What is high-risk AI?
High-risk AI is one of the risk categories defined in the EU AI Act. It encompasses AI systems that can have significant impacts on health, safety, or fundamental rights—for example, in human resources, education, the legal system, border control, or critical infrastructure.
The EU AI Act distinguishes four risk classes: Prohibited (e.g., social scoring), High Risk, Limited Risk (e.g., chatbots subject to transparency requirements), and Minimal Risk.
High-risk AI is subject to numerous obligations: risk management, data quality, technical documentation, transparency, human oversight, robustness, and cybersecurity. Providers and operators share responsibility.
For small and medium-sized enterprises, the classification as high-risk is important—many HR, financial, and credit applications fall into this category. Clarifying this early on saves costly rework.
Best Practices for High-Risk AI
These six principles have proven effective:
- Start early: Compliance takes months—don’t wait until right before the deadline to begin.
- Build cross-functionally: IT, Legal, Compliance, and the business unit must work together.
- Document pragmatically: Use templates and guidelines—don’t reinvent the wheel every time.
- Leverage GDPR synergies: Continue to use existing data protection structures.
- Continuous oversight: Compliance is not a static state, but a process.
- Supplier management: For purchased AI systems, require proof of compliance in the contract.
Common Mistakes in High-Risk AI
We frequently encounter these pitfalls:
- Underestimated classification: The system is not identified as high-risk—leading to a rude awakening during the audit.
- IT-Only Perspective: Business units and legal departments are not involved—critical requirements are missing.
- No risk management process: Ad hoc assessments instead of continuous oversight.
- Third-party AI not verified: Responsibility remains with the operator—vendor documentation is mandatory.
- Bias ignored: Data quality and fairness are key requirements—not a minor issue.
Provider vs. Operator vs. User
Three roles in the AI Act with different obligations:
- Provider: Develops and brings an AI system to market. Highest obligations (documentation, conformity assessment).
- Operator: Uses the AI system in their own operations—e.g., HR software with AI. Operational obligations.
- Users: Interact with the system (e.g., job applicants). Right to information and to file a complaint.
