RAG guide

RAG compression evaluation

Adding compression to a RAG pipeline changes the context the LLM sees. Proper evaluation ensures that quality is maintained while costs are reduced.

Evaluation framework

  1. Answer accuracy — Does the LLM still answer correctly with compressed context?
  2. Faithfulness — Does the answer hallucinate or contradict the compressed context?
  3. Relevance — Is the compressed context sufficient for the answer?
  4. Compression efficiency — What percentage of tokens was removed?

Frequently asked questions

What evaluation dataset should I use?

Use 100-500 real queries from your production logs with human-verified ground truth answers.

How much quality regression is acceptable?

Zero regression is ideal. If you see regression, reduce the compression budget.
