UnverifiedIn speculative decoding scenarios, the Q3 quantized version is actually slower than the Q4 quantized version.77% 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76% similarUnverifiedIt is recommended to start with the Q4 quantized version before deciding, based on actual performance, whether to switch to a higher-precision version.75% 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.73% similar
