FLUX.2-dev Model Setup Guide
a. Model Links and Storage Locations
Chunked loading is recommended as it better aligns with ComfyUI's standard workflow.
1. Chunked Loading Weights (Recommended)
For chunked loading, it is recommended to directly download the FLUX.2-dev weights provided by ComfyUI official. Please organize the files according to the following directory structure:
Core Model Files:
| Component | File Name |
|---|---|
| Text Encoder | mistral_3_small_flux2_bf16.safetensors |
| Diffusion Model | flux2_dev_fp8mixed.safetensors |
| VAE | flux2-vae.safetensors |
| tokenizer | tokenizer |
ControlNet Model Files:
| Name | Storage | Hugging Face | Model Scope | Description |
|---|---|---|---|---|
| FLUX.2-dev-Fun-Controlnet-Union | - | 🤗Link | 😄Link | ControlNet weights for FLUX.2-dev, supporting multiple control conditions such as Canny, Depth, Pose, MLSD, Scribble, etc. |
Storage Location:
📂 ComfyUI/
├── 📂 models/
│ ├── 📂 text_encoders/
│ │ └── mistral_3_small_flux2_bf16.safetensors
│ ├── 📂 diffusion_models/
│ │ └── flux2_dev_fp8mixed.safetensors

│ │ └── flux2_tokenizer/
│ └── 📂 model_patches/
│ └── FLUX.2-dev-Fun-Controlnet-Union-2602.safetensors
2. Preprocessing Weights (Optional)
If you want to use the control preprocessing nodes, you can download the preprocessing weights to ComfyUI/custom_nodes/Fun_Models/Third_Party/.
Required Files:
| File Name | Download Link | Purpose |
|---|---|---|
yolox_l.onnx |
Download | YOLO Detection Model |
dw-ll_ucoco_384.onnx |
Download | DWPose Pose Estimation Model |
ZoeD_M12_N.pt |
Download | ZoeDepth Depth Estimation Model |
Storage Location:
📂 ComfyUI/
├── 📂 models/
│ └── 📂 Fun_Models/
│ └── 📂 Third_Party
│ ├── yolox_l.onnx
│ ├── dw-ll_ucoco_384.onnx
│ └── ZoeD_M12_N.pt
3. Full Model Loading (Optional)
If you prefer full model loading, you can directly download the diffusers weights.
Required Files:
| Name | Storage | Hugging Face | Model Scope | Description |
|---|---|---|---|---|
| FLUX.2-dev | 🤗Link | 😄Link | Official FLUX.2-dev weights |
For full model loading, use the diffusers version of FLUX.2-dev Turbo and place the model in ComfyUI/models/Fun_Models/.

├── 📂 models/
│ └── 📂 Fun_Models/
| └── 📂 FLUX.2-dev/
b. ComfyUI Json Workflows
1. Chunked Loading (Recommended)
