HotKV, a semantic caching system, has demonstrated a significant reduction in LLM operational costs by serving repeated and similar customer support queries from memory. In tests using Anthropic's Claude models, HotKV decreased token usage and API expenses by approximately 70%. While exact matches were perfectly served, semantic matching at a default 0.81 similarity threshold resulted in a slight decrease in answer relevance compared to direct model calls, though this gap was mitigated at higher similarity thresholds.
