Key Takeaways

- 2Prohibited AI practices have been banned since February 2025
- 3Fines reach up to €35M or 7% of global revenue for prohibited practices

- 5Compliance typically takes 12–18 months for high-risk systems — start early
The EU AI Act is now reaching full enforcement, and if your company uses AI, you need to understand these requirements.
The EU Artificial Intelligence Act (Regulation (EU) 2024/1689) entered into force on August 1, 2024. Prohibited AI practices have been banned since February 2, 2025. High-risk AI system requirements become mandatory on August 2, 2026 — the date many companies have been preparing for.
Who Is Affected
Any company deploying AI systems in the EU market, companies outside the EU if their AI affects EU citizens, AI providers, deployers, importers, and distributors. If you build, sell, or use AI tools that touch EU residents, this applies to you.
Risk Categories
Prohibited AI includes social scoring systems, real-time biometric identification in public spaces (with narrow exceptions), and manipulative AI that exploits vulnerabilities. These have been banned since February 2025.

High-risk AI includes recruitment tools, credit scoring, educational assessment, medical diagnosis, and law enforcement applications. Full requirements for these systems become mandatory August 2, 2026.
Limited risk requires transparency for chatbots and deepfakes — users must know they are interacting with AI.
Minimal risk includes spam filters and video games — no additional obligations.
Documentation Requirements
For high-risk systems: technical documentation covering design, data, and testing; risk assessment and mitigation measures; logging capabilities for traceability; instructions for use; human oversight measures; and performance monitoring procedures.
Penalties
Fines reach up to €35 million or 7% of global annual revenue for prohibited practices, up to €15 million or 3% for other violations, and up to €7.5 million or 1% for supplying incorrect information.
Practical Steps
Inventory all AI systems, classify by risk category, document data sources and training procedures, implement logging for AI decisions, establish human oversight procedures, create incident response plans, and train staff on compliance requirements. High-risk compliance typically takes 12–18 months — start now if you have not already.
For Beginners
The EU AI Act is a law that regulates AI systems based on risk level. If your company uses AI tools in the EU, you need to figure out which risk category your tools fall into. The highest-risk categories have the strictest rules and the biggest fines.
For Practitioners
The August 2, 2026 deadline for high-risk AI is the critical date. GPAI model obligations have been in force since August 2025. Penalties for GPAI model providers are deferred but approaching. Align AI Act compliance with GDPR governance — they share overlapping requirements for personal data processing, logging, and impact assessments.
