  • Lithuanian implementing law. In the Seimas since 9 June 2026, aimed at adoption before 2 August 2026 — that date has now passed without a confirmed adoption on record here. Article 50 binds you regardless: the national law sets enforcement details, not the duty. [lrs.lt]

    Regulation (EU) 2024/1689 — the AI Act, full textEUR-Lex

    The law itself, in all EU languages. It is a regulation — directly applicable in every member state, no national transposition needed for it to bind you.

    Article 50 — transparency obligationsAI Act Explorer

    The article behind this scanner: people must be told when they interact with an AI system, and certain AI-generated content (deep fakes, and AI-written text published on matters of public interest) must be disclosed as such. Annotated per-paragraph view.

  5. 05
    Guidelines on transparency obligations for providers and deployers of certain AI systemsEuropean Commission

    The final Article 50 guidelines, published 20 July 2026 — the Commission's own reading of what counts as adequate disclosure. Non-binding, but it is what a market-surveillance authority reaches for first.

  6. 06
    Code of Practice on Transparency of AI-Generated ContentEuropean Commission

    Voluntary code (final version 10 June 2026) describing how signatories mark and disclose AI-generated content in practice. Sections may be signed separately — a deployer that only publishes AI-generated content signs Section 2 — and the code stays open for signature.

  7. 07
    Regulation (EU) 2026/1744 — Digital Omnibus on AIEUR-Lex

    The amending regulation of 8 July 2026, in the Official Journal since 24 July 2026. It is the legal basis for the postponed high-risk dates and the marking grace period below — Article 50's own date it left untouched.

What changed, and when we logged it

2026-09-13
Re-verification, no date changed. Re-read EUR-Lex for Regulation (EU) 2024/1689 and Regulation (EU) 2026/1744 (act of 8 July 2026, Official Journal 24 July 2026, Article 50(2) marking due 2 December 2026, high-risk dates 2 December 2027 and 2 August 2028), the Commission guidelines page and its library record (publication 20 July 2026), the Code of Practice page (final code 10 June 2026, about 190 signatories by the end of July 2026) and the signing FAQ (27 July 2026 18:00 CEST closed only the initial-signatories list; signing stays open). Two wordings tightened: the Article 50 summary no longer says people are told whenever they see AI-generated content, because Article 50(2) is a provider marking duty and Article 50(4) covers deep fakes and public-interest text. The Lithuanian implementing law could not be re-checked: the lrs.lt search portal renders results client-side, so that entry stands as unconfirmed.
2026-08-04
Correction. Re-checked against the primary sources; four entries had been overtaken by events and are fixed above. (1) The Code of Practice was shown as closing to signature on 22 July 2026 — wrong date and wrong substance: 27 July 2026 18:00 CEST closed only the list of initial signatories, and the code itself remains open for signature. (2) The Commission's Article 50 guidelines were listed as still awaited; they were published 20 July 2026. (3) The Commission and AI Board adequacy conclusions of 8 and 9 July 2026 were missing entirely. (4) The Digital Omnibus was shown as awaiting the Official Journal; it appeared there on 24 July 2026.
2026-07-24
Digital Omnibus on AI published in the Official Journal as Regulation (EU) 2026/1744, entering into force on the third day after publication. The marking grace period and the high-risk postponements are now black-letter law, not an adopted draft.
2026-07-20
European Commission published the final guidelines on Article 50 transparency obligations — thirteen days before the obligations began to apply. Non-binding, but they define the disclosure practice regulators will measure against.
2026-07-14
Watch page published. Every date above verified against the primary texts (EUR-Lex, EP adopted text T10-0198/2026, Commission digital-strategy pages).
2026-07-09
Adequacy settled: on 8 July 2026 the European Commission, and on 9 July 2026 the AI Board, concluded that the Code of Practice on Transparency of AI-Generated Content is an adequate voluntary tool for implementing Article 50(2), (4) and (5). Signing it is evidence of good faith — it is not a certificate, and it does not replace the obligation.
2026-07-08
Digital Omnibus signed. Article 50 dates unchanged; a marking grace period until 2 December 2026 added for pre-existing generative systems (new Art. 111(4)); high-risk dates postponed to 2027/2028.
2026-06-10
Final Code of Practice on Transparency of AI-Generated Content published by the Commission; open for voluntary signature from that day on, with a cut-off only for inclusion in the initial signatories list (corrected 2026-08-04 — this entry originally stated a closing date).

What people ask about Article 50

Does Article 50 apply to my website?

It binds providers and deployers of AI systems in scope, for example a chatbot that talks to visitors (Art. 50(1), a provider duty) or AI-generated text published to inform the public on matters of public interest (Art. 50(4), a deployer duty). Whether you are a provider or a deployer of your particular setup is a judgement for you and your advisers; this page gives you the dates and the primary texts to make it with.

What changed on 2 August 2026?

The Article 50 transparency obligations started to apply. The Digital Omnibus (Regulation (EU) 2026/1744, in the Official Journal since 24 July 2026) postponed several high-risk dates but left Article 50's date untouched. Penalties reach €15 million or 3 % of worldwide annual turnover, whichever is higher; for SMEs, whichever is lower.

Is signing the Code of Practice mandatory, and can we still sign?

It is voluntary and it remains open: providers and deployers may sign at any time, including after 27 July 2026. That date closed only the list of initial signatories published before 2 August 2026. Sections can be signed individually: a deployer that publishes AI-generated content signs Section 2.

Do the Commission guidelines make anything binding?

No. The guidelines published on 20 July 2026 are non-binding, but they set out how the Commission reads Article 50, which is what a market-surveillance authority reaches for first. The Commission and the AI Board also concluded, on 8 and 9 July 2026, that the Code of Practice is an adequate tool for implementing Article 50(2), (4) and (5).

Scope of this page

An information service: dates and documents summarised from official sources, each entry linked so you can verify it yourself. It is not legal advice, and a summary never overrides the linked text. What Article 50 means for your specific setup is a judgement for you and your advisers.
