The merging execution helper (meh) is a python module for stable diffusion models merging. This repository will never contain code for a webui extension. This is because the aim is to have a GUI agnostic merging engine that can be reused in multiple extensions.

You can install the module as

pip install sd-meh

and then use it in your extension as

from sd_meh.merge import merge_models

merged_model = merge_models(models, weights, bases, merge_mode, precision)

You can have a look at the provided merge_models.py cli for an example on how to use the function. Run python3 merge_models.py --help for a list of the available arguments.
