======

LangChain.js supports Cohere LLMs. Here's an example:

You'll first need to install the [`@langchain/cohere`](https://www.npmjs.com/package/@langchain/cohere) package.

tip

See [this section for general instructions on installing integration packages](/v0.2/docs/how_to/installation#installing-integration-packages).

*   npm
*   Yarn
*   pnpm

    npm install @langchain/cohere

    yarn add @langchain/cohere

    pnpm add @langchain/cohere

    import { Cohere } from "@langchain/cohere";const model = new Cohere({  maxTokens: 20,  apiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.COHERE_API_KEY});const res = await model.invoke(  "What would be a good company name a company that makes colorful socks?");console.log({ res });
