wan22-t2v-a14b-modelopt-fp8-sglang-transformer

This repository contains the SGLang-native ModelOpt FP8 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:

sglang generate \
  --model-path Wan-AI/Wan2.2-T2V-A14B-Diffusers \
  --transformer-path lmsys/wan22-t2v-a14b-modelopt-fp8-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=FP8.
• —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.
