Introduction 📖
This repo, named CSGO, contains the official PyTorch implementation of our paper CSGO: Content-Style Composition in Text-to-Image Generation. We are actively updating and improving this repository. If you find any bugs or have suggestions, welcome to raise issues or submit pull requests (PR) 💖.
Pipeline 💻
Capabilities 🚅
🔥 Our CSGO achieves image-driven style transfer, text-driven stylized synthesis, and text editing-driven stylized synthesis.

Getting Started 🏁
1. Clone the code and prepare the environment
git clone https://github.com/instantX-research/CSGO
cd CSGO
# create env using conda
conda create -n CSGO python=3.9
conda activate CSGO
# install dependencies with pip
# for Linux and Windows users
pip install -r requirements.txt
2. Download pretrained weights(coming soon)
The easiest way to download the pretrained weights is from HuggingFace:
# first, ensure git-lfs is installed, see: https://docs.github.com/en/repositories/working-with-files/managing-large-files/installing-git-large-file-storage
git lfs install
# clone and move the weights
git clone https://huggingface.co/InstanX/CSGO CSGO
Our method is fully compatible with SDXL, VAE, ControlNet, and Image Encoder. Please download them and place them in the ./base_models folder.
