UnverifiedUnder the same host memory with a concurrency setting of 32, traditional KV offloading can only sustain 5–6 requests, whereas Hybrid HiSparse can simultaneously maintain 19–25 requests, improving effective concurrency by approximately 3 to 4 times75% similarUnverifiedReducing the KV cache from FP16 to INT8 saves 50% of VRAM, and reducing it to INT4 saves 75%.70% similarUnverifiedvLLM v0.28.0's tiered KV offloading adds a disk tier and supports out-of-tree secondary cache layers.68% similarUnverifiedKV cache runtime provides a low-cost, fine-grained, real-time intervention capability that fills the gap between model fine-tuning and external scaffolding.68% similarVerifiedMLA compresses the KV Cache into low-dimensional latent vectors via low-rank decomposition, with d_latent approximately 1/8 of d_model, reducing KV Cache VRAM usage to 5%–13% of traditional multi-head attention.68% similar
