From source to evidence

Why this obligation applies, what it asks of you, and what you show for it.

Applies

Applicable · 2 August 2026

For whom

Deployer
Provider of an AI system

What you do

Implement the applicable disclosure, marking or label

What you record

Transparency implementation record

Official source

Article 50(1)-(5) and Article 113

Who this is relevant to

When this applies

Deployer
An organisation using an AI system under its authority, excluding personal non-professional use.
Provider of an AI system
A party that develops or has an AI system developed and places it on the market under its own name.

1An AI system is intended to interact directly with natural persons.
2The system generates or manipulates synthetic audio, image, video or text, or the use concerns a specifically listed deployer scenario.

What the official source establishes

Article 50 applies since 2 August 2026. The precise duty differs by scenario: direct AI interaction, machine-readable marking, emotion recognition or biometric categorisation, deepfakes and certain public-interest text.

Our interpretation

The official source remains authoritative. This general interpretation is not legal advice.

A generic rule that all AI content must always carry a visible label is too broad. First classify the specific Article 50 scenario.

What you can do now

For each system, record the applicable paragraph, responsible actor, implemented disclosure or marking and how it was tested.

01
Implement the applicable disclosure, marking or label
First determine which paragraph of Article 50 applies, then implement the specific transparency measure.

What to retain

Transparency implementation record

Record of scenario, actor, disclosure or marking, technical implementation, test and owner.

Control and reassessment

Pre-release transparency check
Before release, test that the applicable disclosure, marking or label is timely, clear and technically effective.

Public tools

Open public transparency template

Conditions and exceptions

The direct-interaction disclosure is not required where this is obvious to a reasonably well-informed, observant and circumspect person, considering circumstances and context.
Only Article 50(2) has a transition until 2 December 2026 for systems placed on the market before 2 August 2026.
