The skills, knowledge and understanding that let people use, operate and assess AI systems with awareness of their opportunities, risks and possible harms.

Any organization that provides or deploys AI in the EU, including staff use of general-purpose chat tools, has had to take AI literacy measures since February 2025, and trained staff are also the first control against misuse and data leaks.

A 60-person agency maps which roles use which AI tools, runs a 90-minute session on approved tools, data rules and output checks, adds a module for developers, and keeps attendance lists and training materials as internal records.

Article 4 does not prescribe a curriculum, certificate or test, so each organization must judge what fits each role and risk level. One generic course rarely covers deployers of high-risk systems, whose staff also need human oversight training.

Article 4 of the EU AI Act requires providers and deployers to take measures supporting the AI literacy of their staff and others operating AI systems on their behalf, taking into account technical knowledge, experience, training and context of use. It has applied since 2 February 2025, and national market surveillance authorities supervise it. The Digital Omnibus amendments added support duties for the Commission and Member States. Measures can be recorded within an AI Management System.
