Proprietary Risk Framework Assessment: RAG Over Fine-tuning

RAG POC ~$40K vs ~$300K fine-tuning path: same validated quality band, overnight framework updates.

The Problem

A financial services firm was evaluating an ~$300K fine-tuning project to encode proprietary risk frameworks across multiple scoring dimensions.

The Solution

A short RAG POC over existing risk documentation that matched the proposed fine-tuned quality at a fraction of the cost, with daily re-index updates instead of retraining.

Business Impact

Budget that would have gone to fine-tuning funded a second use case. Risk frameworks update when policy changes: same week, not next quarter.
