The AI Act classifies AI applications by risk. In addition, there are separate rules for the large AI models themselves.
1. Unacceptable risk: prohibited
Since 2 February 2025, a limited list of applications has been prohibited (Article 5). These include:
- Manipulation or deception that can cause people harm
- Exploiting vulnerabilities, for example due to age or a disability
- Social scoring: assessing people on their behavior or personality, with adverse consequences
- Collecting facial images in an untargeted way for facial recognition
- Emotion recognition in the workplace and in education, with some exceptions
For an average SME, the chance that you do any of this is small. Do check it, especially with tools that analyze employees or customers.
The Digital Omnibus added a prohibition on AI systems that create non-consensual intimate images or child sexual abuse material. That prohibition applies from 2 December 2026.
2. High risk: strict requirements
High risk covers AI systems that are a safety component of products with their own European rules, such as medical devices, machinery and toys (Annex I). And AI systems in sensitive applications (Annex III), including:
- Work and staff: recruitment and selection, evaluating, promoting, dismissing, allocating tasks and monitoring
- Education: admission, assessment and monitoring during tests
- Access to essential services, such as creditworthiness assessment
- Biometrics, critical infrastructure, law enforcement, migration and the administration of justice
Not everything in those domains is automatically high risk. If a system only performs a narrow, preparatory task and doesn't materially influence the decision, it may fall outside it (Article 6). If the system profiles people, that exception doesn't apply. If in doubt, have a lawyer assess it.
3. Limited risk: transparency
Transparency rules apply to chatbots, deepfakes and AI-generated content (Article 50). People need to know that they're talking to AI or looking at AI content. Those rules have applied since 2 August 2026.
4. Minimal risk: no new rules
Spam filters, AI in games, a tool that summarizes your email or drafts a quote: most applications in an average business fall here. No additional requirements apply to them, apart from the AI literacy measures that apply to every organization.
And the large AI models?
Since 2 August 2025, the makers of general-purpose AI models, such as OpenAI, Google and Anthropic, have had their own rules. Those rules are for them, not for you as a user.
