• Seamless ComfyUI Integration: Works as a native custom node within ComfyUI, easily incorporated into your existing workflows.
• Improved Prompt Detail: Expands simple prompts into elaborate and nuanced descriptions, leading to more detailed and visually appealing images.
• Inspired by Fooocus: Faithfully adapted from the original Fooocus project and the LykosAI - GPT-Prompt-Expansion-Fooocus-v2 resource.
• Ready-to-Use Workflow: Includes a complete ComfyUI workflow example (see below) to get you started immediately.

Get Started:

1. Installation:

• Using ComfyUI Manager (Recommended):

  • Open ComfyUI Manager.
  • Go to "Install Custom Nodes".
  • Search for ComfyUI-Fooocus-V2-Expansion and install it (exists a old version fooocus-v2-expansion that should be deleted).
  • Restart ComfyUI after installation.

• Install via Git URL:

  • Navigate to your ComfyUI/custom_nodes directory.
  • Clone this repository using git:

    git clone https://github.com/PanicTitan/ComfyUI-Fooocus-V2-Expansion.git
    

  • Restart ComfyUI after installation.

Warning:

• GPT-2 Model Download: The first time you use the "Fooocus V2 Expansion" node, it will download the GPT-2 model (approximately 351MB) required for prompt expansion. This download is necessary and will only happen once. Please be patient while the model is downloaded.

2. Install Workflow Dependencies:

• ComfyUI Manager (Recommended): If you installed via ComfyUI Manager, it will likely prompt you to install missing dependencies after installation. Click "Install Missing" to automatically install any required Python packages.
• Manual Installation: If you installed manually via Git URL, you may need to manually install workflow dependencies ComfyUI-Easy-Use, ComfyUI_Comfyroll_CustomNodes and (optional) ComfyUI-Crystools.

3. Download Essential Models:

This workflow is designed to work optimally with models and LoRAs commonly used in Fooocus. You can download them here:

• Main Model (Juggernaut XL v8 - Fooocus Recommended):

  • juggernautXL_v8Rundiffusion.safetensors
  • Place this model in your ComfyUI/models/checkpoints directory.

• SDXL Offset LoRA (For enhanced style):

  • sd_xl_offset_example-lora_1.0.safetensors
  • Place this LoRA in your ComfyUI/models/loras directory.

4. Load the Workflow:

• Download the example workflow JSON file: Fooocus-ComfyUI.json
• In ComfyUI, drag and drop the Fooocus-ComfyUI.json file onto the interface.
• Ensure you have the required models and LoRA loaded correctly (CheckpointLoaderSimple and LoraLoader nodes in the workflow).

5. Run and Enjoy!

• Modify the "Positive Prompt" and "Negative Prompt" text boxes to your liking.
• Click "Queue" to generate your image with Fooocus-expanded prompts.
• Observe the "Expanded Prompt" and "Styled Prompts" nodes to see the prompt expansion in action!
