What do you actually have to do?
Maintain model technical documentation and provide information to downstream providers integrating the model. Free and open-source models with public weights are exempt from these two duties unless the model has systemic risk (Art. 53(2)).
Statutory basis: Art. 53(1)(a)-(b) — https://artificialintelligenceact.eu/article/53/
When does it apply?
- 2027-08-02 — legacy models placed before 2 August 2025: comply by 2 August 2027 (Art. 111(3))
- 2025-08-02 — in force since 2 August 2025
Does ISO 42001 or NIST AI RMF cover this duty?
Requirement-level mappings from Shieldra's crosswalk pack (v2026.07.30). Partial mappings contribute evidence but deliberately do not count as coverage.
| Mapped requirement | Strength | Why (and what’s missing) |
|---|
| ISO/IEC 42001 A.6 | Partial | A.6 life-cycle technical-documentation practice supplies the habit, but Annexes XI/XII prescribe specific model documentation content the standard does not. |
| ISO/IEC 42001 A.8 | Partial | Providing system information to downstream integrators is an A.8 interested-party information duty; Art. 53 fixes the exact content and recipients. |
| NIST AI RMF MAP-2.1 | Partial | Documenting the model's tasks and methods supplies part of the Annex XI model description. |
| NIST AI RMF MAP-2.2 | Partial | Documented knowledge limits and output-use guidance overlap with the downstream-provider information Art. 53 requires. |
| NIST AI RMF MEASURE-2.1 | Partial | Documented test sets, metrics, and evaluation tooling feed the evaluation-results sections of the required model documentation. |
