The 3D variational autoencoder (VAE) model with KL loss used in HunyuanVideo, which was introduced in HunyuanVideo: A Systematic Framework For Large Video Generative Models by Tencent.
The model can be loaded with the following code snippet.
from diffusers import AutoencoderKLHunyuanVideo
vae = AutoencoderKLHunyuanVideo.from_pretrained("hunyuanvideo-community/HunyuanVideo", subfolder="vae", torch_dtype=torch.float16)
