How use the GPT OpenAI API in a Django application

OpenAI GPT is a state-of-the-art natural language processing technology that can generate human-like text from a given prompt. Integrating GPT into a Django web application can enable you to add advanced language processing capabilities to your project.
In this article, we will guide you through the process of setting up OpenAI GPT in a Django web application. We will cover the steps required to obtain an API key, authenticate requests to the OpenAI API, and interact with the GPT model to generate text. By the end of this article, you should have a working Django web application that can generate text using OpenAI GPT.
Note that some prior knowledge of Django and Python is assumed, but we will do our best to explain the process in a beginner-friendly way. Let's get started!

Get an OpenAI API key

You will need to sign up for an OpenAI account and obtain an API key to access their GPT models. Follow the instructions on the OpenAI website to create an account and get an API key.

Install the openai package:

You will need to install the openai package to interact with the GPT API.

pip install openai

Set up the API key

In order to access the OpenAI platform, you will need to log in first by visiting the following website: https://platform.openai.com/login/.

First, click on your personal profile located in the top-right corner of the OpenAI platform.

In the dropdown menu that appears, select "View API Keys" to access your API key settings.

Once you're on the API keys page, click the "Create New Secret Key" button to generate a new API key that you can use to interact with the OpenAI API.

Be sure to copy and save the newly generated API key in a secure location for future use, as it will not be displayed again.

Set up the key in your Django application

You can do this by adding the following line to your settings.py file

OPENAI_API_KEY = "YOUR_OPENAI_API_KEY"

Use the API to generate text

You can use the openai.Completion.create() method to generate text from the GPT API. For example, to generate a paragraph of text, you could use the following code

import openai
from django.shortcuts import render
from django.http import JsonResponse

openai.api_key = settings.OPENAI_API_KEY

def generate_response(request):
    prompt = request.POST.get('prompt')
    response = openai.Completion.create(
        engine="davinci",
        prompt=prompt,
        max_tokens=1024,
        n=1,
        stop=None,
        temperature=0.7,
)
    return JsonResponse({'response': response.choices[0].text})

then add the view to your urls.py

add the "generate_response" view to your URLs like this

from django.urls import path
from .views import generate_response
urlpatterns = [
# ...other URL patterns...
path('generate-response/', generate_response),
]

then Save the URLs file and start/restart your Django development server.
