Key deadline

Under the amended EU AI Act, **providers of AI systems that generate synthetic audio, images, video or text and were placed on the market before 2 August 2026 must fulfil the marking and detection obligations of Article 50 (2) by 2 December 2026Source.

The same FAQ states that transparency obligations become enforceable from 2 August 2026, but the compliance window for earlier‑marketed systems extends to 2 December 2026.

Current status

No official amendment or postponement of this deadline has been published on the AI Act Service Desk or any other EU source up to the present date. Therefore, the legally applicable compliance deadline remains 2 December 2026.

Uncertainty & monitoring

  • The information is based on the AI Act Service Desk FAQ (accessed 4 Nov 2026). Future legislative changes could alter the deadline.
  • Stakeholders should monitor the EU’s AI Act updates and any formal amendments published in the Official Journal of the European Union.
