arXiv:2605.08692v2 Announce Type: replace Abstract: Post-training weight-only quantization to 4 bits is widely used to reduce the memory and compute costs of large language model inference. Existing PTQ methods, such as AWQ and GPTQ, improve how weights are mapped onto a fixed 4-bit grid through scaling, clipping, or error compensation. To further improve accuracy, methods such as OmniQuant and QuIP\# uses gradient-assisted algorithms at the cost of hours of quantization time. In this work, we propose AAAC (Activation-Aware Adaptive Codebooks), a lightweight method for 4-bit LLM weight quantiz
The rapid growth of large language models necessitates continuous innovation in efficiency to make them more accessible and economical.
This development allows for significant reductions in memory and compute costs for LLM inference, broadening their deployment, especially in resource-constrained environments.
New methods for 4-bit quantization are achieving better accuracy with less computational overhead during quantization, addressing a key bottleneck for wider LLM adoption.
