EU AI Act Transparency Rules Take Effect

New transparency obligations under the AI Act's Article 50 became applicable across the EU. AI systems generating synthetic audio, image, video or text must now mark outputs in a machine-readable, detectable format; chatbots and other interactive AI systems must disclose that users are interacting with AI rather than a human; and deepfakes must be labelled. The AI Office can request technical documentation, evaluate general-purpose AI models, require corrective measures and fine non-compliant developers. Under the AI Omnibus adopted in June, generative AI systems already on the market before August 2 have until December 2, 2026 to meet the machine-readable marking requirement.
