Semantic Caching(SCA)
Cache LLM or agent responses keyed by embedding similarity rather than exact string match, so semantically equivalent queries reuse a stored answer. A similarity threshold decides a hit, a freshness TTL bounds staleness, and an invalidation policy evicts entries when source data changes. This cuts cost and latency on high-volume traffic and is distinct from prompt-prefix or KV caching.
