I merged SDXL Turbo with a lot of other top rated models on this site using a technique I implemented here from "Language Models are Super Mario: Absorbing Abilities from Homologous Models as a Free Lunch".

Supports LCM, SD Turbo, SD XL, 1024 res. The technique says it's for language models but it's generic.

No refiner necessary.
