An incorrect KV cache ordering can pass a single-token test, because when only one token is generated the cache has only one history entry and any ordering degenerates to the same result; the output deviation is only exposed once the sequence grows longer and the cache has multiple entries.

VerifiedIn the KV Cache mechanism, reusing cached KV values is a cache hit, while context changes that invalidate the cache and require recomputation are a cache miss.76% similarUnverifiedKV Cache reduces inference computational complexity from O(n²) to O(n) by caching and reusing the Key and Value vectors of historical tokens; if the cache is incorrectly truncated, overwritten, or subject to cross-session interference, it causes context confusion and triggers loops.69% 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.69% similarUnverifiedMisaligned tokenization logic between the sampling side and the scoring side causes the same text to be split into different token sequences, resulting in probability inconsistencies.68% similarUnverifiedEvicting the KV entries of low-value tokens has become a key means of reducing the cost of long-context inference.67% similar
