# GenEx-World-Explorer 🚀🌍

**GenEx World Explorer** is a video generation pipeline built on top of [Stable Video Diffusion (SVD)](https://huggingface.co/stabilityai/stable-video-diffusion-img2vid-xt-1-1).
. It takes a keyframe, and generates a temporally consistent video. This explorer version builds on SVD with a custom `UNetSpatioTemporalConditionModel`.

The diffuser generate a forward moving path of a panoramic input image, to explore a given scene.

## 📦 Usage

```python
from diffusers import UNetSpatioTemporalConditionModel, StableVideoDiffusionPipeline
import torch
from PIL import Image

model_id = 'genex-world/GenEx-World-Explorer'

# Load the custom UNet
unet = UNetSpatioTemporalConditionModel.from_pretrained(
    model_id,
    subfolder='unet',
    torch_dtype=torch.float16,
    low_cpu_mem_usage=True,
)

# Load the full pipeline with custom UNet
pipe = StableVideoDiffusionPipeline.from_pretrained(
    model_id,
    unet=unet,
    low_cpu_mem_usage=True,
    torch_dtype=torch.float16,
    local_files_only=True,
).to('cuda')

# Explore the world!
image = Image.open('example.png').resize((1024, 576), Image.BICUBIC).convert('RGB')

generator = torch.manual_seed(-1)
with torch.inference_mode():
    frames = self.pipe(image,
                num_frames=25,
                width=1024,
                height=576,
                decode_chunk_size=8, generator=generator, motion_bucket_id=127, fps=7, num_inference_steps=30, noise_aug_strength=0.02).frames[0]
