All images out of the box, no postprocessing. Model
works best with high sampling levels. Larger resolutions
are also working good. If you have enough vram sometimes
no upscaler needed.
Recommendations (default use):
Optimum CFG-Scale: 7
Optimum Sampling Level: 150
Sampler Best Results:
Euler a
DPM++ 2S a Karras
DPM++ 3M SDE
DPM2 a Karras

The model is highly optimized on the settings
above, so you should leave out quality prompts
first, if not necessary.
The model is build of the latest trained models
and lora, thanks to all community members
for their work.
I hope you enjoy and share your images.
Ultrium is always a merge of the best and/or latest
avaiable models. So each Ultrium is different than
its predecessors. It's your decision if or which
Ultrium is best for you.
Ultrium 9.333 will be the last Ultrium for SDXL 1.0,
I will see for which AI I continue my work.

Tried to replicate one of your showcase images - along with a bunch of other prompts - but all of them are giving me the issue seen in the post I uploaded in the examples. Issue related to using the Civit web UI, or something else going on?
I have tested your Image, it seems related to your negative prompt. If you remove the last "," at the end of the line it gets better. You should avoid heavy negative prompts, if not needed and the image quality will further increase.
I usually get those types of images when the vae isn't baked into the model or loaded
@zathoros VAE is baked, if not a the prompt is the issue it could be a missing vae or a wrong vae - f.e. SD1.5 VAE for SDXL.
@DSchroeder, can you please upload the pruned model for version 6? Currently only the 12.92 GB version is available to download.
I keep getting black blanks, I can't figure out what causes this. I have it set to 7.5 CFG, 20 S. Steps.
black blanks usually indicates a NaN error from fp16 overruns. ensure you're using the correct VAE from here: https://huggingface.co/madebyollin/sdxl-vae-fp16-fix/tree/main
you specifically want the "sdxl.vae.safetensors" file. His page is a slight mess for some reason.
