The core caching challenge of hybrid architectures is that attention layers need to save a complete KV Cache for prefix reuse, while the hidden state of a Mamba layer is a lossy compression of the sequence and cannot precisely restore historical information at arbitrary positions.

UnverifiedKV 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.68% similarUnverifiedKV cache reuses the Key and Value matrices of historical tokens during the inference phase, avoiding repeated attention computation on already-generated sequences.68% similarUnverifiedIn 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.66% similarUnverifiedPrompt缓存必须从前缀开始严格匹配，一旦中间某个token变化，其后所有token的注意力计算都会改变，已缓存的KV对随之失效66% similarUnverifiedKV caching reduces the attention computation complexity from quadratic to linear growth by caching the Key and Value vectors of historical tokens.62% similar
