# Recipe

1. Merge using `sd-mecha for ComfyUI`. ( below sd-mecha format recipe )
```
model "sdxl\illustrious_pencil-XL-v2.0.0.safetensors" "sdxl" "base"
model "sdxl\noobaiXLNAIXL_vPred075SVersion.safetensors" "sdxl" "base"
model "sdxl\noobaiXLNAIXL_epsilonPred10Version.safetensors" "sdxl" "base"
merge "train_difference" &0 &1 &2 alpha=1.1
merge "clamped_add_opposite" &3 &0 &2 alpha=0.25
merge "add_cosine_a" &1 &4 alpha=1.0
merge "slerp" &3 &5 alpha=0.65
```

2. Add `v_pred` and `ztsnr` keys.

```python
BASE_MODEL_NAME = "noob_v_pencil-XL-0.75s"
tensors = {}
with safe_open(BASE_MODEL_NAME + "-base.safetensors", framework="pt", device="cpu") as f:
    for key in f.keys():
        tensors[key] = f.get_tensor(key)
tensors["v_pred"] = torch.tensor([0.0])
tensors["ztsnr"] = torch.tensor([0.0])
save_file(tensors, BASE_MODEL_NAME + ".safetensors")
```
