# GenEx-World-Initializer 🧭🌍

**GenEx World Initializer** is panorama generation pipeline built on top of the [FluxFillPipeline](https://huggingface.co/black-forest-labs/FLUX.1-Fill-dev).

It transforms a **single view image** into a **360° panoramic image** using vision-conditioned inpainting.

- 🖼️ Input: One image (any size, will be center-cropped to square)
- 🧠 Prompt: Optional text to guide panoramic generation
- 🎯 Output: 2048 × 1024 equirectangular image
- 🧩 Mask: Uses a fixed panoramic mask

## 📦 Usage

```python
from diffusers import DiffusionPipeline
from PIL import Image
import torch

pipe = DiffusionPipeline.from_pretrained(
    "genex-world/World-Initializer-image-to-panorama",
    custom_pipeline="genex_world_initializer_pipeline",  
    torch_dtype=torch.bfloat16,
    trust_remote_code=True
).to("cuda")

# Load your image (any resolution)
image = Image.open("example_input.jpg")

# Run inference
front_view, output = pipe(image=image)
output.images[0]
```

## 🏁 Mask
The following mask is used to train the inpainting diffuser and used to inference automatically.
