VerifiedIn GGUF quantization naming, Q4_K_M denotes a 4-bit quantization, Medium-precision variant using the K-Quant grouped quantization method77% similarVerifiedQ4_K_M中的K代表k-quants方案，M代表中等质量级别，是llama.cpp引入的混合量化策略77% similarUnverifiedLetter suffixes in quantized version names represent different quantization strategies; the K series uses mixed precision to retain higher precision for critical layers and generally outperforms earlier uniform quantization schemes at the same size.75% similarUnverifiedQ6_K 使用 6-bit 量化并结合 K-quants 分组技术，相比 Q4 量化损失更小，相比 Q8 量化体积更小74% similarUnverifiedQ8_0 is 8-bit block quantization with high precision but limited compression; Q4_K_M balances size and quality through mixed precision at the 4-bit level and is one of the commonly used default tiers for local deployment.71% similar
