Traditional model quantization takes the path of reducing the numerical precision of weights, evolving from FP16 to INT8 and then to 4-bit, 2-bit, and even 1-bit.

UnverifiedThe performance gap between a carefully quantized 4-bit model and the original FP16 model is typically within 1–3 percentage points.80% similarUnverifiedThe core principle of quantization is to convert model parameters from high-precision floating-point representations (such as FP32's 32-bit floating point) to low-precision representations (such as INT8's 8-bit integer or INT4's 4-bit integer).78% similarUnverified对于7B至13B参数级别的模型，4-bit量化后的输出质量与全精度版本差异很小74% similarVerifiedThe larger the number of model parameters, the greater the robustness to quantization, allowing 70B-level models to maintain performance close to FP16 after 4-bit quantization.74% similarUnverifiedINT4量化将原本由65536个不同值（FP16）表示的权重压缩到仅16个离散级别72% similar
