Yamano Mitsuha [Anima Base 1]

V1.1: I didn't notice I accidentally trained on both unet and TE. Obviously for a lora like this the TE layers are 100% unnecessary, therefore I've stripped them out for this new version. If nothing else - just to avoid the 'lora key not loaded' spam in comfyui log.

Trained with only booru tags on a dataset of ~70 quickly hand picked screenshots with VLC without even cropping.

It was supposed to be a test but it turned out so well that I'm sharing it.

I can't believe how easy it is to train characters on Anima. In comparison with my LTX lora - this is like 'level 1' and the other is level 300 or something xD No challenge whatsoever here. Throw LR = 0.0001 or LR = 0.00005 - hardly matters because both will work. 200 images or just 30 it looks as though it won't matter much as well. Ignore the average loss curve - means nothing as usual.

Trained on kohya sd-scripts.

Training command and config (for reference) - Updated to use flash_attn, vae disk cache and unet training only - the rest remains exactly the same as I used:
