OUT-12Model version pinning

Foundation models in use are pinned to specific versions where the provider supports pinning. Provider-pushed model updates are tested before release to production traffic.

The agent operates against pinned model versions; upstream model changes go through change management. Provider-pushed model updates are tested against the standing evaluation set (SPC-07) and the behavior baseline (SPC-06) before release to production traffic. Material deltas are treated as material change under GOV-05. This control prevents silent model updates from changing agent behavior without oversight.

Table OUT-12.1 · 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.

Model versions are pinned for all production agents where the provider supports pinning; the most recent provider-pushed update was tested before production release; material deltas triggered change management.

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

    Model versions are pinned for all production agents where the provider supports pinning.

  2. E.2

    The most recent provider-pushed update was tested before production release.

  3. E.3

    Material deltas triggered change management.

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.
