description: "This example will show you how to generate an image using DALL·E 3 and text using GPT-4o with Trigger.dev."
---

## Overview

This example demonstrates how to use Trigger.dev to make reliable calls to AI APIs, specifically OpenAI's GPT-4o and DALL-E 3. It showcases automatic retrying with a maximum of 3 attempts, built-in error handling to avoid timeouts, and the ability to trace and monitor API calls.

## Task code

```ts trigger/generateContent.ts
import { task } from "@trigger.dev/sdk";
import OpenAI from "openai";

const openai = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
});

type Payload = {
  theme: string;
  description: string;
};

export const generateContent = task({
  id: "generate-content",
  retry: {
    maxAttempts: 3, // Retry up to 3 times
  },
  run: async ({ theme, description }: Payload) => {
    // Generate text
    const textResult = await openai.chat.completions.create({
      model: "gpt-4o",
      messages: generateTextPrompt(theme, description),
    });

    if (!textResult.choices[0]) {
      throw new Error("No content, retrying…");
    }

    // Generate image
    const imageResult = await openai.images.generate({
      model: "dall-e-3",
      prompt: generateImagePrompt(theme, description),
    });

    if (!imageResult.data[0]) {
      throw new Error("No image, retrying…");
    }

    return {
      text: textResult.choices[0],
      image: imageResult.data[0].url,
    };
  },
});

function generateTextPrompt(theme: string, description: string): any {
  return `Theme: ${theme}\n\nDescription: ${description}`;
}

function generateImagePrompt(theme: string, description: string): any {
  return `Theme: ${theme}\n\nDescription: ${description}`;
}
```

## Testing your task

To test this task in the dashboard, you can use the following payload:

```json
{
  "theme": "A beautiful sunset",
  "description": "A sunset over the ocean with a tiny yacht in the distance."
}
```
