Understanding the EU AI Act: A Risk-Based Approach to Regulation

Summary
The EU AI Act regulates AI systems by risk: some practices are banned, high-risk systems face strict requirements, certain systems must be transparent, and most applications face no new obligations. It entered into force in August 2024, with obligations applying in phases.
Key takeaways
- 01Rules scale with the level of risk
- 02Strict duties for high-risk systems
- 03Obligations phase in over several years

The European Union's Artificial Intelligence Act is the first comprehensive legal framework for AI from a major regulator. It entered into force in August 2024, with obligations applying in phases over the following years.
A risk-based framework
- Unacceptable risk: practices considered a clear threat to safety or rights are prohibited.
- High risk: systems used in sensitive areas — such as critical infrastructure, education, employment and essential services — must meet strict requirements including risk management, data quality, documentation, human oversight and accuracy.
- Transparency obligations: people must be told when they interact with certain AI systems, such as chatbots, and some AI-generated content must be identifiable.
- Minimal risk: most AI applications face no new obligations.
General-purpose AI models
The Act also sets obligations for providers of general-purpose AI models, with additional requirements for the most capable models that may pose systemic risks.
What organizations should do
- Inventory the AI systems you build or use and identify their risk category.
- Put documentation, human oversight and transparency practices in place early.
- Follow official guidance from the European Commission as implementation progresses.
