UnverifiedAt 4-bit precision and above, quantization has limited impact on output quality for most application scenarios.76% similarVerified4-bit quantization (such as Q4_K_M) can typically compress the memory footprint of a 3B model from approximately 6GB to approximately 2GB, with a precision loss of less than 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
