VerifiedMLA 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.76% similarUnverifiedChoosing Q4_0 for KV cache quantization can compress the cache size to approximately one-quarter of FP16, with far less impact on output quality than model weight quantization.76% similarUnverifiedMLA theoretically reduces the GPU memory footprint of KV Cache to 5% to 13% of standard MHA by compressing KV matrices into low-dimensional latent vector caches.75% similarUnverifiedReducing the KV cache from FP16 to INT8 saves 50% of VRAM, and reducing it to INT4 saves 75%.75% similarUnverifiedMLA（Multi-head Latent Attention）通过低秩压缩将 KV 缓存的显存占用降低至传统 MHA 的约 1/874% similar
