A new framework called Asymmetric Key-Value Cache Compression has been developed to address the memory bandwidth bottleneck faced by large language models with expanded context windows. This approach decouples the quantization of Key and Value components of the cache, which can otherwise swell to over a terabyte for large models. By employing Omni-Scaled Canalized Rotation (OScaR) to neutralize token norm imbalance, the framework achieves a significant reduction in memory footprint and a notable speedup in decoding with no loss in linguistic performance.
