The world's most ambitious AI law passed in 2024. Here is what it actually does, when it kicks in, and why it matters if you do not live in Europe.

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

Unacceptable 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.
High risk: heavily regulated. AI in hiring, credit, education, law enforcement, migration, medical devices, critical infrastructure. Risk management, logging, human oversight required.
Limited risk: transparency only. Chatbots must say they are AI. Deepfakes must be labeled.
Minimal 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)

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.
— Dragoș Tudorache, EU Parliament co-rapporteur on the AI Act

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.
