What does research say about: Semantic routing prevents unnecessary LLM calls?

Semantic caching intercepts 25-40% of production queries that are paraphrases of previously answered questions, saving $0.015 per cached hit. (Source: Zilliz, 'GPTCache: An Open-Source Semantic Cache for LLM Applications', 2023). Without deterministic prompt schemas, exact-match caching is impossible — every slight rewording triggers a fresh API call at full cost.
