# HeliosTransformer3DModel

A 14B Real-Time Autogressive Diffusion Transformer model (support T2V, I2V and V2V) for 3D video-like data from [Helios](https://github.com/PKU-YuanGroup/Helios) was introduced in [Helios: Real Real-Time Long Video Generation Model](https://huggingface.co/papers/2603.04379) by Peking University & ByteDance & etc.

The model can be loaded with the following code snippet.

```python
from diffusers import HeliosTransformer3DModel

# Best Quality
transformer = HeliosTransformer3DModel.from_pretrained("BestWishYsh/Helios-Base", subfolder="transformer", torch_dtype=torch.bfloat16)
# Intermediate Weight
transformer = HeliosTransformer3DModel.from_pretrained("BestWishYsh/Helios-Mid", subfolder="transformer", torch_dtype=torch.bfloat16)
# Best Efficiency
transformer = HeliosTransformer3DModel.from_pretrained("BestWishYsh/Helios-Distilled", subfolder="transformer", torch_dtype=torch.bfloat16)
```
