EU AI Omnibus: What the Delay Does Not Cover

Brussels pushed high-risk AI deadlines to December 2027, but transparency duties under Article 50 stayed put. Vendors are already blurring the two.

What happened: 27 July 2026 · Written: 31 August 2026

The short answer

The EU delayed its high-risk AI rules from August 2026 to December 2027, but transparency duties under Article 50 still start 2 August 2026. If you sell AI into the EU, disclosure and content-marking work stays on the original clock.

What the Omnibus actually moved

The AI Omnibus entered into force across the EU on 27 July 2026. It was proposed on 19 November 2025 as part of the wider digital omnibus package, and the Commission describes it as a targeted simplification of the AI rulebook rather than a retreat from it. The headline change is timing: obligations for stand-alone high-risk systems listed in Annex III now apply from 2 December 2027, and high-risk AI embedded in physical products under Annex I applies from 2 August 2028.

Those two dates are the only new deadlines the Commission’s own announcement sets out. Everything else you may have read about what was postponed comes from reading the change against the AI Act’s original schedule, not from the Omnibus page itself. That distinction matters when a vendor tells you compliance has been pushed back, because the claim is broader than the document supports.

Independent legal analysis lines up with the official text. Gibson Dunn reads the agreement the same way, confirming that high-risk obligations for stand-alone Annex III systems are deferred to 2 December 2027. There is no dispute about the dates. The dispute, where there is one, is about what buyers should infer from them.

Article 50 did not move

The transparency obligations in Article 50 apply from 2 August 2026 and were not extended. The Commission’s own FAQ on the provision is explicit that from that date providers and deployers of AI systems must comply. Goodwin’s alert confirms the practical position: on 2 August 2026 those obligations became generally applicable and enforceable by national competent authorities across the EU. The high-risk delay does not touch them.

There is one narrow exception, and it is worth knowing before a vendor overstates it. A limited grace period applies only to the marking and detection obligation for AI-generated content under Article 50(2), and only for systems placed on the market before 2 August 2026. Providers of those systems must comply from 2 December 2026. Content produced before 2 August 2026 does not need retroactive labelling.

So the picture is split. If your supplier’s product touches chatbots, synthetic media, emotion recognition or biometric categorisation, the disclosure duties are live now. If the product is a hiring screen, a credit scorer or another Annex III use case, the compliance file is not due until December 2027. Same regulation, two very different clocks.

What this changes for buyers

The delay removes near-term pressure on vendors, and that cuts both ways. A supplier that was scrambling to document a high-risk system now has an extra sixteen months, which means the conformity evidence you might have expected in a 2026 procurement round may simply not exist yet. Asking for it is still reasonable. Accepting its absence without a dated commitment is not, because the deadline has moved once already.

Watch for vendors who fold the whole regulation into one reassuring sentence. If a sales deck says EU AI Act obligations have been postponed to 2027, that statement is wrong about Article 50 and may be wrong about your specific use case. Ask which annex the system falls under, and ask separately about transparency duties. The two answers should not be the same answer.

The unknown worth flagging: a deadline extended once can be extended again, and it can also be enforced harder to compensate. Nobody selling you software knows which way that goes. Treat 2 December 2027 as a planning date rather than a settled fact, and keep the evidence trail going in the meantime rather than pausing it.

What to do about it

Split your vendor questionnaire in two. Ask which annex each AI system falls under, so you know whether December 2027 or August 2028 applies, and get a dated commitment for the conformity evidence. Then ask separately how the vendor meets Article 50 transparency duties, which have been enforceable since 2 August 2026. Reject any answer that collapses both into a single 2027 date.

Questions readers ask

When do EU AI Act high-risk rules now apply?

Stand-alone high-risk systems listed in Annex III apply from 2 December 2027. High-risk AI embedded in physical products such as machinery, toys and lifts, covered by Annex I, applies from 2 August 2028. Both dates come from the European Commission’s own announcement of the AI Omnibus, which entered into force on 27 July 2026.

Were Article 50 transparency obligations delayed too?

No. Article 50 applies from 2 August 2026 and was not extended. One narrow grace period exists: the marking and detection obligation for AI-generated content under Article 50(2) applies from 2 December 2026, but only for systems placed on the market before 2 August 2026. Content generated before that date needs no retroactive labelling.

What should I ask an AI vendor selling into the EU?

Ask two separate questions. First, which annex their system falls under, since that sets whether the deadline is December 2027, August 2028 or neither. Second, how they meet Article 50 transparency duties, which are already enforceable. A vendor that answers both with one date about 2027 has not understood the split.
