EU AI Act Article 50 Transparency Obligations Enter Into Application

EU AI Act Article 50 Transparency Obligations Enter Into Application

On August 2, 2026, the far-reaching transparency requirements under Article 50 of the EU AI Act (Regulation (EU) 2024/1689) officially entered into application. This marks a critical compliance milestone for both European and international businesses. Any company whose AI systems interact with EU users or whose AI-generated content reaches audiences in the European Union must comply, regardless of physical presence in Europe. Non-compliance carries severe penalties of up to €15 million or 3% of total worldwide annual turnover, whichever is higher.

While the "Digital Omnibus on AI" agreed to in May 2026 postponed high-risk AI system deadlines to 2027 and 2028 (see EU AI Act Omnibus Agreement Postpones High-Risk Deadlines to 2027 and 2028), it did not delay the Article 50 transparency obligations. However, a limited transitional window was provided for the machine-readable marking requirements under Article 50(2).

Core Obligations Under Article 50:

1. AI Interaction Disclosure (Article 50(1)): Providers must design interactive AI systems (such as chatbots and customer-service AI agents) so that human users are clearly informed they are interacting with an AI system, unless this is obvious from the context.
2. Generative AI Marking and Detection (Article 50(2)): Providers of generative AI systems must ensure that their outputs (audio, image, video, or text) are marked in a machine-readable format and detectable as artificially generated or manipulated. Under the May 2026 Omnibus agreement, generative AI systems already on the market before August 2, 2026, have a transitional period until December 2, 2026, to meet this machine-readable marking requirement.
3. Biometric and Emotion Recognition Disclosure (Article 50(3)): Deployers of emotion recognition or biometric categorization systems must inform individuals exposed to them.
4. Deep Fake Labeling (Article 50(4)): Deployers of AI systems that generate or manipulate "deep fakes" (synthetic audio, image, or video depicting real people, places, or events as authentic) must clearly and conspicuously disclose that the content has been artificially generated or manipulated.¹
5. Public Interest Text Disclosure (Article 50(5)): Deployers of AI systems that generate or manipulate text published with the intent to inform the public on matters of public interest must disclose that the text has been artificially generated or manipulated.
