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.

    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

    The transition window for systems placed on the market before the transparency rules applied closes: synthetic content they output must carry machine-readable marking.

    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

    High-risk system obligations fully apply

    The full high-risk regime (Annex III systems, conformity assessments) applies, completing the Act's staggered rollout.

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