Input data

The data entering the system or acquired by it, on the basis of which it produces its output. This is the data definition that touches the deployer, not just the provider.

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(33) defines input data as data provided to or directly acquired by an AI system on the basis of which the system produces an output.

Our interpretation

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

This is where responsibility moves to your side of the table. Article 26(4) requires the deployer to ensure that input data are relevant and sufficiently representative in view of the intended purpose, to the extent it exercises control over them. The most persistent misconception is that data quality is the supplier's problem. Prompts, uploaded CVs, sensor readings, customer files and connected source systems are all input data, and an excellently built system produces unusable outcomes when you feed it outdated or skewed data. Note the second half of the definition as well: data the system acquires itself, for instance through a camera or an API, are equally input data and therefore fall within your duty of care.

Recommended step

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

Record per AI system which input data are used, which source systems they come from, who owns their quality and representativeness, how often that is checked, and how long the input is retained in the logs. Explicitly name the input sources you do not control, since that marks the boundary of your duty of care.
