The AI Act timetable
The EU AI Act, Regulation (EU) 2024/1689, applies in stages. The bans on prohibited AI practices and the AI literacy provision have applied since 2 February 2025, the rules for general-purpose AI models since 2 August 2025, and most of the remaining provisions, including the transparency obligations, since 2 August 2026; generative AI systems placed on the market before that date have until 2 December 2026 to meet the marking obligation of article 50(2), and new prohibitions added in 2026 apply from the same date. Following Regulation (EU) 2026/1744, the obligations for high-risk AI systems now apply from 2 December 2027 for the uses listed in Annex III and from 2 August 2028 for AI embedded in products covered by Annex I.
In Greece, Law 5321/2026 introduced measures for the application of the AI Act and repealed the earlier national obligations of Law 4961/2022 for private companies using AI systems. Contracts with AI suppliers should therefore be written against the AI Act itself.
