Why a European Law Reaches You
The EU has about 450 million consumers, and its laws travel. GDPR (the 2018 privacy law) became the de facto global standard because companies do not build two versions of their data stack. The same pattern, called the Brussels Effect, is happening now for AI.
Four risk tiers
- 1Unacceptable risk: banned outright. Social scoring by governments, manipulative subliminal systems, untargeted facial scraping, most real-time public face recognition, emotion recognition at work and school.
- 2High risk: heavily regulated. AI in hiring, credit, education, law enforcement, migration, medical devices, critical infrastructure. Risk management, logging, human oversight required.
- 3Limited risk: transparency only. Chatbots must say they are AI. Deepfakes must be labeled.
- 4Minimal risk: no obligations. Spam filters, recommender tweaks, most consumer AI falls here.
General-purpose AI (GPAI) track
A separate track covers foundation models. Effective August 2025, GPAI providers must publish technical documentation, respect copyright opt-outs, and summarize training content. Models above 10^25 FLOPs of training compute are presumed to pose systemic risk and face additional evaluation and incident-reporting obligations.
Timeline
- February 2025: prohibitions live (the banned uses)
- August 2025: GPAI obligations active, AI Office operational
- August 2026: high-risk and transparency rules enforce, fines kick in (up to 7% of global revenue)
- August 2027: high-risk AI embedded in regulated products (medical, vehicles, toys)
Compare the options
| Dimension | EU | US | China |
|---|---|---|---|
| Shape | Comprehensive, risk-tiered | Sectoral + state laws | Sectoral + national review |
| Foundation models | Covered (GPAI) | Voluntary commitments | Licensed, security review |
| High-risk lists | Enumerated in law | NIST voluntary framework | Algorithm registry |
| Max penalty | 7% global revenue | Varies by agency | License suspension |
“The AI Act is not a final answer. It is the first serious attempt to write rules for systems that did not exist when we started writing.”
Key terms in this lesson
The big idea: whatever you think of the Act, the odds are you will use products built to its standards. Reading the tiers is the cheapest way to understand AI regulation anywhere.
