# Chain-of-Zoom: Extreme Image Super-Resolution Demo

This Space runs the [Chain-of-Zoom](https://github.com/bryanswkim/Chain-of-Zoom) model for extreme image super-resolution, optimized for both CPU and GPU environments.

## Setup Instructions
1. **Set HF_TOKEN**: Add a valid Hugging Face access token as `HF_TOKEN` in the Space's secrets to access gated models (`bryandmc/Chain-of-Zoom`, `stabilityai/stable-diffusion-3-medium-diffusers`).
2. **CPU/GPU Compatibility**:
   - For CPU: Use the default `python:3.10-slim` base image.
   - For GPU: Build with `--build-arg BASE_IMAGE=nvidia/cuda:11.8.0-cudnn8-runtime-ubuntu20.04` and update `requirements.txt` to use `torch==2.1.0+cu118`, etc.
3. **Commit Hash**: Ensure the `Chain-of-Zoom` repository is pinned to a valid commit (e.g., `a1b2c3d`) in the Dockerfile.

## Usage
Upload an image, select a magnification factor (2x-16x), provide an optional caption, and set a seed. The process may be slow on CPU.
