The EU AI Act is the European Union's comprehensive law regulating artificial intelligence, the first of its kind. It takes a risk-based approach: it…
Understand the EU AI Act as a risk-based, first-of-its-kind AI law.
The EU AI Act is the European Union's comprehensive regulation of AI — the first broad AI law globally, and influential well beyond Europe. Its core idea is to regulate by risk: the higher the potential harm of an AI use, the stricter the rules, rather than treating all AI the same.
This produces a tiered system. A small number of uses are banned outright, a defined set of high-risk uses face heavy obligations, some uses need only transparency, and the rest are largely unregulated. The category depends on how the system is used, not the technology alone.
Learn the tiers and what each demands.
Unacceptable-risk uses are prohibited — for example, government social scoring and certain manipulative or exploitative systems. These are simply not allowed in the EU.
High-risk uses — AI in areas like hiring, credit scoring, education, critical infrastructure, and medical devices — are permitted but carry the heaviest obligations: risk management, data governance, documentation, human oversight, accuracy and robustness, and registration. Most of the Act's compliance work concerns this tier.
Limited-risk uses require transparency. If users interact with a chatbot, they must be told they are dealing with AI; AI-generated or manipulated content (like deepfakes) must be disclosed. The duty is to inform, not to overhaul the system.
Minimal-risk uses — the large majority, such as spam filters or AI in games — face no new obligations under the Act. Most everyday AI falls here.
See the separate rules for broadly capable models.
Beyond specific uses, the Act adds obligations for general-purpose AI (GPAI) models — the broadly capable foundation models, including large language models. Providers must supply technical documentation, publish a summary of training-data sources, and put a policy in place to respect EU copyright law.
The most capable models, judged to carry systemic risk, face extra duties such as model evaluation, adversarial testing, incident reporting, and cybersecurity measures. This is how the Act reaches the base models that power many downstream applications.
Know the Act's reach and timeline, and how to prepare.
The Act applies not only to EU companies but to any provider or deployer whose AI output is used in the EU, so non-EU firms are often in scope — similar to how GDPR reached far beyond Europe. Obligations phase in over time: the banned practices apply first, then GPAI rules, with high-risk obligations following later, rolling out across 2025 to 2027.
To prepare, inventory your AI uses, classify each by risk tier, and focus compliance effort on anything high-risk while meeting transparency duties for user-facing AI. Non-compliance carries significant fines, so early classification pays off.
This is an orientation, not legal advice, and details evolve as guidance is issued. For real deployments in scope, classify carefully and consult qualified counsel — especially for anything that might be high-risk.
The EU AI Act is the first comprehensive AI law, regulating by risk. Unacceptable uses are banned; high-risk uses (hiring, credit, medical) carry heavy obligations like risk management, documentation, and human oversight; limited-risk uses need transparency (tell users it's AI); minimal-risk uses are free. General-purpose AI models have their own documentation and copyright duties, with extra requirements for systemic-risk models. It reaches anyone serving the EU market, phasing in over 2025-2027 — so inventory and classify your AI early.
Take an AI feature you might build — say a resume-screening tool for EU applicants. Decide its likely risk tier, name two obligations that would apply, and explain why a chatbot version would fall into a different, lighter tier.
What is the core approach of the EU AI Act?
The Act tiers obligations by potential harm, so requirements depend on how an AI system is used, not the technology alone.
What is required of high-risk AI systems?
High-risk uses (hiring, credit, medical, etc.) are permitted but carry the Act's most substantial compliance requirements.
What obligations does the Act place on general-purpose AI models?
GPAI providers have transparency and documentation duties, and the most capable models face additional systemic-risk obligations.
Who does the EU AI Act apply to?
Like GDPR, the Act has extraterritorial reach, so non-EU firms serving the EU market are often in scope, with rules rolling out over several years.
