Build an AI Chatbot Instantly with OpenAI o1 using Next JS & ChatGPT API

Introduction

Creating an AI chatbot can seem like a daunting task, but with the help of OpenAI's latest model, o1, and Next.js, the process has become much more accessible. In this article, we'll walk through how to build your own AI chatbot from scratch using the OpenAI API and Next.js, and we'll even create a simple snake game using the chatbot's coding capabilities.

Step 1: Setting Up Your Development Environment

To get started, make sure you have Node.js and npm installed on your machine. You'll also need to create an OpenAI account to access their API keys. Once you have everything ready, follow these steps to set up your Next.js project:

Create a New Next.js App:

npx create-next-app my-ai-chatbot
cd my-ai-chatbot

Install OpenAI SDK: In your project directory, run:
```
npm install openai
```
Set Up Tailwind CSS (if desired): Add Tailwind CSS for styling. You can do this by following the official Tailwind CSS documentation.
Create an .env.local File: This file will store your OpenAI API key securely. Create a new file named .env.local at the root of your project and add your API key:
```
OPENAI_API_KEY=your_api_key_here
```

Step 2: Building the Chatbot

Now that we have our setup complete, we can focus on creating the chatbot.

Create an API Route for OpenAI: In the pages/api directory, create a file named chat.js. Add the following code to handle requests to the OpenAI API:

import ( Configuration, OpenAIApi ) from 'openai';

const configuration = new Configuration((
    apiKey: process.env.OPENAI_API_KEY,
));

const openai = new OpenAIApi(configuration);

export default async function handler(req, res) (
    const { message ) = req.body;
    try (
        const response = await openai.createChatCompletion({
            model: 'gpt-3.5-turbo',
            messages: [{ role: 'user', content: message )],
        });
        res.status(200).json(( reply: response.data.choices[0].message.content ));
    } catch (error) (
        console.error('Error fetching data from OpenAI API:', error);
        res.status(500).json({ error: 'Failed to fetch data' ));
    }
}

Set Up the User Interface: In pages/index.js, create a simple UI with an input field for the user message and a button to send the message. You can style it with Tailwind CSS.

import ( useState ) from 'react';

export default function Home() (
    const [message, setMessage] = useState('');
    const [chatHistory, setChatHistory] = useState([]);

    const sendMessage = async () => {
        const response = await fetch('/api/chat', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
            ),
            body: JSON.stringify(( message )),
        });
        const data = await response.json();
        setChatHistory([...chatHistory, ( user: message, bot: data.reply )]);
        setMessage('');
    };

    return (
        <div>
            <h1>AI Chatbot</h1>
            <div>
                (chatHistory.map((chat, index) => (
                    <div key={index)>
                        <p><strong>User: </strong>(chat.user)</p>
                        <p><strong>Bot: </strong>(chat.bot)</p>
                    </div>
                ))}
            </div>
            <input 
                type="text" 
                value=(message) 
                onChange=((e) => setMessage(e.target.value)) 
            />
            <button onClick=(sendMessage)>Send</button>
        </div>
    );
}

Run Your Application: In the terminal, run the following command to start your application:
```
npm run dev
```
Navigate to http://localhost:3000 and test your chatbot!

Step 3: Creating the Snake Game

One of the coolest features of the chatbot is its ability to generate code on demand. You can ask the chatbot to write a simple snake game in Python as follows:

Request the Snake Game Code: Use your chatbot interface and input the following request:

Write code for a simple snake game and make it easy for someone who knows little code to set up.

Copy and Run the Code: Once the chatbot provides you with the code, copy it into a Python file (e.g., snake_game.py) and run it. Make sure you have Python installed! Open your terminal and execute:
```
python snake_game.py
```

Conclusion

By following these steps, you've successfully built an AI chatbot using OpenAI's o1 model and Next.js. This chatbot not only interacts with users but also generates code, exemplified by creating a simple snake game. The potential of AI in software development is impressive, and with tools like OpenAI, anyone can dive into coding and create amazing applications.
