Train difference is explained here https://github.com/hako-mikan/sd-webui-supermerger/blob/main/calcmode_en.md#train, and is what allows this model to exist. TLDR, this model uses the a1111 supermerger extension to merge 526Mix with FluffyRock vpred using these settings: 526Mix is set as model A, fluffyrock vpred as model B, v1-5-pruned (sd base model) as model C, add difference as the merge mode, train difference as the calculation mode, alpha is set to 1, and the output is saved as fp16 safetensors.
This model requires a config and CFG Rescale. Download the config file and put it next to the regular model in your stable diffusion models folder. If you use a1111, install the CFG Rescale extension here: https://github.com/Seshelle/CFG_Rescale_webui. If you use comfy, download the sampler_rescalecfg file from here https://github.com/comfyanonymous/ComfyUI_experiments and put it in your custom nodes folder. Recommended settings are 7.5 for CFG and 0.7 for CFG Rescale.
