# LoRA Fuser (FLUX.1-dev)

This model is designed to harmonize conflicting relationships when multiple LoRA models are loaded simultaneously, preventing image degradation.

For details, please refer to our paper: [AutoLoRA: Automatic LoRA Retrieval and Fine-Grained Gated Fusion for Text-to-Image Generation](https://arxiv.org/abs/2508.02107)

**We are still optimizing this model. The current version may produce unstable results with certain LoRAs. Please stay tuned for future updates.**
