UnverifiedChoosing 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% similarUnverifiedKimi K2在FP16精度下仅模型权重就需要数百GB显存，INT4量化可将显存需求压缩至约四分之一76% similarVerifiedQuantized KV caches (such as storing KV vectors in FP8 or INT4) can compress the cache size to 1/2 or even 1/4 of the original.76% similarUnverifiedQuantization technology compresses 32-bit or 16-bit floating-point weights into 4-bit or 8-bit integer representations, trading a small amount of precision for improvements in memory usage and speed.75% similar
