-specific signals exist, but interoperability, reliability or modality coverage is incomplete.

Documented machine-readable implementation

The selected method and technical-feasibility limits are documented and tested. C2PA or another standard may be used, but is not mandatory by name.

3. Detection and transformation testing

Record whether the artificial origin can be detected and how the signals behave after realistic transformations.

No detection route or testing

No detector, verification method or transformation test has been documented.

Limited detection evidence

Detection works in some scenarios, but coverage or resilience is incomplete.

Tested detection and limitations record

Detection and transformation results are documented across the relevant content types and channels.

4. Human-facing disclosure evidence

For deployer Article 50(4) routes, record the label or disclosure shown at publication or first exposure.

No disclosure evidence

No visible or audible disclosure has been approved or retained.

Secondary or inconsistent disclosure

A notice exists, but timing, placement, wording or accessibility is incomplete.

Clear disclosure record

Wording, placement, first-exposure timing, accessibility, approval and publication proof are retained.

5. Internal review confirmation

I confirm that these selections are ready for internal legal, compliance, privacy, product or procurement review.

Disclaimer: This tool separates provider, deployer and evidence-dependency questions under Article 50. Final classification and implementation decisions require review of the applicable facts, official sources and qualified advice.

Article 50 Transparency Evidence Validator FAQ

What does Article 50 Transparency Evidence Validator help me check?

Article 50 Transparency Evidence Validator creates a role-aware internal evidence record without producing a compliance score. 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, assumptions used, and any decisions that require legal, privacy, procurement, or security follow-up.

Article 50 evidence fields to add after the Code update

Article 50 scenario: direct AI interaction, synthetic content, emotion recognition, biometric categorisation, deepfake, or public-interest AI-generated/manipulated text.
Code measure considered and whether the organisation plans to sign or follow a Code-aligned route.
Provider marking dependency and provider evidence requested.
EU icon considered or used, with a note that icon use alone is not legal proof.
Human-facing label text, label placement, first-interaction or first-exposure timing, and accessibility check.
Public-interest text review outcome, human review or editorial responsibility, exception rationale, approval owner, date, and screenshot or record location.

Article 50 Code update FAQ

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. The practical change for deployers 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.
