Production in Retrieval-Augmented Generation

Lessons in this section

1. RAG Evaluation

   Measuring RAG with numbers: Precision@K, Recall@K, hit rate and MRR; faithfulness, context relevance and citation accuracy; gold chunk matching, test suites, the RAG Triad and LLM-as-judge.

2. Production Operations

   Running RAG in production: full traces, bottlenecks and per-stage latency, re-indexing, eviction and versioning, monitoring and low-similarity alerts, feedback loops, and prompt and response caching.

3. RAG Reference

   A quick-reference page for RAG: the pipeline at a glance, RAG vs alternatives, metric and scoring formulas, starting settings, a grounded prompt template, troubleshooting, security checklist and glossary.
