The AI called ChatGPT, an innovation by the company OpenAI, is a chatbot language model that generates conversational text. This specialized GPT-3.5 and 4 version, leverages deep learning techniques for human-like responses in natural language processing tasks.

ChatGPT’s acquired proficiency through learning and training which extends across a wide spectrum of applications, encompassing chatbot interactions, email correspondence, and engagements on social media.

Simple Steps To Create A Chatbot With ChatGPT API

Creating a chatbot using the ChatGPT API is one way to add interactive conversations to your applications. Listed below are certain steps that are required in order to embed a chatbot:

Generate An API Key On ChatGPT

Begin by ensuring all necessary tools and credentials are in place. An API key is essential for ChatGPT API access. An API key is a code or token that serves as a passkey, allowing access to a specific application or service’s API. 

To use the ChatGPT API, one needs to register for an API key. This can be done by visiting the OpenAI website and following the instructions.

  • Sign in to an OpenAI account on the OpenAI website.
  • Click the “View API Key” button in the top right corner of the page.
  • Click the “Create an API Key” button to generate a new API key.

Get Your API Key

Acquire the necessary API key from OpenAI following the steps laid out above in “Set Up The Development Environment”. This key is crucial for connecting to the ChatGPT API. Create an OpenAI account and follow the steps outlined in their tutorial to obtain your API key.

Prepare The Code

Open the folder and locate a Python script within it. Paste the API key in the designated section. This script serves as the foundation for the chatbot application.

Script to paste in Visual Studio Code :

import openai

openai.api_key = “xxxx”

messages = []

system_msg = input(“What type of chatbot would you like to create?n)

messages.append({“role”: “system”, “content”: system_msg})

print(“Your new assistant is ready!”)

while input != “quit()”:

   message = input()

   messages.append({“role”: “user”, “content”: message})

   response = openai.ChatCompletion.create(



   reply = response[“choices”][0][“message”][“content”]

   messages.append({“role”: “assistant”, “content”: reply})

   print(n + reply + n)

Run The Application 

After adding the API key and making any necessary code adjustments, the application can be executed. Utilize the code editor’s play button or run it from the terminal. The script is designed to communicate with the ChatGPT API.

Here are the steps to run the Python script in Visual Studio Code:

  1. Open the Python script required for execution in Visual Studio Code.
  2. Ensure that the Python extension is installed in Visual Studio Code. If it’s not installed, you can do so from the Visual Studio Code marketplace.
  3. Within the Python script, position the cursor where the code execution should start.
  4. To execute the code, you have multiple options:
    • Right-click within the script editor and select “Run Python File in Terminal.” 
    • Use the keyboard shortcut Ctrl + Enter (Cmd + Enter on Mac) to execute the code at the cursor.
    • On Microsoft Windows, you can use the keyboard shortcut Ctrl + Enter to execute the code at the cursor.
  5. Visual Studio Code will proceed to execute the Python code in the terminal pane at the bottom.

Try Out The Chatbot 

Once the chatbot is launched, one can interact with the chatbot. It will respond to the prompts given to it. 


Extend The Chatbot

To create a more customized chatbot that allows for back-and-forth interactions.This script sets up a system message and initializes a conversation with the custom chatbot, which keeps track of the conversation history.

Deploy A Web-Based Chatbot

If interested in sharing the chatbot with others, customizing the chatbot is made easy through changing variables like title and profession.

Customize And Share

Now the chatbot can be customized according to needs and interests. The chatbot’s title and profession can be adjusted to tailor its responses and utility. Share the web-based chatbot with friends or anyone who might find it valuable.
