A developer has released Signet Trainer, a from-scratch rebuild of a video/image LoRA trainer, now open-source on GitHub. The tool focuses specifically on models and workflows the author uses in daily practice.
Currently supported models and features:
- MiniMax H3: Includes reference image IC-LoRA training.
- LTX 2.3: Offers a fuller IC-LoRA feature set.
- In Progress: LTX 2.5 is being implemented; Wan 2.1 and Qwen / Qwen-Image-Edit are on beta branches.
The author notes that the trainer architecture was heavily shaped by musubi-tuner and ostris/ai-toolkit.
