Provider and deployer
Who supplies an AI system and who uses it, with very different duties.
What is Provider and deployer?
The EU AI Act mainly distinguishes two roles. Providers develop an AI system or have it developed and place it on the market under their own name. Deployers use a system under their own responsibility. Different duties attach to each role, from conformity assessment to oversight in operation.
In practice the assignment is the most common point of dispute. Anyone who substantially modifies a purchased system, offers it under their own name or changes its purpose can become a provider themselves. The role should therefore be documented and justified per system, not silently assumed.
