Who can sign?
Any provider or deployer of a generative AI system subject to Article 50(2) or (4).
Provider
Develops an AI system — 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 of charge.
Example: a company offering a chatbot or image generator under its brand, or one that develops a generative AI system in-house and puts it into service.
Deployer
Uses an AI system under its authority in a professional activity: it owns the decision to deploy the system and the manner of its use, including its outputs.
Example: a media outlet whose editors publish AI-assisted text on matters of public interest on its website.
What Article 50 requires
That people can tell AI systems and AI-generated content apart.
Interacting with AI
People must be informed when they interact directly with an AI system.
Marked, detectable content
Content generated or manipulated by an AI system must be marked and detectable.
Emotion and biometrics
People exposed to emotion recognition or biometric categorisation systems must be informed.
Deepfakes and public-interest text
Deepfakes and AI-generated text published on matters of public interest must be labelled.
The information is given in a clear and distinguishable manner, at the latest at the first interaction or exposure (Art. 50(5)).
Five steps
From adding your first system to sending the signed form.
- 01
Add your generative AI systems to the inventory
Register each system in the inventory: intended purpose, department and owner. Everything else builds on it.
- 02
Determine your role
The guided assessment classifies each system and determines whether you act as provider or deployer, and which transparency obligations apply to you.
- 03
Trigger the transparency milestone
Aithority generates the Article 50 milestone with the required evidence and the signatory form pre-filled with your organisation’s details.
- 04
Download and sign the form
Download it as a PDF and sign it. It must be signed by a person with sufficient authority to bind the organisation — for instance, a senior executive.
- 05
Send it to the AI Office
Send the signed form to the European AI Office mailbox:
CNECT-AIOFFICE-CODE-OF-PRACTICE-TRANSPARENCY@ec.europa.eu
