Quantization
A technique that compresses neural network weights from high-precision floating-point representations into low-bit integer representations. It reduces memory footprint and computational load, facilitating local deployment.
Core Facts
Timeline (last 90 days)
Quantization techniques can compress trained neural network weights from FP16/FP32 to INT8/INT4, significantly reducing model size, lowering memory usage, and improving inference speed, at the cost of possible accuracy loss.
Quantization technology enables ordinary consumer-grade graphics cards (such as the RTX 3090 and 4090) to run models with billions of parameters.
Although quantization technology can reduce hardware requirements, it introduces a certain degree of performance degradation.
With advances in quantization technology and improvements in consumer-grade hardware performance, models at the 7B and 13B level can already run smoothly on ordinary laptops or workstations.
Quantization technology can reduce memory footprint and computation by 75–90% with almost no loss in accuracy.
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
