Qwen3-Next-80B-A3B-Instruct-NVFP4

Quantized version of Qwen/Qwen3-Next-80B-A3B-Instruct using LLM Compressor and the NVFP4 (E2M1 + E4M3) format.

This time it actually works! We think

This should be the start of a new series of hopefully optimal NVFP4 quantizations as capable cards continue to grow out in the wild.
