Do not use these styles with other SDXL models, you just won't see any effect, These styles are for Pony Models only!
It's kind of an experiment, like why not? Why not train the model on just one image?
Styles are as stable as possible for just one image
Styles are a bit unstable but it's not related to LoRA, it's more related to the Pony Diffusion V6 XL model.
Recommended LoRA Strength: 1 (Strength can be reduced to 0.7 below this value I do not recommend it)
About OIS-s
JPEG compression artifacts were removed and training settings and network size were changed, LoRA is now half the size and style quality is also better (Styles are more similar to the original images)
Styles are based on images created by the AI
