# flux1-dev

> flux1-dev - Comfy-Org 在 ModelScope 开源的模型。Repackaged model files for ComfyUI.

Comfy-Org/flux1-dev 是 ModelScope 魔搭社区上的 60.6B 参数text-to-image-synthesis模型，采用 other 许可，基于 black-forest-labs/FLUX.1-dev、black-forest-labs/FLUX.1-Canny-dev、black-forest-labs/FLUX.1-Depth-dev 构建。

# FLUX.1-dev

Repackaged model files for ComfyUI.

Original model repository: https://huggingface.co/black-forest-labs/FLUX.1-dev

Place the files in the following folders:

```
📂 ComfyUI/
├── 📂 models/
│   ├── 📂 checkpoints/
│   │   ├── flux1-dev-fp8.safetensors
│   │   └── flux1-dev.safetensors
│   ├── 📂 diffusion_models/
│   │   ├── flux1-canny-dev.safetensors
│   │   ├── flux1-depth-dev-nvfp4.safetensors
│   │   └── flux1-fill-dev.safetensors
│   ├── 📂 loras/
│   │   └── flux1-depth-dev-lora.safetensors
```

---

This is a smaller checkpoint for flux1-dev that will work better for ComfyUI users with less VRAM (under 24gb). 

The two text encoders used by Flux are already included in this one safetensor.

Use it with the `Load Checkpoint` node in ComfyUI.
