Lora
This project is a toolkit for fine-tuning and managing text-to-image diffusion models. It focuses on low-rank adaptation to create small, portable weight files that customize model styles and behaviors without modifying the entire base model.
The project provides specialized utilities for model distillation using singular value decomposition to extract adapters from fully trained models, as well as tools for blending and merging multiple adapters through weight interpolation. It includes capabilities for subject inversion and pivotal tuning to increase the visual fidelity of specific identities.
Additional capabilities cover the transformation of model weights between different storage formats for cross-engine compatibility. The toolkit also supports training for image inpainting and the co-training of text encoders to improve the association between specific tokens and visual concepts.
