AstolfoMix-XL (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.

TSD (TIES-SOUP w/ DROP)

• TSD Merge of 102 SDXL models, unfiltered. TSD is an algorithm modified from DARE Merge (ICML 2024)..

• Recipe, E2E merger.

• Current version: x101a-AstolfoMix-24050903-4edc67c.safetensors

• Recommended version: "x101a"

• Recommended CFG: 4.5 (with CHG = 1.0), 3.0 (with PAG = 1.0)

• Prompt is minimal. Even empty.
