How to Create your own Custom ChatGPT Bot using Python

Chatbots have become an increasingly popular way for businesses to interact with their customers. They are a great tool for providing quick and efficient customer service, and they can even help generate leads and increase conversions. One of the most popular chatbot models is the OpenAI GPT-3 (Generative Pre-trained Transformer 3) model, which is a state-of-the-art natural language processing model that can generate text based on a prompt.

In this article, we'll walk you through how to create a chatbot using OpenAI GPT-3 and Python. We'll start by discussing the requirements and necessary modules needed for the project, followed by the code implementation. We'll also provide a detailed explanation of each step and offer some tips and tricks to help you get the most out of your chatbot.

So, if you're interested in creating your own chatbot using OpenAI GPT-3 and Python, then this article is for you!

Requirements:

Before starting to create the ChatGPT chatbot using Python, you need to ensure that you have the following requirements:

Python 3.x installed on your computer: Python is an interpreted, high-level, general-purpose programming language that is widely used for various purposes, including AI and machine learning. You can download Python from the official website and install it on your computer.

A text editor or Integrated Development Environment (IDE): You can use any text editor or IDE of your choice to write and execute Python code. Some popular options include PyCharm, Visual Studio Code, Sublime Text, and Notepad++.

An OpenAI API key: OpenAI is an artificial intelligence research organization that provides a platform for building and training machine learning models. To access the OpenAI GPT-3 model and use it to create the ChatGPT chatbot, you need to sign up for a free API key on the OpenAI website.

Required Modules:

Once you have these requirements set up, you can proceed to the next step of installing the necessary libraries and modules for the project.

openai: This is the OpenAI API library that allows us to connect to and use the OpenAI GPT-3 model for generating responses.

tkinter: This is a built-in Python library that provides a simple way to create graphical user interfaces (GUI) on Windows, macOS, and Linux.

To install these modules, open a terminal or command prompt and run the following command:

pip install openai tk

Once the installation is complete, we can proceed with building our ChatGPT chatbot using Python.

Code Implementation:

Firstly, we need to import the required modules into the program. Along with that, we need an OpenAI API key to access the GPT-3 model. You can sign up for a free API key on the OpenAI website.

import openai

import tkinter as tk

# Apply the API Key

openai.api_key = "YOUR_API_KEY"

Next, we're creating a function to generate a response from the OpenAI GPT-3 model. The generate_response function takes a prompt as input and returns a response generated by the GPT-3 model using the openai.Completion.create method.

# Generate a response using OpenAI GPT-3

def generate_response(prompt):

completions = openai.Completion.create(

engine="text-davinci-002",

prompt=prompt,

max_tokens=1024,

n=1,

stop=None,

temperature=0.5,

)

message = *completions.choices[0].text*

return message

The display_response function is used to display the response in a graphical user interface (GUI) using the tkinter library. The function retrieves the input text from the input field and generates a response using the generate_response function. The output is then displayed in the output field using the tkinter.Text widget.

# GUI interface

def display_response():

input_text = input_field.get()

response = generate_response(input_text)

output_field.config(state='normal')

output_field.delete(1.0, tk.END)

output_field.insert(tk.END, response)

output_field.config(state='disabled')

To create a GUI for our chatbot, we'll use the tkinter library. We create a window using the tk.Tk() method and set its title and size using the root.title() and root.geometry() methods.

# Create the main window

root = tk.Tk()

root.title("ChatGPT")

root.geometry("600x700")

Next, we create an input field using the tk.Entry widget, a submit button using the tk.Button widget, and an output field using the tk.Text widget.

# Create the input field

input_field = tk.Entry(root, font=("Arial", 14))

input_field.pack(pady=10)

# Create the submit button

submit_button = tk.Button(root, text="Submit", font=("Arial", 14), command=display_response)

submit_button.pack(pady=10)

# Create the output field

output_field = tk.Text(root, font=("Arial", 14), state='disabled')

output_field.pack(pady=10)

Finally, we start the GUI event loop using the root.mainloop() method.

# Start the GUI event loop

root.mainloop()

This completes our code implementation for building a ChatGPT chatbot using Python.

Source Code:

Here's the source code for creating a ChatGPT using Python:

import tkinter as tk

import openai

# Apply the API Key

openai.api_key = "YOUR_API_KEY"

# Generate a response using OpenAI GPT-3

def generate_response(prompt):

completions = openai.Completion.create(

engine="text-davinci-002",

prompt=prompt,

max_tokens=1024,

n=1,

stop=None,

temperature=0.5,

)

message = completions.choices[0].text

return message

# GUI interface

def display_response():

input_text = input_field.get()

response = generate_response(input_text)

output_field.config(state='normal')

output_field.delete(1.0, tk.END)

output_field.insert(tk.END, response)

output_field.config(state='disabled')

# Create the main window

root = tk.Tk()

root.title("OpenAI Chatbot")

root.geometry("600x700")

# Create the input field

input_field = tk.Entry(root, font=("Arial", 14))

input_field.pack(pady=10)

# Create the submit button

submit_button = tk.Button(root, text="Submit", font=("Arial", 14), command=display_response)

submit_button.pack(pady=10)

# Create the output field

output_field = tk.Text(root, font=("Arial", 14), state='disabled')

output_field.pack(pady=10)

# Start the GUI event loop

root.mainloop()

Note: Don't forget to replace "YOUR_API_KEY" with your own OpenAI API key.
