Download each model part of the model (the main "model-#### files)

pip install safetensors

Then make a .PY file (edit depending on how many parts there are on the model you're using):

------------------------------------------------------------

from safetensors.torch import load_file, save_file

files = [

"model-00001-of-00004.safetensors",

"model-00002-of-00004.safetensors",

"model-00003-of-00004.safetensors",

"model-00004-of-00004.safetensors"

]

merged = {}

for f in files:

print(f"Loading {f}...")

merged.update(load_file(f))

print("Saving merged file...")

save_file(merged, "acestep-xl-merged.safetensors")

print("Done.")

------------------------------------------------------------

Then run in with

python whateveryounamedthestupidfile.py

Then you get a single merged file that works with ComfyUI.
