Article 55 — Obligations of providers of general-purpose AI models with systemic risk

▼ Primary text, verbatim. Our annotations appear below, visibly separated.

1. In addition to the obligations listed in Articles 53 and 54, providers of general-purpose AI models with systemic risk shall:

(a) perform model evaluation in accordance with standardised protocols and tools reflecting the state of the art, including conducting and documenting adversarial testing of the model with a view to identifying and mitigating systemic risks;

(b) assess and mitigate possible systemic risks at Union level, including their sources, that may stem from the development, the placing on the market, or the use of general-purpose AI models with systemic risk;

(c) keep track of, document, and report, without undue delay, to the AI Office and, as appropriate, to national competent authorities, relevant information about serious incidents and possible corrective measures to address them;

(d) ensure an adequate level of cybersecurity protection for the general-purpose AI model with systemic risk and the physical infrastructure of the model.

2. Providers of general-purpose AI models with systemic risk may rely on codes of practice within the meaning of Article 56 to demonstrate compliance with the obligations set out in paragraph 1 of this Article, until a harmonised standard is published. Compliance with European harmonised standards grants providers the presumption of conformity to the extent that those standards cover those obligations. Providers of general-purpose AI models with systemic risks who do not adhere to an approved code of practice or do not comply with a European harmonised standard shall demonstrate alternative adequate means of compliance for assessment by the Commission.

3. Any information or documentation obtained pursuant to this Article, including trade secrets, shall be treated in accordance with the confidentiality obligations set out in Article 78.

What this means for you

In your terms · Systemic-risk model obligations

Adversarial testing of the model is conducted and documented; the runs and their records are engineering work.

  • Documented adversarial test runs for the model

An open model, fine-tuned and sold inside your product

Illustrative Reading still settling

You took an open-weight model, fine-tuned it on your own data, and it now powers a paid feature in the product you sell.

Your role
Provider
Where it lands
Not classified In force 2 Aug 2025
Decided by
Chapter V, as the provider of the modified model, and separately whatever Article 6 says about the system you built on it.

What you have to be able to produce

  • Downstream information pack
  • Model documentation
  • Onboarding notes for AI-touching roles
  • Provider-status assessment for fine-tunes
  • Public training-content summary
  • Team enablement plan for people operating AI systems
  • Written mandate for the model's authorised representative

What would change the answer

  • The Article 53(2) exception covers models released under a free and open-source licence with public parameters, architecture and usage information, and it never covers a model with systemic risk.
  • Recital 103 reads components provided against a price or otherwise monetised as outside the free and open-source exceptions. A recital is interpretive context, not operative law, and it is the weakest link in this row.
  • Crossing the Article 51 systemic-risk threshold adds the Article 55 duties and removes the exception entirely.
