UnverifiedQ4_K_M (4-bit quantization, K-means optimized) is currently the best overall choice, with a precision loss of approximately 2–5%, and is the most widely used quantization format in the community.76% similarUnverifiedThe Q4_K_M quantization scheme averages approximately 4.8 bits per weight, while the Q8_0 quantization scheme uses 8 bits per weight.74% similarUnverifiedK-Quant是llama.cpp生态中的混合精度量化方案，根据每层权重敏感度分配不同量化bit数，可在相同平均bit数下将精度损失降低40-60%73% similarUnverifiedCommunity rule of thumb holds that Q4_K_M (4-bit medium-precision quantization) offers the best balance between performance and file size in most scenarios.73% similar
