Cache eviction policies include LRU, LFU, and weighted schemes that consider prefix length or recomputation cost; frequent cache eviction reduces the effectiveness of cache-aware routing.

UnverifiedAdvanced caching strategies require additional metadata tracking, scoring computation, and maintenance costs, and after accounting for these overheads, their net gain relative to LRU may shrink substantially.78% similarUnverifiedLRU (Least Recently Used) is a cache eviction algorithm whose core idea is to evict the data that has not been accessed for the longest time.75% similarUnverifiedThe cached input mechanism skips repeated inference computation by reusing the KV cache for identical prefix content, with cache-hit tokens billed at a lower price.74% similarVerifiedThe semantic caching mechanism vectorizes and stores historical responses to similar requests, and when semantic similarity exceeds a threshold, it directly returns cached results to reduce upstream API call frequency and costs71% similarUnverifiedThe classic LRU algorithm is prone to cache pollution in one-time large-batch read scenarios such as full-table scans, evicting hot data from the cache.69% similar
