| """**Main Features**<br>- Fine-tune Stable diffusion models twice as faster as Dreambooth method by Low-rank Adaptation.<br>- Get insanely small end results, easy to share and download.<br>- Easy to use, compatible with diffusers.<br>- Sometimes even better performance than full fine-tuning<br><br>Please refer to the GitHub repo this Space is based on, here - <a href = "https://github.com/cloneofsimo/lora">LORA</a>. You can also refer to this tweet by AK to quote/retweet/like here on <a href="https://twitter.com/_akhaliq/status/1601120767009513472">Twitter</a>.This Gradio Space is an attempt to explore this novel LORA approach to fine-tune Stable diffusion models, using the power and flexibility of Gradio! The higher number of steps results in longer training time and better fine-tuned SD models.<br><br><b>To use this Space well:</b><br>- First, upload your set of images (suggested number of images is between 4-9), enter the prompt, enter the number of fine-tuning steps (suggested value is between 2000-4000), and then press the 'Train LORA model' button. This will produce your fine-tuned model weights.<br>- Modify the previous prompt by adding to it (suffix), set the alpha value using the Slider (nearer to 1 implies overfitting to the uploaded images), and then press the 'Inference' button. This will produce an image by the newly fine-tuned UNET and Text-Encoder LORA models.<br><b>Bonus:</b>You can download your fine-tuned model weights from the Gradio file component. The smaller size of LORA models (around 3-4 MB files) is the main highlight of this 'Low-rank Adaptation' approach of fine-tuning.""") | |
