Who it applies to
GPAI model provider in scope (Art. 2, Art. 3(63)) — all of these:
- Project involves providing a general-purpose AI model (GPAI)
- GPAI assessed Union model scope: YES
- GPAI assessed Article 51 classification: YES
What engineering work it implies
- Annex IV Technical Documentation as CodeCovers part of it

Sample acceptance criteria Landfall generates for this obligation:
- Version Annex XI Section 2 evaluation, testing/adaptation and architecture records alongside Section 1 and preserve authority-request deadlines
- Minimise personal data and document an actor-specific retention basis or justified organisational policy
- The Annex XI Section 2 file is assessed independently of a high-risk-system Annex IV template
- Internal change and response targets are identified as organisational choices rather than universal statutory deadlines
- Provide attributable evidence for the cited provision and model version, with source version, review date and the applicable transition assessment
Evidence an auditor expects
- Policy documentDocument review
Additional systemic-risk GPAI documentation (Article 53(1)(a), Annex XI Section 2)
Include evaluation strategies/results, criteria, metrics and limitation-identification methodology.
