| <b>Official 🤗 Gradio demo</b> for <a href='https://github.com/InstantID/InstantID' target='_blank'><b>InstantID: Zero-shot Identity-Preserving Generation in Seconds</b></a>.<br> | |
| How to use:<br> | |
| 1. Upload an image with a face. For images with multiple faces, we will only detect the largest face. Ensure the face is not too small and is clearly visible without significant obstructions or blurring. | |
| 2. (Optional) You can upload another image as a reference for the face pose. If you don't, we will use the first detected face image to extract facial landmarks. If you use a cropped face at step 1, it is recommended to upload it to define a new face pose. | |
| 3. (Optional) You can select multiple ControlNet models to control the generation process. The default is to use the IdentityNet only. The ControlNet models include pose skeleton, canny, and depth. You can adjust the strength of each ControlNet model to control the generation process. | |
| 4. Enter a text prompt, as done in normal text-to-image models. | |
| 5. Click the <b>Submit</b> button to begin customization. | |
| 6. Share your customized photo with your friends and enjoy! 😊""" | |

| ### Usage tips of InstantID | |
| 1. If you're not satisfied with the similarity, try increasing the weight of "IdentityNet Strength" and "Adapter Strength." | |
| 2. If you feel that the saturation is too high, first decrease the Adapter strength. If it remains too high, then decrease the IdentityNet strength. | |
| 3. If you find that text control is not as expected, decrease Adapter strength. | |
| 4. If you find that realistic style is not good enough, go for our Github repo and use a more realistic base model. | |
