wan22-t2v-a14b-modelopt-nvfp4-sglang-transformer

This repository contains the SGLang-native ModelOpt NVFP4 transformer override for Wan-AI/Wan2.2-T2V-A14B-Diffusers.

It is intended to be used with SGLang Diffusion through --transformer-path while keeping the base model separate:

bash

sglang generate \
  --model-path Wan-AI/Wan2.2-T2V-A14B-Diffusers \
  --transformer-path lmsys/wan22-t2v-a14b-modelopt-nvfp4-sglang-transformer \
  --prompt "A cinematic scene with detailed lighting" \
  --save-output

Contents

The repository is intentionally minimal and contains only:

config.json
*.safetensors weight shard files
*.safetensors.index.json when the checkpoint is sharded

Validation images, benchmark outputs, profiler traces, and conversion scratch artifacts are not stored in this model repository.

Notes

Quantization config is stored in config.json with quant_method=modelopt and quant_algo=NVFP4.
Use this checkpoint with an SGLang version that includes diffusion ModelOpt support for the corresponding model family.
The original base model license and usage terms still apply.
