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

• To install Kohya use installer from here : https://www.patreon.com/posts/112099700

• FLUX DreamBooth / Fine Tuning tutorial : https://youtu.be/FvpWy1x5etM

• 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

• Latent upscale tutorial and quality difference shown here : https://youtu.be/Xbn93GRQKsQ

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
