This model uses the SDXL Hyper LoRA in it, and has the SDXL VAE baked into it. The LCM SGM Uniform sampler seems to work best for me, but experiment with what works for you; Euler A seems to work nicely too. This checkpoint was trained with a lot of Honkai Star Rail stuff (among many other things), so it might work as a decent character checkpoint; in case you don't get the character that you want, it's advisable to use the appropriate character LoRA.
