AI Model Provenance & Openness

AI Model Provenance & Openness

Why important?

The provenance and openness of models determine the independence and auditability of the AI layer.

How measured?

Scale 0–5 + N/A:
  • 0 = Model origin not transparent; only proprietary non-EU models without a switching option.
  • 1 = Proprietary models, origin documented, no model switching and no openness.
  • 2 = Choice of several models; some open weights; limited portability.
  • 3 = Open weights or EU/known model origin; model switching possible without lock-in.
  • 4 = Predominantly open or EU-sovereign models; good portability of the AI layer.
  • 5 = Full provenance transparency; open-weights or EU-sovereign models; free portability + verifiable evidence.
  • N/A = no reliable evidence

Validation questions (RFP)

  • Where do the model and its weights come from, in which version, under which licence and with which integrity evidence (hashes, signatures), and is this disclosed per model? Can the model be switched or self-hosted without lock-in? Which AI-specific assessments (e.g. BSI AIC4, ISO/IEC 42001) exist, and with what scope?
