The rule

Four transparency duties that are already law

Regulation (EU) 2024/1689 became applicable on 2 August 2026. Its Article 50 transparency duties apply from that date — no transition for these.

Art. 50(1)

AI interaction

Chatbots, assistants and voice systems must inform users they are interacting with AI — unless it is obvious from the context.

In force
Art. 50(2)

Synthetic media

AI-generated image, audio and video must be marked as artificially generated in a machine-readable format.

In force
Art. 50(3)

Deepfakes

Deepfakes must be labelled; where content serves the public interest, providers must disclose its artificial nature at first use.

In force
Art. 50(4)

Public-interest text

Deployers of AI text published to inform the public must disclose it — unless human-reviewed with editorial responsibility.

FAQ

What teams are asking right now

Is Article 50 in force?
Yes. The AI Act (Regulation (EU) 2024/1689) became applicable on 2 August 2026, and its Article 50 transparency duties apply from that date. Content generated before 2 August 2026 does not need to be labelled retroactively. [1][3]
What must a chatbot disclose?
Under Art. 50(1), AI systems intended to interact with people — chatbots, assistants, voice agents — must be designed and developed so users are informed they are interacting with an AI system, unless that is obvious from the circumstances and context of use. [2][5]
How must synthetic media be marked?
Under Art. 50(2), AI-generated image, audio or video content that constitutes a deepfake must be marked as artificially generated in a machine-readable format. Deepfakes are additionally labelled under Art. 50(3), with extra disclosure at first use where they serve the public interest. [2][4]
What about AI text published to inform the public?
Under Art. 50(4), deployers of AI systems that generate text published with the purpose of informing the public on matters of public interest must disclose that it is AI-generated — unless the text is subject to human review and a natural or legal person holds editorial responsibility. [2][3]
What are the fines?
Non-compliance with the transparency obligations can trigger fines of up to €15,000,000 or 3% of worldwide annual turnover, whichever is higher (Art. 99). [3][4]
