Unlike Stable Diffusion models, which usually come as a single checkpoint file, Flux models consist of a set of model files (UNet, VAE, CLIP, etc.). Downloading them and figuring out where each file belongs in the ComfyUI folder structure can be confusing and tedious.

ComfyDL solves this by automating the download and placement process with simple commands.

Quick Start

Install comfydl and set your ComfyUI root path:

pip install comfydl
comfydl set COMFYUI_ROOT /path/to/your/ComfyUI

Download the full Flux.1 suite:

comfydl flux1

Or the FP8 development version:

comfydl flux1_dev_fp8

Done! The tool handles the rest.

The Challenge with Flux Models

If you are transitioning from Stable Diffusion 1.5 or SDXL to the new state-of-the-art Flux models, you might have noticed the installation isn't as straightforward. A functional Flux setup in ComfyUI requires multiple components:

1. UNet/Transformer model: The core diffusion model.
2. CLIP/Text Encoders: Often multiple (e.g., t5xxl_fp16, t5xxl_fp8, clip_l).
3. VAE: The Variational Autoencoder.

Manually downloading these files from Hugging Face and placing them into models/unet, models/clip, and models/vae respectively—while ensuring you have the compatible versions—is error-prone.

The Solution: ComfyDL

ComfyDL is a Command Line Interface (CLI) tool designed specifically for ComfyUI users. It manages model sources and destination paths so you don't have to.

Key Features

• Automated Placement: Downloads files directly to the correct ComfyUI subdirectories.
• Preset Model Sets: Comes with built-in presets for popular models like Flux, Pony, SDXL, and Qwen.
• Resume Capability: Uses aria2c (recommended) or wget for robust downloads.
• Civitai Support: Can download models directly via version ID or URL.

Detailed Installation

Prerequisites

• Python 3.8+
• aria2c (Highly recommended for faster, resumable downloads) or wget.

Install via pip

pip install comfydl

Configuration

Tell ComfyDL where your ComfyUI is installed. This ensures files land in the right models/ folders.

comfydl set COMFYUI_ROOT /path/to/your/ComfyUI

(Optional) If you download restricted models, you can set your API tokens:

comfydl set CIVITAI_TOKEN your_civitai_token
comfydl set HF_TOKEN your_huggingface_token

Downloading Flux Models

Once installed, downloading Flux is as simple as running a single command.

For the standard Flux.1 set:

comfydl flux1

For the optimized Flux.1 Dev FP8 version:

comfydl flux1_dev_fp8

ComfyDL will fetch all the required text encoders (t5xxl, clip_l), the VAE, and the UNet model, placing them exactly where ComfyUI expects them.

Other Useful Commands

ComfyDL isn't just for Flux. You can use it for other popular models:

comfydl pony             # Download Pony Diffusion models
comfydl dreamshaper      # Download DreamShaper
comfydl common_vae       # Download common VAEs

You can also browse available models interactively by just running:

comfydl
