- Since February 2025: AI literacy (Art. 4) and prohibitions (Art. 5).
- Since 2 August 2026: transparency obligations, e.g. for chatbots (Art. 50).
- High-risk obligations under Annex III: postponed to December 2027 by the digital omnibus.
The EU AI Act applies in stages, and in 2026 it affects almost every company that uses AI. The key obligations today: your staff need sufficient AI literacy, prohibited AI practices are off-limits, and since 2 August 2026 chatbots must identify themselves as AI. The strict rules for high-risk systems come later, but should be planned for now.
What has applied since February 2025
Since 2 February 2025, certain AI practices have been prohibited, such as manipulative systems that exploit people's vulnerabilities, or social scoring. At the same time, Art. 4 requires providers and deployers of AI systems to take measures to ensure sufficient AI literacy among their staff. This also applies to a company that only uses AI tools such as chatbots or writing assistants.
What has applied since 2 August 2026
Since 2 August 2026, the transparency obligations of Art. 50 apply. Particularly relevant for companies:
- Chatbots and other AI systems that interact directly with people must be designed so people can tell they are interacting with AI, unless that is obvious.
- Deepfakes must be disclosed as artificially generated.
- AI-generated text published to inform the public on matters of public interest must be labelled, unless a person has reviewed it editorially and bears responsibility.
For machine-readable marking of AI-generated content by the providers of such systems, the digital omnibus sets 2 December 2026.
High-risk systems: later, but not forgotten
AI systems in sensitive areas such as recruitment, credit scoring or critical infrastructure are considered high-risk. The obligations for the high-risk systems in Annex III have been postponed by the digital omnibus to 2 December 2027. If you already use AI in recruitment, for example, start now with documentation, risk assessment and human oversight.
