Downstream Provider
Under the EU AI Act: a provider whose system integrates a general-purpose AI model made by someone else.
Downstream providers build products on top of another party’s GPAI model. The Act obliges the upstream model provider to supply the technical information downstream providers need to meet their own obligations. It is the mechanism that makes the value chain legible instead of a black box.
In practice: Building and selling a legal assistant on top of someone else’s API.
