Who this applies to
This obligation applies to providers of AI systems that interact with natural persons (e.g., chatbots) or generate synthetic content (e.g., deepfakes, AI-generated text/image/audio). It also covers deployers of such systems when they fall under high-risk classifications or general-purpose AI (GPAI) models with systemic risk. Scope is defined under Article 50(1) (transparency for AI systems) and Article 52(1)-(3) (obligations for GPAI providers).What is required
- Disclosure of AI interaction: Systems designed to interact with natural persons must inform users they are engaging with an AI, unless obvious from the circumstances (Article 50(1)).
- Synthetic content labeling: AI-generated or manipulated content (e.g., deepfakes, text, audio, video) must be clearly marked as artificially generated or manipulated, including via machine-readable metadata where technically feasible (Article 50(2)).
- GPAI transparency documentation: Providers of general-purpose AI models must publish detailed summaries of the content used for training, unless prohibited by copyright or trade secrecy (Article 52(1)).
- Systemic risk disclosures: Providers of GPAI models with systemic risk must additionally disclose:
Key deadlines
The primary deadline for this obligation is August 2, 2026 (Article 50 transparency, unchanged by the Digital Omnibus). The Article 50(2) machine-readable marking obligation moves to 2 December 2026 under the provisional agreement of 7 May 2026, pending formal adoption.Enforcement patterns
AI Act Article 50 transparency obligations take effect 2 August 2026. Annex III high-risk obligations are expected 2 December 2027, pending formal adoption of the Digital Omnibus (political agreement of 7 May 2026). No AI Act enforcement precedent currently exists. This page will be updated as enforcement cases emerge.Cross-border considerations
