# Automatic Tool Call Roundtrips with Vercel AI SDK

A Next.js chatbot using the Vercel AI SDK's streamText function to automatically handle multiple tool call roundtrips.

# Automatic Multiple Tool Steps Preview

This example demonstrates how to use the [Vercel AI SDK](https://sdk.vercel.ai/docs) with [Next.js](https://nextjs.org/) and the `streamText` function to automatically handle multiple tool steps.

## Deploy your own

[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Fvercel-labs%2Fai-sdk-preview-roundtrips&env=OPENAI_API_KEY&envDescription=API%20keys%20needed%20for%20application&envLink=platform.openai.com)

## How to use

Run [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init), [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/), or [pnpm](https://pnpm.io) to bootstrap the example:

```bash
npx create-next-app --example https://github.com/vercel-labs/ai-sdk-preview-roundtrips ai-sdk-preview-roundtrips-example
```

```bash
yarn create next-app --example https://github.com/vercel-labs/ai-sdk-preview-roundtrips ai-sdk-preview-roundtrips-example
```

```bash
pnpm create next-app --example https://github.com/vercel-labs/ai-sdk-preview-roundtrips ai-sdk-preview-roundtrips-example
```

To run the example locally you need to:

1. Sign up for accounts with the AI providers you want to use (e.g., OpenAI, Anthropic).
2. Obtain API keys for each provider.
3. Set the required environment variables as shown in the `.env.example` file, but in a new file called `.env`.
4. `npm install` to install the required dependencies.
5. `npm run dev` to launch the development server.
