Contextual Cache Management
Also known as: Prompt Caching, KV Cache Reuse
An inference engine optimization that saves and reuses KV cache states for shared prompt prefixes across multiple API calls.
What Contextual Cache Management is
Contextual Cache Management reduces latency by up to 80% and lowers API costs for long-system-prompt workflows.
How it works
Stores computed KV cache tensors in GPU/host memory, indexed by cryptographic hashes of prompt prefixes.
Why it matters
Core feature in enterprise LLM APIs like Anthropic, OpenAI, and vLLM deployments.
Common uses
- →Cost reduction in long-context APIs
- →Fast multi-turn chat applications
- →Repeated document RAG queries
