## These are several flavors of the piece of the SDXL Refiner model that Mochi Diffusion needs to turn a SDXL Base model into a combined Base + Refiner model.

Put the correct version of the UnetRefiner.mlmodelc in with the rest of the pieces of your Base model.  Mochi will automatically recognize the 2 Unets as a combineed model.

It will use the Base model Unet for the first 80% of the steps and then it will automatically switch to the Refiner model Unet for the final 20%.  The transition point is hardcoded.

Take care when unzipping after downloading as they all unzip to the same UnetRefiner.mlmodelc name.


**Keep in mind that the Refiner is a generic type model and using it with a Base model that has a specific "personality" might ruin rather than improve images.**
