EU Code for AI-generated content transparency
EU AI Office issues voluntary Code to support Article 50 labelling duties; signatories listed in July; transparency rules apply from 2 Aug 2026.

What happened
The European Union’s AI Office has published a voluntary Code of Practice aimed at supporting the Article 50 transparency obligations of the EU AI Act on AI‑generated content. The Code is presented as implementation guidance that sits alongside the statutory Article 50 duties (marking and labelling of AI‑generated content). The AI Office says it will publish a list of organisations that sign up to the voluntary Code in July; the Article 50 transparency duties themselves become applicable from 2 August 2026 across the EU.
The resources and explanatory materials are available via the EU AI Act Service Desk and accompany the broader standardisation work the Commission is driving to produce technical and conformity tools for the AI Act. The standardisation effort is intended to feed into consistent technical specifications and voluntary mechanisms that operationalise the law’s requirements.
Why this matters for HR
The Article 50 transparency duties and the newly published Code are directly relevant to HR teams because they affect any workplace use of generative AI that produces content communicated to people inside or outside the organisation.
Specific HR touchpoints include:
- Recruitment and candidate communications: automated cover‑letter generation, AI‑assisted outreach messages or interview summaries that are redistributed to candidates must be considered under the labelling duty.
- Internal communications and learning: AI‑generated training modules, staff newsletters, or policy drafts produced or substantially edited by generative models may need clear disclosure that AI contributed to the content.
- Onboarding and documentation: HR materials created with generative AI — from role descriptions to assessment reports — could trigger marking requirements when shared with employees or external stakeholders.
- Vendor and tool procurement: HR’s supplier contracts and data‑processing agreements will need to align with the transparency regime and any voluntary commitments vendors make under the Code.
For HR leaders the immediate takeaway is operational: identify where generative models are used, determine the “point of disclosure” for affected content, and plan how to label content so it meets the transparency standard that Article 50 requires. Because the Code is voluntary, signing it may offer a practical route to demonstrate good practice ahead of the 2 August 2026 effective date.
Compliance and legal context
The transparency duties stem from Article 50 of the EU AI Act; the Code is explicitly framed as voluntary guidance to support compliance with those statutory duties. The EU’s standardisation work — which the Commission is coordinating — aims to produce technical specifications and common approaches that organisations can use to align with the AI Act’s requirements. HR and compliance teams should therefore track both the Code and the parallel standardisation outputs, since the technical standards will shape what “meaningful disclosure” looks like in practice.
The resources page published by the EU AI Office is intended to help organisations translate the legal text into operational processes. HR teams that manage vendor relationships, communications and employee data flows should involve legal and privacy colleagues to ensure labelling practices do not collide with other obligations (for example, privacy notices, employment contracts or national labour rules where applicable).
What to watch next
- Signatory list in July: the AI Office will publish organisations that have signed up to the voluntary Code. HR and procurement should monitor that list to see which vendors and peers have committed to the guidance.
- Standardisation outputs: technical specifications under the AI Act’s standardisation roadmap will further define how to implement labelling and what metadata or technical indicators are expected.
- Implementation guidance from the AI Office: additional practical materials or templates for disclosure could be issued between now and the 2 August 2026 deadline.
- Vendor commitments and contracts: expect suppliers to update terms and to offer tooling that supports automatic labelling. HR should map contract clauses and SLAs to the transparency duties.
Practical steps for HR now are straightforward: inventory generative‑AI use cases, define who is accountable for labelling decisions, and engage legal, communications and procurement colleagues to build disclosure workflows that will scale once Article 50 becomes applicable.
