Q8_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.

UnverifiedQ6_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79% similarUnverifiedCompared to Q4 quantization, Q8 quantization retains higher precision closer to the original model quality, but consumes more VRAM.78% similarUnverifiedRecommended quantization gradient choices: Q8 is nearly lossless but has the largest footprint, Q6/Q5 are the sweet spot between quality and size, Q4_K_M is the default download version for most users, and the Q2/IQ series is suitable for use when the model barely fits.78% similarVerifiedGGUF量化格式（如Q4_K_M）通过将权重精度从32位浮点压缩到4位整数，通常只带来约1-5%的性能损失75% similar
