UnverifiedIn speculative decoding scenarios, the Q3 quantized version is actually slower than the Q4 quantized version.78% 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% similarUnverifiedCompared to Q4 quantization, Q8 quantization retains higher precision closer to the original model quality, but consumes more VRAM.73% similarUnverifiedQ4_K_M has a perplexity approximately 0.1–0.3 lower than pure Q4.73% similarUnverifiedCommunity practice recommends prioritizing Q5 or Q6 quantization if capacity allows; Q4_K_M is the minimum acceptable baseline, and Q3 or below causes significant quality degradation and is not recommended for production use.71% similar
