FastDM/Wan2.2-T2V-A14B-Merge-Lightning-V1.0-Diffusers

This model is a merger of Wan-AI/Wan2.2-T2V-A14B-Diffusers and Wan2.2-Lightning v1 model, it can be run with diffusers pipeline.

Running with FastDM:

python gen.py --model-path FastDM/Wan2.2-T2V-A14B-Merge-Lightning-V1.0-Diffusers --architecture wan --guidance-scale 1.0 --height 720 --width 1280 --steps 4 --use-fp8 --output-path ./wan-a14b-lightningv1.1-fp8-guid1.mp4 --num-frames 81 --fps 16 --prompts "Two anthropomorphic cats in comfy boxing gear and bright gloves fight intensely on a spotlighted stage."

Running with diffusers:

from diffusers.utils import export_to_video, load_image

dtype = torch.bfloat16
device = "cuda:2"
vae = AutoencoderKLWan.from_pretrained("FastDM/Wan2.2-T2V-A14B-Merge-Lightning-V1.0-Diffusers", subfolder="vae", torch_dtype=torch.float32)
pipe = WanPipeline.from_pretrained("FastDM/Wan2.2-T2V-A14B-Merge-Lightning-V1.0-Diffusers", vae=vae, torch_dtype=dtype)
pipe.to(device)

height = 720
