# OpenAI

> Learn how to use PromptL with OpenAI

## Overview

PromptL seamlessly integrates with OpenAI's API. By default, PromptL formats prompts in the structure required by OpenAI, so you can use the output directly without additional processing.

***

## Basic Example

Here’s how to generate a response from OpenAI using PromptL:

```typescript theme={null}
import { render } from 'promptl-ai'
import OpenAI from 'openai'

const prompt = `
---
model: gpt-4o
temperature: 0.6
---

Generate a joke about {{ topic }}.
`

const { messages, config } = await render({
  prompt,
  parameters: { topic: 'chickens' },
})

const client = new OpenAI({ apiKey: YOUR_OPENAI_API_KEY })
const response = await client.chat.completions.create({
  ...config,
  messages,
})

console.log(response.choices[0].message.content)
```

***

## Key Features

1. **Default Adapter**: PromptL automatically uses the OpenAI adapter for correct formatting.
2. **Role-Based Messages**: OpenAI expects a `role` field (`system`, `user`, `assistant`) in messages, which PromptL handles for you.
3. **Configuration Pass-Through**: Configuration options (e.g., `temperature`, `model`) are passed directly to OpenAI’s API.

***

## Error Handling

When working with OpenAI, ensure you handle potential API errors gracefully:

```typescript theme={null}
try {
  const response = await client.chat.completions.create({
    ...config,
    messages,
  })
  console.log(response.choices[0].message.content)
} catch (error) {
  console.error('Error with OpenAI API:', error)
}
```
