# 📖 Wan2.1 VACE + Phantom Lightx2V (Finetune)
**Author / Creator:** [Ciro_Negrogni](https://civitai.com/user/Ciro_Negrogni)
**Based on merge by:** [Inner_Reflections_AI](https://civitai.com/user/Inner_Reflections_AI)
**Original Guide:** [Wan VACE + Phantom Merge – Inner Reflections](https://civitai.com/articles/17908/guide-wan-vace-phantom-merge-an-inner-reflections-guide)
---
## 🔹 About This Finetune
This is the **Lightx2V variant of the VACE + Phantom merge**, created by **Ciro_Negrogni** and derived from Inner_Reflections_AI’s original merge.
Purified to **FP16** for WanGP compatibility and supplied with optional **INT8 quantization**.
- **Architecture:** `vace_14B`
- **Mode:** Image/Video conditioning with multi‑image reference support (2–4 refs in WanGP UI)
- **Variants:** FP16 (pure) and quanto INT8

## 🔹 Files
- `Wan2.1_VACE_Phantom_Lightx2V_fp16_pure.safetensors`
- `Wan2.1_VACE_Phantom_Lightx2V_quanto_fp16_int8.safetensors` *(or `_quanto_bf16_int8` depending on dtype)*

## 🔹 Usage in WanGP
Place the JSON definition in:
```
app/finetunes/vace_phantom_lightx2v.json
```
Example JSON snippet:
```json
