# Deployer

Under the EU AI Act, whoever uses an AI system under its own authority, other than in a purely personal, non-professional activity [1]. For high-risk systems it follows the instructions for use, staffs oversight, monitors, keeps logs, informs affected people and, in listed cases, performs the FRIA. The label names a task, not a kind of organisation.

## Commonly confused

- **Provider** vs **Deployer**: Develops the system and places it on the market under its own name, against uses it under its own authority Different duties and different evidence; a substantial modification can turn a deployer into the provider
