# Transparency (Art. 50)

> Telling people they interact with AI, marking AI-generated content, disclosing deepfakes and AI-generated public-interest text.

Since 2 August 2026, Art. 50 sets transparency duties for AI that talks with people or makes content. They apply whatever the risk class of the system.

## The duties, case by case

| Case | Who | What |
|---|---|---|
| AI that interacts with people, such as a chatbot | Provider | Design it so people are told they are interacting with AI, unless it is obvious (Art. 50(1)) |
| AI that generates audio, images, video or text | Provider | Mark the output in a machine-readable way as artificially generated (Art. 50(2)) |
| Emotion recognition or biometric categorisation | Deployer | Inform the people exposed to it (Art. 50(3)) |
| Deepfakes | Deployer | Disclose that the content was artificially generated or manipulated (Art. 50(4)) |
| AI-generated text published to inform the public on matters of public interest | Deployer | Disclose it, unless a person reviewed it and someone holds editorial responsibility (Art. 50(4)) |

## Older systems: marking by 2 December 2026

AI systems placed on the market before 2 August 2026 must comply with the marking duty of Art. 50(2) by 2 December 2026 (Art. 111(4) as amended).

## Guidance

The Commission published guidelines on Art. 50 on 22 July 2026. A voluntary code of practice on marking and labelling AI-generated content dates from 2 July 2026.
