Usage Method
Workflow Examples
This API node currently supports two workflows:
- Text to Image
- Inpainting
Image to Image workflow is not supported
Text to Image Example
The image below contains a simple text-to-image workflow. Please download the corresponding image and drag it into ComfyUI to load the workflow.
The corresponding example is very simple
You only need to load the OpenAI DALL·E 2 node, input the description of the image you want to generate in the prompt node, connect a Save Image node, and then run the workflow.
Inpainting Workflow
DALL·E 2 supports image editing functionality, allowing you to use a mask to specify the area to be replaced. Below is a simple inpainting workflow example:
1. Workflow File Download
Download the image below and drag it into ComfyUI to load the corresponding workflow.
We will use the image below as input:
2. Workflow File Usage Instructions
Since this workflow is relatively simple, if you want to manually implement the corresponding workflow yourself, you can follow the steps below:
- Use the
Load Imagenode to load the image - Right-click on the load image node and select
MaskEditor - In the mask editor, use the brush to draw the area you want to redraw
- Connect the loaded image to the
imageinput of the OpenAI DALL·E 2 node - Connect the mask to the
maskinput of the OpenAI DALL·E 2 node - Edit the prompt in the
promptnode - Run the workflow
Notes
- If you want to use the image editing functionality, you must provide both an image and a mask (both are required)
- The mask and image must be the same size
- When inputting large images, the node will automatically resize the image to an appropriate size
- The URLs returned by the API are valid for a short period, please save the results promptly
- Each generation consumes credits, charged according to image size and quantity
