KV cache hits (prefix caching) are not zero-cost; storage, bandwidth and garbage collection all incur costs, they are just amortized.

UnverifiedZeroing KV Cache pages comes at a speed cost, because the whole point of caching is to avoid recomputation, so there is a structural trade-off between security and performance.78% similarUnverifiedKV cache runtime provides a low-cost, fine-grained, real-time intervention capability that fills the gap between model fine-tuning and external scaffolding.77% similarUnverifiedMethods for compressing the KV Cache include quantization, low-rank approximation, and evicting old tokens by importance; their direct effect is to increase the number of tokens (capacity) that a unit of GPU memory can hold, rather than to save compute or transfer.75% similarUnverifiedIn KV caching, cache writes are usually about 25% more expensive than ordinary input tokens, but cache reads are about 90% cheaper.75% similarUnverifiedWhen implementing a KV cache, one should compare the cached and uncached versions token by token on greedy output over long sequences (e.g., more than 200 tokens) rather than only performing single-step validation, in order to effectively verify cache correctness.73% similar
