Build a GPT-3 Application Using NextJS and Replit in 20 Minutes

Why Build a GPT-3 Powered App?

In today’s fast-paced technology landscape, building applications that leverage artificial intelligence (AI) is essential. With OpenAI's GPT-3, developers can create powerful text-based applications that understand and generate human-like text. In this tutorial, we walk you through the process of building a simple GPT-3 powered application in under 20 minutes, using React and Next.js.

Getting Started with GPT-3 and Replit

We will be using Replit to host and build our application. This platform allows for real-time editing, making it perfect for quick development cycles.

1. Setting Up Replit

First, create an account at Replit. Once logged in, follow these steps:

1. Click the + sign in the top right corner to create a new project.
2. Import the GPT-3 boilerplate from GitHub by pasting this URL in the GitHub URL field.

2. Installing Dependencies

Once the project is imported, you need to add your GPT-3 API key:

1. Click the lock icon on the right side.
2. In the key field, write OPENAI_API_KEY.
3. In the value field, paste your API key.

Next, change the run command to npm run dev to start the development environment.

3. Building the Application

Your app should have a simple frontend connected to a backend powered by GPT-3. To test the setup:

1. Enter a text in the input field and click the create button.
2. Observe the generated GPT-3 output based on your input.

4. Customizing Your Application

Now that the basic application is running, we can customize it. For instance, if you want to create a summarization tool for social media posts, follow these steps:

1. Open /pages/api/openai.js and configure your prompts.
2. Edit /pages/index.js to reflect the updated functionality.

5. Testing Your Application

Use a recent article to test the summarization feature. For example, you can try summarizing a TechCrunch article about Instagram’s new ad features:

“Instagram has just announced a new feature that allows businesses to boost their Reels to turn them into ads! This is a great way to reach new audiences and get your brand story out there. Remember to check your Insights to see which ads performed the best.”

Conclusion

Congratulations on completing the GPT-3 tutorial! You've successfully set up a GPT-3 powered application in under 20 minutes.
