OpenAIDalle2 - ComfyUI Built-in Node Documentation

Complete documentation for the OpenAIDalle2 node in ComfyUI. Learn its inputs, outputs, parameters and usage.

Generates images synchronously via OpenAI’s DALL·E 2 endpoint.

How It Works

This node connects to OpenAI’s DALL·E 2 API to create images based on text descriptions. When you provide a text prompt, the node sends it to OpenAI’s servers which generate corresponding images and return them to ComfyUI. The node can operate in two modes: standard image generation using just a text prompt, or image editing mode when both an image and mask are provided. In editing mode, it uses the mask to determine which parts of the original image should be modified while keeping other areas unchanged.
