EU AI Act deadline tracker

The AI Act applies in stages. These are the dates that matter for transparency compliance, kept current as Commission guidance evolves.

until the marking grace period ends (Dec 2, 2026)
  1. In force

    EU AI Act enters into force

    Regulation (EU) 2024/1689 formally enters into force, starting the staggered application clock for all obligations.

    Who this affects: Everyone building or deploying AI touching the EU market.

  2. In force

    Prohibited practices apply

    Bans on unacceptable-risk AI (social scoring, certain biometric practices) plus AI-literacy duties become applicable.

    Who this affects: Providers and deployers of the banned categories.

  3. In force

    GPAI model obligations apply

    Transparency and documentation duties for general-purpose AI model providers become applicable, alongside governance provisions.

    Who this affects: Foundation-model and GPAI providers.

  4. In force

    Article 50 transparency obligations enforceable

    Chatbot disclosure, machine-readable marking of synthetic content, and deepfake labeling duties are now enforceable, with penalties up to €15M or 3% of worldwide turnover. Regulation (EU) 2026/1744 (Digital Omnibus on AI) did not postpone this date.

    Who this affects: Anyone whose AI system interacts with people or generates content reaching EU users — including non-EU companies.

  5. Next deadline

    Marking grace period ends for pre-existing systems

    Providers of generative systems placed on the market before 2 August 2026 have until this date to meet Article 50(2) machine-readable marking. New systems had no extra runway. Content already in circulation before 2 August is not required to be marked retroactively.

    Who this affects: Providers of generative systems launched before August 2026 that have been relying on the grace period.

  6. Upcoming

    Watermark interoperability expectations

    Commission guidance anticipates interoperable, state-of-the-art marking and detection across providers — vendor lock-in stops being an excuse.

    Who this affects: Model providers and marking-tool vendors who must read each other's watermarks.

  7. Upcoming

    Annex III high-risk obligations apply

    Chapter III Sections 1–3 apply to AI systems classified as high-risk under Article 6(2) and Annex III. Regulation (EU) 2026/1744 moved this from the original 2 August 2026/2027 stagger to 2 December 2027.

    Who this affects: Providers and deployers of Annex III high-risk AI systems.

  8. Upcoming

    Annex I (product) high-risk obligations apply

    High-risk AI systems classified under Article 6(1) and Annex I (products and safety components covered by Union harmonisation legislation) apply from 2 August 2028 under Regulation (EU) 2026/1744.

    Who this affects: Providers of AI systems that are themselves products, or safety components of products, covered by Annex I legislation.
