    Ultra Universalis - 16-Steps SDXL bySiLAS

    A Checkpoint for creating everything, beautiful and Photorealistic

    Reslotuion: 968*1408 with Kohya HRFix

    Sampler: Euler A + Karras

    or Euler a - Exponential

    Steps: 16 - not more - not less

    CFG: 1.5-3.5 (2.8 is fine for most)

    One of the advantages of this Model is - you don't need Loras to achieve stunningly beautiful Results, all you need is only this Model, try it and have Fun !

    I dont want to make Money with this so i dont ask for something, but if you want to help because you like my Model (which i hope) - let me know it... I would be thankful for any Buzz i got.... but its fine if you dont buzz but please do a friendly comment and... You are welcome to give a Thumb-Up !

    Thank you

    Base SD XL checkpoints are rare so I thought I would try this one out. The opening crowd image really impressed me. On the positive side, it has very good face variation and seems to handle fingers and toes well. But you absolutely must follow the author’s specific steps and CFG. If you normally use these values to tweak output – well its not happening. I would also suggest using the normal scheduler rather than the Karras. I tested multiple prompts and resolutions because I do like many of its generations, but it has other issues such as hyper “crunchy” details that ruin the output. For example: “a motorcycle racing down the Los Angeles coast” adds hundreds of cargo containers embedded into the hillside, wood has an artificial appearance, cloth can look hedge maze and skin can have too much detail. Add in the over sized eyes (starting at CFG 3) and you have a variation of the uncanny valley that is unique to AI. If you are looking for a better general purpose SD XL model, I would recommend the Epic Realism, Juggernaut or Stable Yogi models. Note, my review is based on output from ComfyUI which could be enhancing these issues.
