The EU AI Act applies to organisations that develop, provide or use AI systems in a professional context in the EU. Obligations vary by role and use case. Article 50 transparency rules have applied since 2 August 2026. Depending on the organisation's role and the system in use, they include informing people when they are interacting directly with AI, machine-readable marking of certain synthetic outputs, and visible labelling of deepfakes and certain AI-generated text published to inform the public without human review or editorial control. Prohibited AI practices and AI literacy requirements have applied since February 2025. The AI Omnibus has set later application dates for high-risk system rules: 2 December 2027 for stand-alone systems in Annex III, and 2 August 2028 for high-risk AI embedded in regulated products under Annex I. Other AI Act obligations remain subject to their own application dates.
