UnverifiedAt 4-bit precision and above, quantization has limited impact on output quality for most application scenarios.76% similarVerified4-bit量化（如Q4_K_M）通常可将3B模型内存占用从约6GB压缩至约2GB，精度损失低于2-3%73% similarVerifiedStacking techniques such as K-quant, GPTQ, and AWQ can smoothly extend quantization to 4-bit, but performance catastrophically collapses when pushed to 2-bit or 1-bit.72% similarUnverified4-bit quantization can reduce model size by approximately 75%.72% similar
