AstolfoMix-XL (215c / DGMLA-216 / TGMD-192 / TGMD / TSD / TIES-SOUP / Extended-FP64 / Baseline)

Unsolved merge, even with experience on SD1 and SD2.
See full article in Github
Since "Extended-FP64", dedicated merger sd-mecha is used. It is the SD version of mergekit.
Preview here are powered by the top session of README.md and converting SDXL model from A1111 standalone file into diffuers via convert_sdxl_to_diffusers.py. Settings may not being optimal (no CFG / PAG / FreeU etc). I'll replace the preview diffuser as soon as I upload the main model file.

DGMLA in nutshell

This algorithm should be linear a.k.a O(N) in space, and O(NlogN) in time complexity. However layerwise merging introduce some constants skewing the actual experience.
