This is a custom node for ComfyUI that allows you to use the Luma AI API directly in ComfyUI. Luma AI API is based on top of Dream Machine, which is a complete suite of models for image and video generation. For more information, see Luma AI API Documentation.

Requirements

Before using this node, you need to have an LumaAI API key. Get one here. If you want to use images as input, you will need to host them. As a suggestion, you can use ImgBB to host your images.

Installation

Installing manually

  1. Navigate to the ComfyUI/custom_nodes directory.

  2. Clone this repository:

    git clone https://github.com/lumalabs/ComfyUI-LumaAI-API.git

    The path should be ComfyUI/custom_nodes/ComfyUI-LumaAI-API/*, where * represents all the files in this repo.

  3. Install the dependencies:

  • If you are using Windows (ComfyUI portable) run: .\python_embeded\python.exe -m pip install -r ComfyUI\custom_nodes\ComfyUI-LumaAI-API\requirements.txt
  • If you are using Linux or MacOS, run: cd ComfyUI-LumaAI-API && pip install -r requirements.txt to install the dependencies.

  1. If you don't want to expose your Luma API key, you can add it to the config.ini file and keep it empty in the node.

  2. Start ComfyUI and enjoy using the LumaAI API node!

Installing with ComfyUI-Manager

  1. Open ComfyUI-Manager and install the LumaAI API node (ComfyUI-LumaAI-API).

Installing with Comfy Registry

  1. Run comfy node registry-install comfyui-lumaai-api to install the node.

Nodes

Most of the nodes allow you to save locally the output video. If you keep the default filename (empty string), the video will be saved in the outputs folder using the generation_id as the name.

For images, the node will always save the image locally, but you can set the filename to save it with a custom name.

LumaAIClient

This node is used to create a LumaAI client.

LumaText2Video

This node is used to generate a video from a text prompt.

LumaImage2Video

This node is used to generate a video from an image. The image can be used as the first or last frame.

LumaInterpolateGenerations

LumaExtendGeneration

This node is used to extend a generation. You can choose to extend before or after the generation.

LumaPreviewVideo

This node is used to preview a video. The video is resized to 768px to look better on ComfyUI.
