Core Innovation
This paper introduces ARCQuant, which augments activation matrices with quantized residual channels to maintain unified NVFP4 precision and block isolation. Unlike prior methods that compromise hardware uniformity or accuracy, ARCQuant integrates error compensation into matrix operations, enabling use of optimized GEMM kernels with minimal overhead and achieving error bounds comparable to 8-bit formats.
Why It Matters
Efficient LLM inference is critical for scaling AI applications while controlling compute costs. ARCQuant reduces model size and speeds up inference without sacrificing accuracy or requiring specialized hardware. This enables broader deployment of large language models in real-world applications, improving accessibility and operational efficiency.
