Detailed Timeline

✓ In Effect Foundation

1 August 2024

EU AI Act Enters into Force

The regulation was published in the Official Journal and entered into force. The 24-month countdown to full application began. At this point, no obligations were directly enforceable yet — this date simply started the clock.

Article 113

✓ In Effect Phase 1

2 February 2025

Prohibited Practices + AI Literacy Apply

All eight prohibited AI practices under Article 5 became enforceable — social scoring, subliminal manipulation, untargeted facial scraping, emotion recognition in workplaces and schools, biometric categorisation on sensitive attributes, and more. AI literacy obligations (Article 4) also kicked in: providers and deployers must ensure staff have sufficient understanding of the AI systems they work with.

Articles 4, 5 · Chapters I, II

✓ In Effect GPAI

2 May 2025

GPAI Codes of Practice Due

Codes of practice for General-Purpose AI model providers were supposed to be finalised by this date, giving providers a framework to demonstrate compliance ahead of the August 2025 enforcement. These codes cover transparency, copyright compliance, and training data documentation.

Chapter V

✓ In Effect Phase 2

2 August 2025

GPAI Rules + Governance Operational

Rules for General-Purpose AI models became fully applicable. All GPAI providers must now maintain technical documentation, provide downstream provider information, comply with copyright rules, and publish training data summaries. GPAI models with systemic risk (>10^25 FLOPs) face additional obligations: adversarial testing, incident reporting, cybersecurity measures, and energy consumption reporting. Governance structures, notified body frameworks, and penalty provisions also took effect.

Chapters III§4, V, VII, XII · Article 78

Upcoming — Critical Phase 3

2 August 2026

Majority of Rules Apply — Full Enforcement Starts

This is the deadline that matters most under current law. All high-risk AI systems listed in Annex III must comply with the full set of requirements under Articles 8–15: risk management, data governance, technical documentation, record-keeping, transparency, human oversight, accuracy, robustness, and cybersecurity. Market surveillance authorities begin active enforcement. Deployer obligations (Article 26) are fully enforceable, including fundamental rights impact assessments (Article 27). Transparency obligations under Article 50 (chatbots, deepfakes, emotion recognition disclosure) also kick in. Article 99 sets maximum fine tiers for these obligations, while actual penalty application depends on the breach, national rules, and supervisory practice.

Upcoming Phase 4

2 August 2027

High-Risk AI in Regulated Products

The final transition period ends. High-risk AI systems used as safety components of products covered by existing EU harmonised legislation — medical devices, machinery, vehicles, toys, lifts, marine equipment — must now comply with the AI Act on top of their existing product safety regulations. This affects AI embedded in physical products under Annex I, Section B.

Article 6(1) · Annex I

Digital Omnibus Watch

The European Commission's Digital Omnibus proposal (November 2025) could conditionally push back certain high-risk AI system deadlines from August 2026 to proposal-stage dates such as 2 December 2027 and 2 August 2028 — but only if the law is amended. As of 20 April 2026, the Council adopted its position on 13 March 2026, Parliament adopted its position on 26 March 2026, and trilogue negotiations have launched. It is not enacted law.

Our recommendation: Plan for 2 August 2026 as the binding high-risk compliance deadline. If an Omnibus backstop is later adopted, treat it as contingency time for refinement — not as your baseline. Evidence assembly, risk management system setup, and training programmes still take months, not weeks.
