Transparency obligations (Article 50)
In a nutshell
The rules requiring people to be told when they are talking to an AI or seeing AI-generated content, such as chatbots, deepfakes or synthetic text.
Article 50 covers limited-risk systems: they are not dangerous, but people have a right to know AI is involved. It applies from 2 August 2026. The main obligations are:
- Chatbots and assistants must tell users they are interacting with an AI, unless it is obvious.
- Providers of systems that generate audio, images, video or text must mark that content in a machine-readable way so it can be detected as artificial.
- Deployers of emotion recognition or biometric categorisation must inform the people exposed.
- Whoever publishes deepfakes must disclose that the content is artificial.
- Whoever publishes AI-generated text on matters of public interest must disclose it, unless there is human review and editorial responsibility.
For generative systems already on the market before 2 August 2026, the marking deadline was extended to 2 December 2026.
