Article 50 Transparency Obligations Under the EU AI Act

When Article 50 transparency obligations apply, who must inform users, and what changed after the Omnibus.

Legal status caveat. The Digital Omnibus on AI reached political agreement on May 7, 2026; the European Parliament formally endorsed it June 16, 2026 and the Council gave final approval June 29, 2026. The deferred dates take legal effect only upon publication in the Official Journal, with entry into force on the third day after publication, which is expected imminently / before Aug 2, 2026.

Article 50 transparency obligations apply

Users must be informed when interacting with an AI system; AI-generated or manipulated content, including deepfakes, must be disclosed; disclosure duties apply for emotion-recognition and biometric-categorization systems. Article 49 EU database registration framework and governance/enforcement provisions also apply. This date was not deferred.

Changed by Omnibus Original: August 2, 2026

Machine-readable marking grace period ends for older generative systems

The machine-readable marking/watermarking duty under Article 50(2) applies to generative systems placed on the market before Aug 2, 2026 after a four-month grace period. Systems placed on the market on or after Aug 2, 2026 must comply from placement.

Changed by the Digital Omnibus on AI, pending Official Journal publication for legal effect.

When does Article 50 apply?

The main Article 50 transparency milestone is rendered above from the deadline data. It covers direct AI interaction notices, AI-generated or manipulated content disclosures, deepfake disclosures, and disclosures for emotion-recognition and biometric-categorization systems.

Was this deadline delayed?

No. The Omnibus changed the machine-readable marking grace period for some older generative systems, but the main transparency date was not deferred.

Do the transparency rules apply to deployers?

Some duties are provider-facing and some are deployer-facing. A deployer using AI to interact with people, disclose deepfakes, or run emotion-recognition or biometric-categorization systems should treat this page as a scoping prompt, not final legal advice.
