Drafted with AI help and checked against the official EU text before publishing.

Some duties are already in force. AI literacy (Article 4) applied from 2 February 2025. The transparency rules in Article 50 apply from 2 August 2026. Extra high-risk rules were put back to 2027 and 2028.

Extra high-risk rules in Chapter III were put back to 2 December 2027 and 2 August 2028 by the Digital Omnibus on AI. Those later dates are extra time for high-risk systems. They do not pause Article 4 or Article 50.
