LogQuant: Log-Distributed 2-Bit Quantization of KV Cache with Superior Accuracy Preservation
LogQuant applies log-based filtering for 2-bit KV cache quantization in LLMs, claiming 25% higher throughput, 60% larger batches, and 40-200% accuracy gains on math/code tasks versus existing compression approaches.
