The duty
Providers ensure that AI systems intended to interact directly with people are designed so that those people know they are interacting with an AI system, unless this is obvious to a reasonably well-informed, observant person [1]. This duty has applied since 2 August 2026 [2].
Who bears the duty
Article 50(1) is addressed to the provider. A provider is anyone who develops an AI system, or has one developed, and puts it into service under their own name or trademark [3]. If you use a supplier's chatbot, Article 50(1) does not put that duty on you, but do check that the chatbot gives the notice. If you build a chatbot yourself on a third party's model and put it on your jobs site, you are the provider and the notice is your duty.
