What the law now asks
You are a deployer as soon as you use an AI system under your own authority, for example a tool that sorts CVs or a language model that writes job ads [1]. As a deployer you take measures that support the development of AI literacy among your staff and others who work with AI systems on your behalf [2]. The duty does not mean that you must ensure a particular level [3].
Since when, and what changed
Article 4 is in Chapter I of the AI Act, and that chapter has applied since 2 February 2025 [4]. The original text asked to ensure, to their best extent, a sufficient level of AI literacy [5]. Regulation (EU) 2026/1744 replaced that text; it was published on 24 July 2026 [6] and entered into force on the third day after that [7], that is on 27 July 2026.
What that means for HR
Tailor the measures to who does what: a recruiter who reads candidates' AI scores needs different knowledge from an employee who has a chatbot write texts. The law names as benchmarks technical knowledge, experience, education and training, the context of use and the persons on whom the systems are used, such as applicants and employees [2]. The Commission and the Member States support SMEs in this, and the Commission publishes practical examples [8]. Record which measures you take, so that you can show them later.
