2 August 2026: Article 50 Transparency Rules and GPAI Enforcement Powers Go Live

While the Digital Omnibus pushed most high-risk deadlines into 2027 and 2028, it deliberately left one date in place: 2 August 2026. On that day the EU AI Act's Article 50 transparency obligations take legal effect across every Member State simultaneously, and the European Commission's enforcement powers over general-purpose AI (GPAI) model providers come fully online.

Article 50 is not limited to high-risk systems. It applies to any AI system that falls into the four situations the Article covers: systems that interact directly with people must disclose that a person is dealing with an AI; providers of generative systems must mark synthetic audio, image, video and text in a machine-readable, detectable way; and deployers of deepfakes and of AI-generated text published to inform the public must disclose the artificial origin. In practice, that reaches almost every organisation using generative AI to produce content.

The teeth arrive the same day. From 2 August 2026 the Commission can open formal investigations, issue binding corrective measures, and impose fines on GPAI providers and on entities that breach Article 50. Non-compliance with the transparency rules can attract fines of up to €15,000,000 or 3% of total worldwide annual turnover for the preceding financial year, whichever is higher.

There is one narrow relief. AI systems already placed on the market before 2 August 2026 benefit from a four-month grace period — until 2 December 2026 — before the Article 50(2) synthetic-content marking obligation bites on them. New systems get no such runway.

For most deployers the practical work is short but real: inventory every place generative AI touches a customer or the public, wire in the interaction disclosures, and confirm your model vendors emit detectable content marking. Veritome surfaces the Article 50 obligations automatically for every system whose classification triggers them, with the disclosure text and evidence slots attached.
