Provider or deployer?
The AI Act gives duties to roles. A provider develops an AI system or a general-purpose AI model, or has it developed, and places it on the market or puts it into service under its own name or trademark, whether paid or free. A deployer uses an AI system under its own authority, except for purely personal, non-professional use. One company can be both. See Article 3.
AI literacy (Article 4)
Providers and deployers of AI systems must take measures to support AI literacy among staff and others who operate and use the systems on their behalf. The amended text adds that this does not require guaranteeing a particular level of literacy for any individual. Article 4 has applied since 2 February 2025; the wording above is the amended text. See Article 4.
Transparency (Article 50)
- Systems that interact directly with people must let them know they are dealing with an AI system, unless that is obvious.
- Systems that generate synthetic audio, images, video or text must mark their output in a machine-readable way, so it can be detected as artificially generated or manipulated.
- Deployers of emotion recognition or biometric categorisation must inform the people affected.
- Deployers who create deepfakes must disclose it, and so must those publishing AI-generated text to inform the public on matters of public interest, unless it has had human review and someone holds editorial responsibility.
Article 50 applies from 2 August 2026. Generative systems already on the market before then have until 2 December 2026 for the marking duty. See Article 50.
General-purpose AI models
If you provide a general-purpose AI model, you have duties of your own, including a copyright policy and a public summary of training content. See the training data summary and fine-tuning and the provider role.
High-risk systems
High-risk systems have the strictest rules, including data governance under Article 10. See is my AI system high-risk?
Where training data fits
Even where the Act sets no data rules for your system, knowing what is in your training data helps you answer customers, explain your model and meet the duties above. This guide is general information, not legal advice.
