InstantStyle: Free Lunch towards Style-Preserving in Text-to-Image Generation

""" description = r""" Official 🤗 Gradio demo for InstantStyle: Free Lunch towards Style-Preserving in Text-to-Image Generation.
How to use:
1. Upload a style image. 2. Set stylization mode, only use style block by default. 2. Enter a text prompt, as done in normal text-to-image models. 3. Click the Submit button to begin customization. 4. Share your stylized photo with your friends and enjoy! 😊 Advanced usage:
1. Click advanced options. 2. Upload another source image for image-based stylization using ControlNet. 3. Enter negative content prompt to avoid content leakage. """ article = r""" --- 📝 **Citation**
