## AI overview

The article explains semantic caching for repeated questions in production LLM applications, including Redis LangCache's embedding-based similarity search, filters, expiration, eviction, and monitoring. It also explains how mixture-of-experts inference routes tokens to selected experts and why active parameters do not represent the full deployment memory footprint.
