    How to Install

    1. Go to Retro Diffusion and sign up for an account if you don't have one.
    2. Create an API key from the developer tools.
    3. In the root folder of your ComfyUI installation, create a .env file if it doesn't exist already.
    4. Add the following to your .env:
    RD_API_KEY=your-key
    1. Clone this repository into your ComfyUI/custom_nodes folder.
    2. Start ComfyUI.

    Now you can create a Retro Diffusion API Node in your workflows.

    Features

    • Text-to-image and image-to-image
    • Outputs credit cost of the image and your remaining credits too
    • Supports RD_Fast, RD_PLUS, and Animation styles as of the latest commit

    More info on the Retro Diffusion API itself can be found here - https://github.com/Retro-Diffusion/api-examples

    Notes

    • RD_PLUS and Animation styles are more expensive to generate than RD_Fast.
    • Check the console if you get any errors, and feel free to create an issue.
    • There is an upload size limit for image-to-image, so keep that in mind (don't send large images as input).
