VerifiedThe size of the KV cache grows linearly with context length; the KV cache for Qwen 2.5 32B at a 64K context may consume several additional gigabytes of memory.70% 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.67% similarUnverifiedIt is recommended to keep KV cache precision at 8-bit or 16-bit when VRAM permits, especially in long-context or precise tool-calling scenarios.63% similarUnverifiedFor the LLaMA-2 70B model, when processing a context of 4096 tokens, the KV Cache requires approximately 20 GB of system memory at FP16 precision.63% similarUnverifiedFor a 27B-class model, even if the weights are compressed to around 5GB, the KV cache under long contexts can still occupy several GB, becoming the real bottleneck for phone memory.61% similar
