The short answer
Since 2 February 2025 certain AI practices are banned and companies must ensure AI literacy among their staff. Since 2 August 2026 the Article 50 transparency duties apply: chatbots must disclose that they are AI, AI-generated content must be marked in a machine-readable way and deepfakes must be disclosed. For systems already on the market before that date, the marking deadline is 2 December 2026. After the Digital Omnibus, obligations for Annex III high-risk AI apply only from 2 December 2027.

Fines under Article 99
| Infringement | Maximum |
|---|---|
| Prohibited practices (Art. 5) | EUR 35 million or 7% of worldwide annual turnover |
| Other obligations, including transparency (Art. 50) | EUR 15 million or 3% of worldwide annual turnover |
| Incorrect or misleading information to authorities | EUR 7.5 million or 1% of worldwide annual turnover |
The higher amount applies. For small and medium-sized enterprises, the lower of the two applies.
Frequently asked questions about the EU AI Act
Does the AI Act apply if we only use ChatGPT or other AI tools?
Yes. Anyone using AI systems professionally is a deployer. Deployers must at least ensure AI literacy under Art. 4 and, depending on use, meet Art. 50 transparency duties, for example when publishing deepfakes.
Must AI-generated images be labelled?
Providers of systems that generate images, video, audio or text must mark them in a machine-readable way (Art. 50(2)). Anyone publishing realistic images of real people, places or events must also disclose that they are artificially generated (Art. 50(4)).
Were the AI Act deadlines postponed?
Partly. With the Digital Omnibus of summer 2026, obligations for Annex III high-risk AI apply from 2 December 2027 and for AI in regulated products from 2 August 2028. The transparency duties still apply since 2 August 2026.
What does AI literacy under Article 4 mean?
Companies that provide or use AI must take measures so that their staff use AI competently and understand its opportunities and risks. In practice: training and short documentation.
Is AI allowed for candidate screening?
Yes, but it counts as high-risk AI under Annex III. From 2 December 2027, duties such as human oversight, logging and informing affected people apply. Emotion recognition at work, however, is banned.
How high are the fines?
Up to EUR 35 million or 7% of worldwide annual turnover for prohibited practices and up to EUR 15 million or 3% for other obligations. For SMEs the lower amount applies (Art. 99).
