Researchers have introduced CoQuant, a novel method for mixed-precision quantization in Large Language Models (LLMs). This technique addresses limitations in existing approaches by jointly considering both weight and activation statistics to identify critical subspaces for high-precision preservation. CoQuant utilizes a theoretically modeled error and a weighted PCA solution to balance these covariances, aiming to reduce inference costs more effectively. Experiments on Llama-3.2 and Qwen2.5 models demonstrate CoQuant's superior performance in perplexity and reasoning accuracy compared to current post-training quantization baselines. AI
