OUT-05Model provider inventory

A model provider inventory is maintained, identifying which foundation models are in use for which agents, under which contractual terms, and with what data-use commitments.

The organization maintains a current inventory of all model providers used across its agent estate. For each provider-agent relationship, the inventory records the model version, contractual terms, data-use commitments, and any restrictions on use. This inventory is the foundation for supply-chain risk management and is referenced by OUT-09 and OUT-12.

Table OUT-05.1 · Maturity criteria · v.1.3

L1 to L5 · the lowest level in scope caps the agent
L1Ad hoc

Controls exist informally; documentation is incomplete; no consistent review.

L2Documented

Controls are written down; ownership is assigned; review cadence is defined.

L3Operated

Controls are followed in practice; evidence is collected; deviations are tracked.

Inventory exists and covers all provider-agent relationships; entries are current within the documented cadence; contractual terms and data-use commitments are documented; inventory is referenced in vendor management reviews.

L4Measured

Control effectiveness is measured against documented thresholds; trends are reported.

L5Continuously Improved

Controls evolve based on incident learning; maturity gains are evidenced over time.

The v1.3 edition publishes a control-specific criterion at L3 (Operated). The other levels apply the general ladder to this control; see the maturity ladder.

Evidence an assessor asks for

  1. E.1

    Inventory exists and covers all provider-agent relationships.

  2. E.2

    Entries are current within the documented cadence.

  3. E.3

    Contractual terms and data-use commitments are documented.

  4. E.4

    Inventory is referenced in vendor management reviews.

Mappings are directional: meeting this control evidences but does not by itself satisfy the external requirement. A middle dot means no control-level reference is published at this edition; see the crosswalk.
