Commonly confused

  • Model card versus System card

    Model card
    Structured, versioned documentation of a model (provenance, intended use, capabilities, evaluations and known failure modes) maintained as code.
    System card
    Documentation of a deployed AI system as a whole (models, prompts, retrieval, tools, guardrails and oversight), where a model card documents one model.

    The differenceOne model's documentation, against the deployed system's: models, prompts, retrieval, tools, guardrails and oversight.

    Why it mattersDeployers and authorities need the system view; a model card alone misses the controls around the model.
