On 10 June 2025, the European Parliament published an “At a Glance” factsheet detailing the implementation timeline of the EU Artificial Intelligence Act (AI Act), the world’s first comprehensive AI regulatory framework. The document sets out the Act’s history, purpose, core provisions and, above all, the staggered schedule by which its requirements will enter into force across the European Union.
Background and Purpose
The AI Act was formally adopted by the European Parliament on 13 March 2024 and published in the Official Journal on 12 July 2024, entering into force twenty days later (1 August 2024). It establishes a risk-based regulatory regime for AI systems, dividing them into “unacceptable,” “high,” “limited” and “minimal” risk categories. Its overarching goal is to ensure that AI deployed in the EU is safe, transparent and respectful of fundamental rights, while fostering innovation across the single market.
What the Factsheet Includes
The factsheet serves as a concise guide to:
- History & Purpose: tracing the AI Act from proposal (April 2021) through political agreement (December 2023) to adoption and entry into force.
- Key Provisions: outlining definitions (Chapter I), prohibited practices (Chapter II), high-risk system rules (Chapter III), general-purpose AI obligations (Chapter V) and enforcement mechanisms (Chapter IX).
- Staggered Implementation Steps: detailing when each set of rules becomes applicable, culminating in full effectiveness by 2027.
Timeline of Implementation
- 2 February 2025
- Chapters I (general provisions) and II (prohibited AI practices) enter into force.
- European Commission publishes non-binding guidelines on prohibited practices, clarifying, for instance, bans on social scoring, predictive policing and real-time biometric identification in public spaces.
- 2 May 2025
- Completion of the Code of Practice for General-Purpose AI (GPAI) models—covering large language models and other foundation models—either by industry consensus or, failing that, EU Commission intervention.
- 2 August 2025
- Entry into force of:
- Designation of notified bodies and authorities for high-risk AI systems;
- Obligations for GPAI model providers (governance, transparency, technical documentation, incident reporting);
- Penalties regime (excluding fines specific to GPAI models);
- Confidentiality requirements in post-market monitoring.
- Entry into force of:
- 2 February 2026
- Commission issues guidelines on the classification rules for high-risk AI systems (Article 6), providing practical examples and clarifying Annex III criteria.
- 2 August 2026
- General application date for the remainder of the AI Act, including fines for GPAI model breaches and all high-risk system requirements in Annex III—except Article 6(1), which has a later deadline.
- By this date, national authorities must be fully empowered to enforce the Act across Member States.
- 2 August 2027
- Entry into force of Article 6(1) (classification rules for high-risk AI systems embedded into regulated products) and Annex I obligations, marking the completion of the Act’s phased rollout.

Significance and Next Steps
This staggered approach balances the need for rapid prohibition of the most dangerous uses of AI with practical lead times for industry, regulators and Member States to adapt. Over the next two years, stakeholders must:
- Audit and Classify all AI systems and GPAI models in use (2 February 2025)
- Develop Compliance Frameworks: risk management, documentation, human-oversight mechanisms and AI literacy programs for personnel (2 February 2025)
- Engage with Guidelines: monitor Commission publications and standardization efforts (e.g., CEN-CENELEC harmonized standards due end-2025).
By 2 August 2027, the EU will have achieved a fully operational, risk-based AI regulatory regime, setting a global precedent for trustworthy AI governance.
