# EU AI Act enters into force

The EU Artificial Intelligence Act (Regulation (EU) 2024/1689), the world's first comprehensive AI law, entered into force on 1 August 2024 with obligations phased in over 2025–2027 under a risk-based approach.

## Key facts
- Regulation (EU) 2024/1689; European Parliament approved it on 13 March 2024
- Published in the Official Journal on 12 July 2024; in force 1 August 2024
- Prohibited practices apply from 2 February 2025
- General-purpose AI model obligations apply from 2 August 2025 (GPAI Code of Practice published July 2025)
- Most high-risk obligations scheduled from 2 August 2026

## What happened

After three years of negotiation, the EU's AI Act became law, classifying AI systems by risk and imposing duties on providers of general-purpose AI models.

## Why it matters

The first binding horizontal AI regulation by a major jurisdiction, with extraterritorial effect on all labs serving the EU market.
