**TLDR:** A system approach that reduces latency and cost by reusing prior answers for semantically identical or similar queries.

<p>Semantic caching aims not only to reuse answers for exact query matches, but also for semantically equivalent ones. This is highly valuable for cost optimization in high-volume LLM and RAG services. However, incorrect similarity matches can degrade user experience, so safe threshold design is essential.</p>
