Chapters I and II will apply from this date (Article 113(a)). These include the general provisions (e.g., geographic scope, definitions) and the provisions on prohibited AI practices (see our client alert).

From this date, Chapter III, Section 4 (Notifying authorities and notified bodies), Chapter V (General-purpose AI models), Chapter VII (Governance) and Chapter XII (Penalties) will apply (except for Article 101, which deals with fines for providers of general-purpose AI models).

• Chapter III, Section 4 deals with notifying authorities and notified bodies, which are essential for the establishment of conformity assessment bodies.
• Chapter V contains the provisions related to general-purpose AI models introduced late in the legislative process; for example, the mandatory notification procedure for the provider (Article 52 (1)), documentation requirements (Article 53) and the appointment of an authorized representative (Article 54). Article 55 contains additional responsibilities focusing on the evaluation and mitigation of systemic risk and cyber and infrastructure security.
• Chapter VII sets out the governance structure on the EU level, including the AI Office, the European Artificial Intelligence Board, the advisory forum and the scientific panel. On the Member State level, the competent authorities must be appointed by this date (Article 70(2)).

• Chapter XII deals with penalties. This includes Article 99(3), which specifies the fines for noncompliance with prohibited AI practices referred to in Article 5. These fines can reach €35 million, or up to 7% of worldwide annual revenue, if the offender is an undertaking.

The obligations regarding high-risk AI systems will apply from this date, including risk and quality management systems, diligent data governance, technical documentation, recordkeeping, and transparency and information obligations.

Chapter IV addresses operators of AI systems directly interacting with humans, generative AI systems, and emotion recognition or biometric categorization systems, introducing disclosure and information responsibilities (see our client alert).

By this date, Member States must have implemented rules on penalties and other enforcement measures and notified the European Commission about them (Article 99).

At least one AI regulatory sandbox must be operational at a national level (Article 57(1)).
