A smaller classic model: Which model choice best fits these constraints?

AIGP Understanding How to Govern AI Deployment and Use Hard

A smaller classic model best satisfies explainability, on-premise hosting, and limited compute for an auditable regulated decision.

The question

A regulated lender needs a model for an auditable, explainable credit decision. It must run on-premise on modest hardware, and every decision must be defensible to auditors. Which model choice best fits these constraints?

  1. A large proprietary generative model accessed via API, which offers state-of-the-art fluency and offloads infrastructure and maintenance burdens onto the vendor.
    Plausible for capability, but an external API violates the on-premise constraint and generative opacity undermines auditability.
  2. A large open-source generative model fine-tuned in-house, giving full weight access and customization while still delivering broad general-purpose language capabilities.
    Plausible because it is on-premise, but its size strains modest hardware and its probabilistic reasoning is hard to explain to auditors.
  3. A multimodal generative model, which handles text and images together and future-proofs the deployment against later expansion of the credit use case.
    Wrong because multimodal capability is unnecessary here and adds cost and opacity that conflict with the explainability and compute constraints.
  4. A smaller classic (non-generative) model, which is typically more interpretable, cheaper to run on-premise, and better suited to a regulated, auditable decision.
    Correct because a compact classic model aligns with the explainability, on-premise, and compute constraints the scenario imposes.
The trap
Assuming a larger or generative model is always the stronger choice, ignoring explainability and compute constraints.
