Researchers have developed OScaR, a new framework for compressing the Key-Value (KV) cache in Large Language Models (LLMs). This compression is crucial for handling the increasing memory demands of long-context reasoning and multi-modal capabilities. OScaR addresses the limitations of existing per-channel quantization methods by introducing Canalized Rotation and Omni-Token Scaling to mitigate token norm imbalance, achieving near-lossless performance even at INT2 quantization levels. The framework offers significant improvements, including up to a 3.0x speedup in decoding and a 5.3x reduction in memory footprint. AI
