EU AI Act to require machine-readable marking on older generative AI

EU Artificial Intelligence Act. The EU's horizontal AI law. It bans some AI practices, sets duties for high-risk AI systems and for general-purpose AI models, and sets transparency duties for systems that interact with people or make synthetic content.
