Providers must disclose AI interaction (50(1)) and mark synthetic audio/image/video/text as machine-readable (50(2)). Deployers must notify people exposed to emotion-recognition or biometric-categorisation systems (50(3)) and label deepfakes and AI-generated text published to inform the public on matters of public interest (50(4)).
Who must comply
Providers and deployers of AI systems placing outputs on the EU market.

Status and notes
Binding from 2 August 2026 (firm, per Regulation (EU) 2024/1689). A short transitional period for the 50(2) machine-readable marking of pre-existing generative-AI systems was set by the AI/Digital Omnibus amending regulation (final text adopted 29 June 2026); it is reported as 2 December 2026 by the European Parliament's Legislative Train, but is not yet published in the Official Journal and the original Commission proposal said 2 February 2027 — treat the exact transitional date as provisional until OJ publication. A voluntary Code of Practice on Transparency of AI-Generated Content was published by the EU AI Office on 10 June 2026.
