On August 2, 2026, the transparency obligations under Article 50 of the EU Artificial Intelligence Act became enforceable. Article 50 imposes four distinct duties. Providers must design AI systems that interact directly with people, such as chatbots and voice assistants, to inform users that they are dealing with an AI system, unless that fact is obvious from the circumstances. Providers of generative AI systems must embed machine-readable markings in synthetic audio, image, video, and text output so that the content is detectable as artificially generated. Deployers of emotion-recognition or biometric-categorization systems must inform the individuals exposed to them. Finally, deployers must disclose deepfakes and AI-generated text published on matters of public interest, unless the content has undergone human editorial review with a person assuming responsibility for its publication. Violations can result in administrative fines of up to 15 million euros or 3% of worldwide annual turnover, whichever is higher.

 

These obligations took effect on schedule even as other parts of the Act were delayed. The "Digital Omnibus on AI" (Regulation (EU) 2026/1744), which entered into force on July 27, 2026, postponed the Act's high-risk system requirements to December 2027 but left the Article 50 compliance date in place. The only relief granted was a grace period, running until December 2, 2026, for generative AI systems already on the market before August 2, 2026, to implement the machine-readable marking requirements; content generated before that date does not need to be labeled retroactively. To support implementation, the European Commission adopted non-binding interpretive guidelines on Article 50 on July 20, 2026, and on July 31, 2026, the EU AI Office published a voluntary Code of Practice on Transparency of AI-Generated Content.

 

Article 50 applies to any AI system placed on the EU market as well as to providers and deployers located outside the EU where the system's output is used within the Union. A U.S. company whose customer-facing chatbot or content-generation tool reaches EU users is therefore subject to these rules today, even without a European entity or infrastructure. Businesses should inventory their EU-facing AI products, confirm that conversational interfaces identify themselves as AI, and verify that generative outputs carry compliant markings before the December 2 deadline.
