AI literacy: what Article 4 requires now that the Omnibus rewrote it

Article 4 required measures to ensure a sufficient level of literacy. The Digital Omnibus replaced it: now the measures must support its development, and the article itself rules out requiring a specific level from anyone.

AI literacy is the first obligation under the AI Act that reaches any company using AI, whatever the risk level of its systems. It has been in force since February 2025 and doesn't depend on having anything classified as high-risk.

It's also the worst-described one, because the article that establishes it no longer says what it used to say.

Article 4 asks for proportionate measures, not a specific level of AI literacy of any individual. The loop is the method; the central record is the evidence it leaves.

The figure draws Article 4 as an obligation of means: it asks for proportionate measures, not a specific level of AI literacy of any individual. It is a four-step loop — identify who operates AI and with which systems; train in line with the context of use and each person's profile; document which measures were taken, for whom and when; and review when the systems or the people change — around a central record, the evidence of the AI literacy measures. Article 4 does not require documenting: the record is evidence of the method.

What it used to say, and what it says now

The original text of Article 4 required providers and deployers to “take measures to ensure, to their best extent, a sufficient level of AI literacy of their staff and other persons dealing with the operation and use of AI systems on their behalf”.

Regulation (EU) 2026/1744 — the Digital Omnibus — replaced the entire article. The wording in force reads:

“Providers and deployers of AI systems shall take measures to support the development of AI literacy of their staff and other persons dealing with the operation and use of AI systems on their behalf, taking into account their technical knowledge, experience, education and training and the context the AI systems are to be used in, and considering the persons or groups of persons on whom the AI systems are to be used. This obligation does not require providers or deployers to guarantee any specific level of AI literacy of any individual.”

That last sentence wasn't there before, and it's unusual: the article itself expressly denies that this is an obligation of result. There's no need to interpret the change — the legislator wrote its scope into the text itself.

What actually changes, and what doesn't

The type of duty changes. From adopting measures to ensure a level to adopting measures to support development. The first is measured by the outcome in people; the second, by what the organisation does.

The subject doesn't change. It still reaches providers and deployers. If your company uses AI in its operations, it applies to you exactly as before.

The adequacy criterion doesn't change. The article still provides that the measures are taken “taking into account their technical knowledge, experience, education and training and the context the AI systems are to be used in” and the persons on whom the systems are used. It isn't generic training: it's proportionate to who uses what, and on whom.

And the obligation doesn't disappear. This is worth stating plainly, because the lazy reading of the change is "there's nothing left to do." The article still says “shall take measures”. What it no longer requires is proving a level reached by each person.

Why it was relaxed

The Regulation itself explains why: experience shared by stakeholders reveals that a solution imposing “stringent obligations to ensure a sufficient level” of AI literacy would not be suitable for all types of providers and deployers, and that imposing them creates an additional compliance burden particularly for smaller enterprises — while AI literacy should be a strategic priority regardless of regulatory obligations.

In other words: it was relaxed because the previous formula asked a twenty-person company for something it could neither measure nor had any reason to measure. Not because the matter stopped mattering.

What this means in practice

The difference between the two wordings isn't cosmetic, and it shows in what you'd be asked to produce.

With the old formula, the natural question was “what level does your staff have?” — a question almost no SME could answer without setting up assessments.

With the one in force, the question is what measures the organisation adopted, for whom, and why those ones. That can be answered, and it's answered with a record: what was done, when, who took part, and what criterion was followed to decide those measures were the right fit for the context.

And that's exactly the kind of thing that separates ticking a box from having evidence: a certificate of attendance at a generic course proves there was a course. A record stating which systems each team uses, which measure was taken for each profile and on what criterion, proves there was a decision.

The error this change produces

There are two ways to describe Article 4 wrong today, and both are in circulation.

"It requires you to guarantee your workforce's training." It was almost true under the previous text, and today the article's own closing sentence contradicts it. It's the same kind of error as the Annex III date or the marking grace period: a statement that was accurate and stopped being so without the sentence itself changing.

"It no longer requires anything." That's the opposite error, and it comes from reading only the last sentence. The article still imposes the duty to adopt measures, on the same subjects, with the same proportionality criterion.

Between the two sits what the text actually says: an obligation of means — alive, enforceable, and adaptable to the size of the organisation.

What's worth having

Three things, and none of them is a corporate training plan.

Who uses what. You can't adopt measures proportionate to the context without knowing which systems each team uses. It's the same inventory that serves every other purpose.

Which measure was taken for each profile, and why that one. The "why" is what turns a list of courses into a defensible decision.

When it was reviewed. Because staff change, systems change and — as this very article shows — the rule changes too. A measure adopted two years ago for tools that are no longer in use proves nothing.

None of the three requires a training platform. They require the answer to be written down, dated, and kept somewhere it will still be when someone asks. If the company has an AI use policy, that is the natural place for it: what its training clause must say, alongside the other seven.

Frequently asked questions

Does Article 4 require staff to reach a specific level of AI literacy?

No. In the wording in force, that of Regulation (EU) 2026/1744, the obligation does not require providers or deployers to reach any specific level of AI literacy for any individual.

Is Article 4 still binding?

Yes. Providers and deployers shall take measures to support the development of their staff's AI literacy, taking into account their knowledge, experience, education and training and the context of use. It has applied since 2 February 2025.

What is worth being able to show?

Which measures were adopted, for whom and on what criterion, with a date: for example, which systems each team uses and which measure was taken for each profile. The Regulation does not set a format.
