UnverifiedVector quantization always faces the fundamental challenge of a precision-efficiency trade-off: the higher the compression ratio, the greater the quantization error and the lower the recall rate.78% similarUnverified极端量化技术存在压缩率与能力保留之间难以回避的根本权衡72% similarUnverified量化的核心挑战在于处理权重分布中的异常值,LLM权重中少量极大值会显著放大量化误差71% similarUnverifiedIt is widely recognized in the industry that quantization below 2-bit leads to significant capability degradation on high-precision tasks such as complex multi-step reasoning and mathematical computation.68% similarUnverifiedQuantization is not lossless compression; the lower the precision, the greater the degradation in model inference quality (perplexity, logical reasoning capability), and 4-bit quantization is considered a good balance point between quality and size.67% similar
