The Digital Omnibus on AI (Regulation (EU) 2026/1744) entered into force on 27 July 2026. It postponed certain high-risk system obligations while leaving Article 50 transparency requirements and Chapter V duties for general-purpose AI models in place.
EU AI Act Amendments Preserve Article 50 Transparency Duties
Article 50 obligations apply from 2 August 2026. Providers of generative systems already on the market before that date must meet machine-readable marking rules by 2 December 2026. These rules require outputs to carry detectable markers showing synthetic audio, image, video or text content.
Interactive AI systems must inform users when they interact with AI unless the context makes it obvious. Deployers face separate duties for deepfakes and certain public-interest text outputs. Exceptions cover law enforcement uses and assistive editing tools.
GPAI model obligations under Articles 53 and 55 have applied since 2 August 2025. Providers must supply documentation to downstream users, maintain copyright policies and publish summaries of training data. The Omnibus introduced no alterations to these core duties.
Digital Omnibus Adjustments and Compliance Timeline
The Omnibus shifted high-risk deadlines in Annex III to 2 December 2027 and Annex I to 2 August 2028. Transparency and GPAI rules remained on their original schedule. The European AI Office has started sending information requests to GPAI providers covering transparency, copyright, safety and security.
Voluntary codes of practice endorsed by the Commission and AI Board cover both output transparency and model-level documentation. Guidelines published in July 2026 offer practical examples. Further technical standards and training-summary templates remain under development.
Enforcement begins on 2 August 2026 through the AI Office and national authorities. Non-compliance with GPAI rules can trigger fines. Companies should map existing systems against Article 50 marking and disclosure needs, review training-data summaries and test interoperable detection solutions ahead of the December 2026 deadline for legacy models.
Frequently asked questions
What changed for general-purpose AI transparency under the 2026 Omnibus?
The Omnibus postponed some high-risk deadlines but kept Article 50 transparency rules and Chapter V GPAI obligations unchanged in substance and timing.
When must providers mark synthetic content under Article 50?
Marking requirements apply from 2 August 2026. Legacy systems on the market before that date have until 2 December 2026 to implement machine-readable markers.
Do GPAI model documentation duties still apply?
Yes. Articles 53 and 55 obligations on documentation, copyright policies and training data summaries have been in force since 2 August 2025.
Where can companies find practical guidance on compliance?
The Commission published guidelines in July 2026. Voluntary codes of practice and upcoming technical standards provide additional templates and examples.
