ComfyUI image generation

ComfyUI image generation#

ComfyUI is an open-source, node-based interface for building and running image generation workflows with diffusion models such as Stable Diffusion. Its modular graph-based design lets you construct, customize, and share complex pipelines without writing code. This page walks through installing and running ComfyUI on AMD GPUs.

Prerequisites#

Ensure your working environment is running ROCm-enabled PyTorch on a supported system. See Install PyTorch on ROCm 7.12.0 for instructions.

Install and run ComfyUI#

  1. Clone the ComfyUI repository.

    git clone https://github.com/comfyanonymous/ComfyUI.git

  2. Activate your Python virtual environment and install dependencies.

    pip install -r ComfyUI/requirements.txt

    pip install -r ComfyUI\requirements.txt

  3. Run ComfyUI.

    1. Start the ComfyUI server from the command line.

      python ComfyUI/main.py

      python ComfyUI\main.py

      This will start the server and display a prompt like:

      To see the GUI go to: http://127.0.0.1:8188

    2. Navigate to http://127.0.0.1:8188 in your web browser. You might need to replace 8188 with the appropriate port number.

    3. Search for one of the following templates and download any missing models.

      Select Template → Model Filter → SD3.5 → SD3.5 Simple

      ../_images/sd3_5-simple-card.png

      Download required models, if missing.

      Select Template → Model Filter → Chroma → Chroma1 Radiance text to image

      ../_images/chroma1-radiance-tti-card.png

      Download required models, if missing.

      ../_images/chroma1-radiance-tti-missing-models.png

    4. Click the Run button.

    The application will use your AMD GPU to convert the prompted text to an image.
