Article 50 Check · by Ninth Harbor

What is the December 2026 grace period?

Marking only — not disclosure or labelling

Under the Digital Omnibus, generative systems already on the market before August 2, 2026 get an extension to December 2, 2026 for one specific element: the machine-readable marking duty under Article 50(2).

That's it — the grace period is narrow, and it's easy to over-read it as covering more than it does. It does not extend the Article 50(1) chatbot disclosure duty. It does not extend the Article 50(4) published-content labelling duties (deepfake or AI-text labelling). Both of those still apply from August 2, 2026, full stop, regardless of when your system went live.

It also only applies to the specific duty of marking outputs as machine-readable — not to the parallel requirement to provide a detection means, which some read as a separate, cumulative element (§§65–73 of the draft guidelines describe marking and detection as two cumulative pieces).

One more qualifier, and it's an important one: this grace period is binding only once the Digital Omnibus is formally published in the Official Journal of the European Union. As of this writing, the European Parliament adopted the provisional agreement on June 16, 2026, but Official Journal publication was still pending. Treat this grace period as expected but not yet legally locked in — re-verify at the point you plan to rely on it, ideally close to your actual deadline.

The date itself — December 2, 2026 — is easy to conflate with the separate, much larger delays the same Digital Omnibus applied to the high-risk-system rules (Annex III use cases to December 2, 2027, a full year later; Annex I to August 2, 2028). Those are a different framework entirely, covering a different set of duties, and shouldn't be read across into how long you have for anything under Article 50.

For most SME buyers, the practical relevance is limited: the grace period only matters if you're a provider of a generative system under Article 50(2), which most SMEs using AI tools — rather than building and branding a generative product — are not.

A useful way to check whether this grace period is even relevant to you: do you develop and offer, under your own brand, a system whose job is generating audio, image, video, or text for other people to use? If the honest answer is no — you're using ChatGPT, Midjourney, or a similar tool inside your own workflow rather than reselling generation as a product — this grace period, and the underlying marking duty it extends, doesn't apply to you at all, regardless of what date your systems went live.
