This repository will contains the needed safetensors to upgrade SDXL models based on Illustrious XL when new versions are released.

Since a lot of SDXL models are now based on Illustrious XL, each time a new version is released, it is painful to "upgrade" our merged models to benefit from the new capabilities.

Here, i'll store my "helpers" for my own method of upgrade:
- Replace the CLIP of the model with the new CLIP using a 0.8~0.9 weighted sum (so replacing it with most of the new CLIP but still keeping a bit of the original model)
- Merge provided LoRAs at preferred strength to update the UNET (the LoRAs are UNET only and built using SVD with Kohya_ss script using Illustrious checkpoints)

Provided safetensors (for now):
- Illustrious XL V2.0 CLIP: illus2-clip.safetensors
- V0.1 to V1.0 UNET LoRA: ZeroOne_To_OneZero.safetensors
- V1.0 to V2.0 UNET LoRA: OneZero_To_TwoZero.safetensors

Example procedure to upgrade a model based on V0.1 to V2.0:
- Replace the CLIP using python script (will be provided later)
- Merge both LoRAs at strength 0.8 (using Kohya_ss Pluslora.py)
