This feature is available in versions 2.5.0 and higher
You can merge two Stable Diffusion models (in .ckpt or .safetensors formats), to combine features and art-styles from two different models.
Step 1
Open the Merge models tab, at the top of the UI:
Step 2
Select the two model files (which you want to merge):
Important: Please merge models of similar type. For e.g. SD 1.4 models with only SD 1.4/1.5 models, SD 2.0 with SD 2.0-type, and SD 2.1 with SD 2.1-type models.
Step 3
Choose the merge ratio. For e.g. a 5% merge ratio will result in 5% of Model A and 95% of Model B in the final merged model.
Step 4
Set the filename for the merged model, in the Output file name textbox. The merge ratio and file extension will be added automatically, you don't need to include them in the filename.
Finally, click the Merge models button to produce the merged model file(s).
That's it!
Advanced usage
You can also automatically create multiple merge files, at increasing merge ratios. This is useful for experimenting with different merge ratios.
Note: this will create one model file per merge ratio, so it can consume a lot of disk space quickly!
