Chatbots operating across the European Union must now tell users they are talking to a machine, not a person. AI-altered images, video and audio also require clear labelling, under new transparency rules that took effect on Sunday.
The obligations form part of the bloc's Artificial Intelligence Act, which the Council of the EU has called the world's first law on artificial intelligence. From 2 August, the European Commission's AI Office, working alongside national authorities, also gained the power to enforce it.
