Article 21: cooperation with competent authorities

Upon a reasoned request by a competent authority, the provider of a high-risk AI system provides all the information and documentation necessary to demonstrate conformity with the requirements of Chapter III, Section 2, in a language which can be easily understood by the authority in one of the official languages of the institutions of the Union as indicated by the Member State concerned. Upon the same request the provider also gives, as applicable, access to the automatically generated logs, to the extent those logs are under its control.

The legal path

Source ·: Article 21 on EUR-Lex
Condition ·: Applies to providers of high-risk AI systems as soon as a competent authority makes a reasoned request. For the standalone Annex III route (Article 6(2)) the date is 2 December 2027. For systems that are high-risk under Article 6(1) and relate to products covered by Annex I, Section A, the date is 2 August 2028. For products covered by Annex I, Section B, Article 21 does not apply at all: amended Article 2(2) makes only Article 6(1), Article 60a and Articles 102 to 112 applicable there, and Article 21 is not on that list. That is not a corner case, because the Machinery Regulation (EU) 2023/1230 has been moved from Section A to Section B. Note also the new Article 2(13): for systems under Annex I, Section A, the Commission may limit the application of Articles 17 to 25, and therefore of Article 21, by delegated act.
Condition ·: For systems already running, the amended Article 111(2) applies: without prejudice to the application of Article 5 as referred to in Article 113, third paragraph, point (a), the Regulation applies to operators of high-risk AI systems, other than those referred to in Article 111(1), placed on the market or put into service before the date of application of Chapter III referred to in Article 113, only if, as from that date, those systems are subject to significant changes in their designs. The reference date is therefore no longer 2 August 2026 but whichever date applies to the system: 2 December 2027 for the Annex III route and 2 August 2028 for the Annex I route. For systems intended to be used by public authorities the date of 2 August 2030 applies in any case.
Exception ·: Paragraph 2 carries two limits, not one. Access to the automatically generated logs applies "as applicable", and it applies "to the extent such logs are under their control". Logs held solely by the deployer therefore fall outside what the provider can supply under this Article; the deployer keeps those logs itself under Article 26(6).
