European Union: the EU AI Act (post-Omnibus)
The EU AI Act (Regulation 2024/1689) is the world's first comprehensive AI law, using a four-tier risk model from banned practices through high-risk to minimal-risk uses. Following the Digital Omnibus, in force since 27 July 2026, the high-risk timeline shifted: Annex III obligations (employment, credit, essential services and more) now apply from 2 December 2027, and Annex I regulated-product rules from 2 August 2028. Article 50 transparency duties, telling users they are interacting with AI and labelling AI-generated content, have applied since 2 August 2026; generative systems already on the market before then have until 2 December 2026 to add machine-readable watermarking. SMEs benefit from reduced documentation, proportionate fines and free regulatory-sandbox access. Norway is bringing in the same rules through the EEA with its own AI Act, although adoption is running behind the EU timetable, and members like France (CNIL), Germany (DSK guidance and works-council rights), Italy (its national AI law) and Spain (the AESIA agency) layer national measures on top.
