The EU AI Act, explained for AI teams

The EU AI Act is the world's first comprehensive AI law, and it is now in force on a staggered timeline. If you build or deploy AI in the European market, it applies to you - regardless of where your company is based. Here is the practical version.

A risk-based law, not a model ban

The Act does not regulate 'AI' as one thing. It sorts systems into risk tiers and attaches obligations to each. Most products fall into the lighter tiers; a minority face strict requirements.

The four risk tiers

• Unacceptable risk: banned outright (e.g. social scoring, certain biometric surveillance).
• High risk: heavy obligations (e.g. AI in hiring, credit, medical devices, critical infrastructure).
• Limited risk: transparency duties (e.g. tell users they are talking to AI, label AI-generated content).
• Minimal risk: most applications, few specific obligations.

What high-risk actually requires

If your system is high-risk, expect requirements around risk management, data governance, documentation, human oversight, accuracy, and logging. The common thread is that you must be able to show how the system works and how it is controlled.

Why infrastructure is part of compliance

Several obligations - data governance, logging, security, traceability - are far easier to meet when you control the stack. If your data and inference run on infrastructure you govern, inside the EU, you can answer auditors directly instead of chasing a hyperscaler's attestations.

Compliance is easiest when you can answer the auditor yourself, not forward the question to a vendor.

Practical steps to take now

• Classify each AI feature by risk tier.
• Map where your data and inference physically run, and under whose jurisdiction.
• Keep documentation and logs from day one, not retroactively.
• Prefer infrastructure that keeps data in-EU and gives you access to the logs.

The Act rewards teams that designed for governance early. Sovereign, EU-based infrastructure does not make you compliant on its own - but it removes a whole category of hard questions. (This is an overview, not legal advice; confirm specifics with your legal team.)
