SAW-INT4: System-Aware 4-Bit KV-Cache Quantization for Real-World LLM Serving

★★★★★ significance 3/5

The researchers propose SAW-INT4, a 4-bit quantization method for KV-cache designed to optimize LLM serving. The approach uses token-wise INT4 quantization with block-diagonal Hadamard rotation to maintain high accuracy while remaining compatible with real-world serving constraints like paged memory layouts.

Why it matters Optimizing KV-cache efficiency through system-aware quantization is critical for reducing memory bottlenecks in high-throughput, large-scale LLM deployment environments.
