EU AI Act enforcement enters a new phase — and Article 50 is live
From 2 August 2026, the Commission's AI Office and national authorities began enforcing applicable AI Act rules, while Article 50 transparency obligations started applying.

What is enforceable now?
The enforcement position depends on which provision has entered into application. The Commission highlights prohibited-practice rules, Article 50 transparency obligations and GPAI rules among the applicable layers, while the main high-risk regime follows the later 2027/2028 timetable.
Article 50 is the immediate operational priority
Interactive AI systems may need to inform people they are interacting with AI. Providers of generative systems can face marking/detection duties. Deployers can face labelling/disclosure duties for deepfakes and specified public-interest text.
Who enforces Article 50?
The Commission explains that national competent market-surveillance authorities will generally enforce Article 50, with the AI Office holding specified competence in particular AI-system/GPAI-platform circumstances.
What companies should verify now
- Inventory interactive and generative AI features.
- Identify which Article 50 paragraph and actor role applies.
- Test disclosure placement and content.
- Map marking/provenance capabilities and technical limitations.
- Define deepfake/public-interest publication workflows.
- Preserve implementation evidence and review records.
