The EU AI Act explained, what companies must do now.

The EU AI Act is the world's first comprehensive AI regulation. To many companies it first looks confusing. This page explains in plain language what the EU AI Act governs, which risk classes exist, what Art. 4 on AI literacy has required since 02.02.2025 and how it relates to GDPR. It is the explainer pillar. The concrete consulting offer is on EU AI Act consulting that makes your AI practically prepared.

What the EU AI Act is

The EU AI Act, officially the European Union's AI regulation, came into force in 2024 and applies in stages over several years. It does not regulate AI across the board but by the risk of each application. The goal is to enable innovation while protecting fundamental rights and safety. It applies to providers and deployers of AI systems who use or offer them in the EU, regardless of where the company is based.

The four risk classes

The EU AI Act divides AI systems into four levels. Prohibited practices, such as social scoring by public authorities or manipulative systems, are banned. High-risk systems, for example in critical infrastructure, human resources or credit scoring, face strict duties like risk management, documentation and human oversight. Systems with limited risk, such as chatbots, face transparency duties, users must know they are interacting with AI. Systems with minimal risk, the large majority, are largely free. The first practical step for every company is to assign its own applications to these classes.

Art. 4, the AI literacy obligation since 02.02.2025

Since 02.02.2025, Art. 4 applies. It requires companies to ensure a sufficient level of AI literacy among everyone who operates or uses AI systems on their behalf. It is important what this is not. It is not an obligation to a specific certificate and not a formal exam. What is required is competence appropriate to role, task and context, and demonstrable in case of doubt. In practice this means leadership, business units and the people at the systems each need suitable knowledge, and the company should be able to evidence how it builds it.

What companies must concretely do now

The pragmatic path consists of a few steps. First, an inventory of all deployed and planned AI systems. Second, assign each system to a risk class and derive the resulting duties. Third, plan the literacy build-up under Art. 4, clarifying who needs which knowledge and how it is taught. Fourth, ensure documentation and transparency, especially for systems with user contact. Fifth, add the GDPR view, because both frameworks interlock. These steps can be integrated into an AI roadmap instead of running them as a separate project.

EU AI Act and GDPR

The EU AI Act and GDPR govern different things but overlap. GDPR protects personal data and regulates its processing. The EU AI Act governs AI systems by risk. In practice both meet at many points, such as transparency toward data subjects, documentation and automated decisions. Anyone introducing AI should consider both together so no requirement slips through. Where data is sensitive, it helps to keep processing in Germany and the EU.

Why compliance can be an advantage

Many see regulation only as a burden. With the EU AI Act the other view pays off. If you clarify early which applications are allowed and how competence is built, you do not have to slow AI projects out of uncertainty. Compliance turns into a head start because you build on a cleared frame rather than assumptions. And toward customers and partners, demonstrable AI literacy is increasingly a trust signal.

FAQ

When does the EU AI Act apply?
It came into force in 2024 and applies in stages over several years. Individual parts take effect at different times. The AI literacy obligation from Art. 4 applies since 02.02.2025. Further duties for high-risk systems follow the timeline set in the law.
Does the EU AI Act apply to small companies too?
Yes. The EU AI Act makes no general exception for small companies. The concrete duties depend heavily on the risk of the application. A small company with a simple chatbot mainly has transparency duties, not extensive risk management like high-risk systems.
What is a sufficient level of AI literacy?
The law names no fixed number of hours and no certificate but competence appropriate to role and context. Someone who only operates AI needs different knowledge than someone who introduces or is responsible for it. What matters is that the company can traceably evidence how it ensures this.
What happens in case of violations?
The EU AI Act provides tiered fines based on severity and turnover. Prohibited practices carry the sharpest sanctions. For most companies the practical driver is not the penalty, though, but the ability to use AI safely and without friction.
Where is the best place to start?
With an inventory of the deployed and planned AI systems and their assignment to the risk classes. From that follows which duties really apply. This step and the Art. 4 literacy build-up are handled by the EU AI Act consulting on EU AI Act consulting that makes your AI practically prepared.
