Cloudflare Workers AI
=====================

info

Workers AI is currently in Open Beta and is not recommended for production data and traffic, and limits + access are subject to change

Workers AI allows you to run machine learning models, on the Cloudflare network, from your own code.

Usage[​](#usage "Direct link to Usage")
---------------------------------------

You'll first need to install the LangChain Cloudflare integration 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/cloudflare

    yarn add @langchain/cloudflare

    pnpm add @langchain/cloudflare

    import { CloudflareWorkersAI } from "@langchain/cloudflare";const model = new CloudflareWorkersAI({  model: "@cf/meta/llama-2-7b-chat-int8", // Default value  cloudflareAccountId: process.env.CLOUDFLARE_ACCOUNT_ID,  cloudflareApiToken: process.env.CLOUDFLARE_API_TOKEN,  // Pass a custom base URL to use Cloudflare AI Gateway  // baseUrl: `https://gateway.ai.cloudflare.com/v1/{YOUR_ACCOUNT_ID}/{GATEWAY_NAME}/workers-ai/`,});const response = await model.invoke(  `Translate "I love programming" into German.`);console.log(response);/* Here are a few options:1. "Ich liebe Programmieren" - This is the most common way to say "I love programming" in German. "Liebe" means "love" in German, and "Programmieren" means "programming".2. "Programmieren macht mir Spaß" - This means "Programming makes me happy". This is a more casual way to express your love for programming in German.3. "Ich bin ein großer Fan von Programmieren" - This means "I'm a big fan of programming". This is a more formal way to express your love for programming in German.4. "Programmieren ist mein Hobby" - This means "Programming is my hobby". This is a more casual way to express your love for programming in German.5. "Ich liebe es, Programme zu schreiben" - This means "I love writing programs". This is a more formal way to express your love for programming in German.*/const stream = await model.stream(  `Translate "I love programming" into German.`);for await (const chunk of stream) {  console.log(chunk);}/*  Here  are  a  few  options  :  1  .  "  I  ch  lie  be  Program  ...*/
