Using OpenAI API with the AI SDK

The AI SDK provides a streamlined way to integrate OpenAI's powerful models into your applications. It abstracts away the complexities of working directly with the OpenAI API, making it easier to build AI-powered features 12.

Getting Started

First, you'll need to install the AI SDK and the OpenAI integration package:

Setting Up Your OpenAI API Key

Before using OpenAI's models, you need to obtain an API key:

1. Log into your OpenAI Dashboard
2. Navigate to API keys section
3. Click "Create new secret key"
4. Copy the generated API key securely 34

Add the API key to your environment variables:

Basic Usage

Here's a simple example of generating text with OpenAI's models using the AI SDK:
