The Digital Omnibus moved the Annex III high-risk obligations from August 2026 to 2 December 2027. What that date covers, and why the old one still circulates.
This whole series explains obligations that don't fall on you because they belong to the provider. Article 25 says when they do — and there are three closed-list circumstances, not a grey area.
Article 73 requires the provider of a high-risk system to report serious incidents. Under Article 26(5), the deployer informs first the provider and then the importer or distributor and the authority; if it cannot reach the provider, Article 73 applies to it mutatis mutandis.
Article 72 requires the provider to establish a post-market monitoring system. The deploying company doesn't build it, but Article 26(5) requires it to monitor operation, inform in accordance with that article and, where applicable, suspend use.
Article 21 — cooperation with the authorities — binds providers, and sets no deadline. What reaches the deployer is Article 26(12). The difference changes what can be demanded of you, and what can't.
Annex IV turns up on task lists for companies deploying AI. It imposes nothing on anyone: it specifies what the technical documentation Article 11 requires from the provider must contain.
The difference between the two classifications isn't one of degree. A minimal-risk system is resolved with Article 4. A high-risk one opens the whole of Article 26, and none of its obligations is met on its own.
Article 18 requires five documents to be kept for ten years from the moment the system is placed on the market. All five are produced or received by the provider, and the clock starts from an event the deploying company had no part in.
A system holds the record, the relationships between decisions, and detection of what has expired. It does not hold the decision or the accountability. The line is sharp, and it's worth knowing where it falls before you buy anything.
Article 17 requires a documented quality management system for high-risk AI systems. It applies to providers, and its content is about product design and development — nothing a deploying company can put in place.
