The open-source tool galahad-kv saves the KV states of each approximately 16,000-token chunk to an encrypted local NVMe disk, then reloads them byte-accurately, completely skipping recomputation.

VerifiedThe disk caching mechanism persists already-computed KV Cache to storage media; when a subsequent request's prefix hits the cache, it can be reused directly, skipping redundant forward propagation.65% similarUnverifiedKV Cache stores the Key and Value matrices of all previous tokens during the Decode phase, grows with conversation turns and context window size, and can occupy anywhere from a few GB to tens of GB of memory in long-text scenarios65% similarUnverifiedThe deployment uses a llama.cpp server with 4-bit KV cache, context length set to 100,000, 32 layers offloaded to system memory, and lazy mode enabled to force the Ngram table to be read from SSD.65% similarUnverified自回归解码阶段每生成一个新token都需读取完整KV Cache，使解码阶段几乎总是受限于内存带宽而非计算能力65% similarVerifiedTaking the LLaMA-2 70B model as an example, a sequence of 2048 tokens requires approximately 4 GB of VRAM for the KV cache alone.64% similar
