The Dall-E tool allows your agent to create images using OpenAI’s Dall-E image generation tool.

​
Setup

You will need an OpenAI API Key which you can get from the OpenAI web site and then set the OPENAI_API_KEY environment variable to the key you just created. To use the Dall-E Tool you need to install the LangChain OpenAI integration package:
See this section for general instructions on installing LangChain packages.
npm
npm install @langchain/openai @langchain/core

/* eslint-disable no-process-env */
import { DallEAPIWrapper } from "@langchain/openai";

const tool = new DallEAPIWrapper({
  n: 1, // Default
  model: "dall-e-3", // Default
  apiKey: process.env.OPENAI_API_KEY, // Default
});

const imageURL = await tool.invoke("a painting of a cat");

console.log(imageURL);
