In three linesUniSVQ introduces unified 2-bit quantization for LLMs combining scalar and vector quantization benefits through affine transforms of integer lattices. Block-wise fine-tuning strategy minimizes reconstruction error. Experiments across LLM families show outperformance vs state-of-the-art SQ methods and comparable performance to advanced VQ, with higher inference throughput.Read source
