FLUX LoRA Extract

Follow 1st image in the top above images for config and learn how to extract

FLUX LoRA extraction can be useful or may not be useful

As you extract higher Network Dimension (Rank) you get better results

640 is what I found maximum but you can try further like 672 etc

However as you increase Rank, it will take more space

If you truly needs FLUX LoRA, I recommend both try extract and also solo training

FLUX LoRA Training Tutorial : https://youtu.be/nySGu12Y05k

Both tutorials and their configs and files are all up to date

Currently I recommend solo LoRA training but each case might be unique

Moreover, LoRA extraction fixes the stripe problem when you do 2x latent upscale

SDXL LoRA Extract

Follow the 2nd image in the top above images for config

If you need SDXL LoRA I really recommend SDXL DreamBooth and then extract LoRA

As you extract higher Network Dimension (Rank) you get better results

The last image very top shows you the difference of Network Dimension 128 vs 256 vs 512 vs original DreamBooth model

If still not sufficient, you can increase LoRA scale / power / weight slightly like 1.1, 1.2 etc

SDXL LoRA extract really works well and we don't have well researched SDXL LoRA config atm that will reach to DreamBooth then LoRA extract quality

Moreover, I really don't recommend SDXL since it is too inferior to FLUX so unless you have to go with FLUX training
