Caching is the highest-impact performance optimization for production RAG. Here are the layers and what actually hits.
RAG costs can balloon fast. Here are the costs that matter and the levers for controlling them at scale.
Production RAG has strict latency budgets. Here's where time goes and how to cut it without killing quality.
Without observability, RAG bugs are invisible. Here's what to log, what to track, and how to debug production RAG issues.
RAG systems expand the attack surface. Prompt injection, data leakage, access control bypass. Here are the threats and the mitigations.
