ReQuant refines quantized LLMs without backpropagation, boosting performance

Researchers have developed ReQuant, a novel post-training quantization (PTQ) method that refines existing quantized models without requiring backpropagation. This technique iteratively improves discrete weight assignments on a fixed grid, reducing reconstruction error and enhancing model performance. Experiments demonstrate that ReQuant consistently boosts the quality of quantized models across various architectures and bit-widths, even surpassing methods like GPTAQ when applied to simpler initializations.
