AI system

The gateway definition of the Regulation's system track: if your application falls outside it, the obligations for AI systems do not apply. General-purpose AI models run on a separate track under Article 3(63), with their own obligations in Article 53.

The official source remains authoritative. This is general information about obligations and not legal advice. See this object on the map

What this object links to

Every relation appears below as a path: from the source with its locator, through the conditions and exceptions of the object carrying the relation, to the consequence. A locator belongs to a statement in the data and not to a relation, so the source is the source anchor of the carrying object.

What this object states

Official fact

Attributable to a named primary source, with a locator. Where they differ, the official source prevails.

Article 3(1) defines an AI system as a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.

Our interpretation

Our own reading. It can change without the law changing, and it is not the position of a supervisory authority.

Two mirror-image errors. First, treating only generative AI and language models as AI systems, which leaves classic scoring models, matching algorithms and predictive models out of the register even though they clearly infer how to generate outputs. Second, calling every piece of software AI, which makes the register useless. The hinge is the word infers: a system that merely executes a rule written by a human infers nothing. Note also the word may in may exhibit adaptiveness: adaptiveness after deployment is a possibility, not a condition. A model frozen after training is still an AI system.

Recommended step

A practical step we consider appropriate. Not an obligation following from the Regulation.

For every application, record three answers in your AI register with a date and the name of the assessor: does it operate with some degree of autonomy, does it infer from input how to generate output, and what is that output. When the outcome is negative, keep the reasoning, because that is the document with which you later explain why the system is out of scope.
