Four Over Six: More Accurate NVFP4 Quantization with Adaptive Block Scaling
Paper • 2512.02010 • Published
Quantized NVFP4 version of Mistral-Nemo-Instruct-2407 with the down_proj tensors calibrated in FP8_DYNAMIC and the rest using Four Over Six adaptive block scaling, created to compare against my hybrid quant. Made with the same version of llm-compressor and compressed-tensors, using the same calibration data, to isolate the variables as much as possible.
