Verified4-bit量化理论上可将模型体积缩小8倍（相比32位存储）79% similarUnverifiedWhen a large portion of the model is offloaded to the CPU, any quantization bit-width that cannot be divided evenly by 2 incurs a speed penalty, making 3-bit actually slower than 4-bit.78% similarUnverifieddecode阶段的生成速度近似等于内存带宽÷模型大小，例如在内存带宽273GB/s的M4 Pro上运行4GB的Q4量化7B模型理论最大生成速度约68 tokens/s78% similarUnverifiedQuantprobe claims to enable a machine with only 6GB of VRAM and 16GB of RAM to run 30B-class models at 22 tokens/s.78% similar
