EU AI Act · Art. 53(1)(a)-(b)
GPAI model documentation and downstream information
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)).
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)).

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. |
