  • Measure retrieval quality, faithfulness, and reasoning consistency.

  • Prevent regression via automated eval gates.

Tooling

  • RAGAS: RAG faithfulness and answer relevance.

  • TruLens or DeepEval: model evaluation and rubric scoring.

  • Promptfoo: prompt regression and scenario testing.

Evaluation Flow

  1. Run batch evaluation against golden datasets.

  2. Gate deployments on thresholds.

  3. Log metrics to observability stack for trend analysis.
