How to Build a AI Chatbot with GPT-3 and Django: A Step-by-Step Guide

Are you a developer interested in building AI chatbots powered by GPT-3 and Django? Look no further, as we have a step-by-step guide for you! GPT-3 is one of the most powerful natural language processing (NLP) models available today, capable of generating human-like responses to prompts. Django, on the other hand, is a popular web framework for building scalable and maintainable web applications. Together, they make for a powerful combination in building chatbots that can understand and respond to human language.

In this article, we will guide you through the process of building an AI chatbot powered by GPT-3 and Django. We will cover everything from setting up the necessary accounts and API keys to integrating GPT-3 with Django and building a functional chatbot. Whether you are a seasoned developer or just getting started with AI and web development, this guide will provide you with the necessary steps and resources to create a chatbot that can carry on a conversation with humans.


Step 1: Setting Up the Environment

Before we start building the chatbot, we need to set up our development environment. Here are the steps:

  1. Install Python and Django on your computer if you haven’t already done so.
  2. Create a new Django project using the following command in your terminal or command prompt:
    django-admin startproject myproject

  3. Create a new Django app using the following command:
    python startapp myapp

  4. Install the OpenAI API client for Python using the following command:
    pip install openai
  5. Create an account on the OpenAI website and obtain an API key.

Step 2: Integrating GPT-3 with Django

  1. In your Django project, create a new Python file called
  2. Import the openai module at the top of the file:
    import openai
  3. Set your OpenAI API key as an environment variable in your Django project’s settings file:
    import os

    os.environ["OPENAI_API_KEY"] = "YOUR_API_KEY_HERE"

  4. Initialize the OpenAI API client in your file:
openai.api_key = os.environ["OPENAI_API_KEY"]

Step 3: Building the Chatbot

Now that we have GPT-3 integrated with Django, let’s build the chatbot. Here are the steps:

1. Create a new Django view called chatbot in your file:

from django.shortcuts import render
from .gpt3 import openai

def chatbot(request):
context = {}

# Your chatbot code goes here

return render(request, 'chatbot.html', context)


2. Create a new HTML template called chatbot.html in your templates folder.

3. In the chatbot.html template, add a form with a text input field and a submit button:

<form method="post">
{% csrf_token %}
<input type="text" name="message" placeholder="Enter your message">
<button type="submit">Send</button>


4. In your chatbot view, handle the form submission and generate a response from GPT-3:

from django.shortcuts import render
from .gpt3 import openai

def chatbot(request):
context = {}

if request.method == 'POST':
message = request.POST.get('message')
response = openai.Completion.create(

context['response'] = response.choices[0].text.strip()

return render(request, 'chatbot.html', context)

5. Finally, display the chatbot’s response in the HTML template:

<div class="response">{{ response }}</div>

Step 4: Testing the Chatbot

Now that we have built the chatbot, let’s test it out. Here are the steps to test the chatbot:

  1. Run the Django development server using the command python runserver.
  2. Open your web browser and go to
  3. You should see the chatbot interface that you created earlier. Type a message in the text box and press enter.
  4. The chatbot should respond with a generated text based on the input message.
  5. You can test the chatbot with different input messages to see how it responds.

Congratulations! You have successfully built an AI chatbot with GPT-3 and Django. With this basic chatbot in place, you can further customize and enhance it based on your requirements. Some of the possible improvements that you can make include:

  • Adding a user authentication system to the chatbot, so that users can have personalized conversations with the bot.
  • Implementing a sentiment analysis system to the chatbot, so that it can detect the emotions of the users and respond accordingly.
  • Training the GPT-3 model with more data, so that it can generate more accurate and context-aware responses.
  • Adding more features to the chatbot, such as image and voice recognition, so that it can support more diverse types of inputs.

The possibilities with AI chatbots are endless, and with GPT-3, you can build powerful and intelligent chatbots that can handle complex conversations and provide personalized experiences to users.
