How To Use SDXL Lightning In Fooocus - Stable Diffusion

Stable Diffusions Newest Speedy Model Is SDXL Lightning. Here I will show you how to get it working in Fooocus so you can try it out for yourself.

Use this like the Turbo model (change checkpoint to new Dreamshaper Lightning model)

CFG 1-2
sampler: dpmpp_sde
scheduler: Karras
steps 3-6
resolution 1024x1024 recommended
-------
**Update2**
The Bytedance/SDXL-Lightning files were updated to safetensors. There is also a checkpoint model available for use. All the same settings still apply for these (sgm_uniform/Euler/cfg-1/etc).
Only use the model or the Lora, not together.
So far Lora looks better to me.

Enjoy!

Thanks for this tutorial, your videos are very easy to follow and easy to understand. One question, how can I make wildcards for faces? Have you made a video for this? Thanks!

Hello, Great videos, question is the Lightning release same as Turbo. Just for personal use. Do you need a licenses? Thank you, William

I would like to know how to select a VAE using Fooocus, if there is a way or something.

can you show how to fix hand and finger on Focus ?

How did you create a woman with just typing _jess_ 😮

🎯 Key Takeaways for quick navigation:

00:00 *SDXL Lightning, a new research model by ByteDance, offers quick, low-step generations, capable of producing usable results from eight steps down to one.*
00:26 *Two workflows for SDXL Lightning: using the UNet model or the Lura model, with Focus supporting only the Lura model.*
00:55 *Download the Lura model files corresponding to the number of steps you want to use, and place them in the Focus model Lura folder.*
01:33 *Configure Focus with the chosen Lura model, adjusting guidance scale, sharpness, sampler, and forced overwrite of sampling steps according to the Lura model's step count.*
02:33 *Initial tests show that while SDXL Lightning's detail may not match that of turbo models or LCMs, it potentially offers a better outcome than the extreme speed setting.*
03:20 *Early results suggest possible optimizations could make SDXL Lightning a competitive option, with more testing needed to find optimal settings.*
