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
Objective: enable people to distinguish AI systems and AI-generated content.
Interacting with AI
People shall be informed when they interact directly with an AI system.
Marked, detectable content
Content generated or manipulated by an AI system shall be marked and detectable.
Emotion & biometrics
People exposed to emotion recognition or biometric categorisation systems shall be informed.
Deepfakes & public-interest text
Deepfakes and AI-generated text publications on matters of public interest shall be labelled.
Information shall be provided in a clear and distinguishable manner, at the latest at the first interaction or exposure (Art. 50(5)).
