发生了什么: What makes a high-quality NVFP4 quantization?

NVFP4 quantization quality depends on assigning 4-bit precision to robust layers and higher precision to sensitive layers using three methods.

为何重要: What makes a high-quality NVFP4 quantization?

Engineers optimizing large language models for inference speed and memory when deploying on GPUs with native FP4 support.

注意: What makes a high-quality NVFP4 quantization?

Isolated sensitivity scores can't be summed across layers because quantization loss saturates; SaturationQuant addresses this but requires more computation.
