+# Qwen-Image-2.1-GGUF
+
+Direct GGUF conversion of [Qwen/Qwen-Image-2.1](https://huggingface.co/Qwen/Qwen-Image-2.1) ([Comfy-Org repackaged weights](https://huggingface.co/Comfy-Org/Qwen-Image-2.1)).
+
+These model files are optimized for use in [ComfyUI](https://github.com/comfyanonymous/ComfyUI) using the [ComfyUI-GGUF](https://github.com/city96/ComfyUI-GGUF) custom node ().
+
+## Models
+
+| File Name | Quantization | Size | Description |
+| :--- | :--- | :--- | :--- |
+| `qwen_image_2.1_Q8_0.gguf` | Q8_0 | ~7.10 GB | 8-bit quantized model preserving 99.9% quality, with F32 1D norms and BF16 sensitive I/O projection layers |
+
+## Setup & File Placement in ComfyUI
+
+Place the downloaded files in your ComfyUI directory:
+
+```
+📂 ComfyUI/
+└── 📂 models/
+    ├── 📂 diffusion_models/ (or models/unet/)
+    │   └── qwen_image_2.1_Q8_0.gguf
+    ├── 📂 text_encoders/
+    │   └── qwen3vl_8b_bf16.safetensors (or quantized variant)
+    └── 📂 vae/
+        └── qwen_image_2.1_vae_bf16.safetensors
+```
+
+## Usage in ComfyUI
+
+1. Install [ComfyUI-GGUF](https://github.com/city96/ComfyUI-GGUF).
+2. Use the **`Unet Loader (GGUF)`** node instead of the standard `UNETLoader` or `DiffusionModelLoader`.
+3. Select `qwen_image_2.1_Q8_0.gguf`.
+4. Connect the MODEL output to your KSampler / Guider pipeline.
