  "domain": "AI Governance & Law",
  "version": "1.0.0",
  "last_updated": "2026-04-28",
  "bluf": "EU AI Act (Regulation 2024/1689) Article 50 establishes transparency obligations for specific categories of AI systems that interact with natural persons or generate content, applicable from 2 August 2026 (24 months after entry into force per Article 113); Article 50 transparency obligations apply to four categories: (1) Article 50(1) - providers of AI systems intended to interact directly with natural persons must design and develop the system so that natural persons are informed they are interacting with an AI system - this covers chatbots, virtual assistants, and AI customer service systems; an exception applies where the AI nature of the system is obvious from the context; (2) Article 50(2) - deployers of AI systems that interact with natural persons must inform those persons that they are interacting with an AI system, unless the AI nature is obvious from the context or has been disclosed by the provider through Article 50(1) design; (3) Article 50(3) - providers of AI systems that generate synthetic audio, video, image, or text content must ensure outputs are marked with a machine-readable format identifying the content as AI-generated (watermarking or equivalent technical solution); Article 50(4) - deployers of AI systems generating synthetic content must disclose to natural persons when the content they are exposed to has been AI-generated or manipulated, for: deep fakes (video or image bearing resemblance to existing persons, places, or events); audio deep fakes; AI-generated images, video, or audio published in the public interest; a limited exception applies under Article 50(4) for legally authorised journalism purposes; the Article 50 transparency obligations apply to all AI systems meeting the specified criteria regardless of whether they are high-risk AI systems - they represent a baseline transparency floor below the full Article 26 deployer obligation framework; compliance with Article 50(3) watermarking requires technical solutions that are interoperable, effective, and difficult to remove.",
