A new research project, KLQ, introduces a training-free method for quantizing large language models. This approach measures the unevenness of embedding spaces and optimally allocates bit-widths to different directions based on their importance, measured by KL divergence. Unlike previous methods that rely on variance or learnable rotations, KLQ directly assesses the empirical cost of damaging specific directions. While effective, the method is computationally intensive, requiring numerous forward passes to quantize a model. AI
