You may have already noticed that ChatGPT is a very basic chatbot that cannot converse with you on a personal level or cater to your specific needs.

However, imagine a highly intelligent ChatGPT chatbot that understands every aspect of your business and tirelessly handles customer inquiries 24/7.

This is now achievable by training an AI chatbot on personalized data to create a custom AI chatbot for your company.

With this exciting opportunity, we will explore and share the intriguing techniques, tools, and advice needed to build your own ChatGPT chatbot that can potentially change the way you communicate with your website visitors.

What is ChatGPT?

ChatGPT is an AI chatbot developed by OpenAI. It creates responses from the user's input by utilizing natural language processing and machine learning. Users can chat with the AI bot to create outlines, articles, stories, and summaries based on their conversations with ChatGPT.

This AI chatbot has a great benefit- it can recall prior conversations, providing a smooth engagement the next time around. Its initial use is based on GPT-3.5 tech, but to tap into GPT-4, one needs a Plus package deal.

ChatGPT remembers previous chats and allows users to ask follow-up questions, providing a quality conversation experience. Additionally, ChatGPT was trained using a large amount of internet data.

In addition to generating responses to prompts, ChatGPT also can create entry and intermediate code in any programming language. To accomplish this, simply inform ChatGPT of the programming language you require and describe the code you need. ChatGPT will analyse your input and generate code in the programming language specified. Moreover, you can refine or shorten the code generated by ChatGPT to meet your specific needs.

Another feature of ChatGPT is that it can find errors in your code blocks and explain them to you. If there is an error in your code and you cannot find it, you can use ChatGPT! Now let's move onto how you can train this smart chatbot on your own data.

How to train ChatGPT on your own data?

In order to accomplish this goal, there are essentially two methods available to you: one of them requires expertise in programming, while the other can be completed without any coding experience in just four minutes.

Before we begin, we should warn that this section requires coding experience and extensive understanding of Pyhton. If you are looking for a no-code solution, click here. Before you can train a customized ChatGPT AI chatbot, you will need to set up a software environment on your computer. Here are the steps to do so.

Step 1: Install Python & Upgrade

First and foremost, download and install Python from the official website. Make sure to check the "Add Python.exe to PATH" option during setup. Secondly, upgrade Pip, which is a package manager that allows you to install Python libraries.

This can be done through the Terminal on Windows or Command Prompt on macOS. Finally, install the essential libraries needed to train your chatbot, such as the OpenAI library, GPT Index, PyPDF2 for parsing PDF files, and PyCryptodome. These libraries are crucial for creating a Large Language Model (LLM) that can connect to your knowledge base and train your custom AI chatbot.

Step 2: Install a code editor (such as VS Code)

Firstly, download a code editor such as Notepad++ for Windows or Sublime Text for macOS and Linux if you have experience with more powerful IDEs like VS Code.

Step 3: Generate your API Key & Secret Key

Next, you will need an API key from OpenAI to train and create a chatbot that uses a custom knowledge base. To obtain this key, create an account on OpenAI or log in to your existing account, then select "View API keys" from your profile and click "Create new secret key" to generate a unique API key. It is important to save this key to a plain text file and keep it private as it is only accessible to your account. Additionally, you can create up to five API keys if necessary.

Once you have set up your software environment and obtained an OpenAI API key, it is time to train your own AI chatbot using your data.

Step 4: Select your model & create your knowledge base

You can choose to use either the "gpt-3.5" model or "gpt-4." To begin, create a folder named "docs" and add your training documents, which could be in the form of text, PDF, CSV, or SQL files, to it.

Step 5: Create the script

Next, open your code editor and save the following code as "" in the same folder as the "docs" folder. Make sure to replace the text "Your API Key" in the code with the API key you obtained from OpenAI and save the changes.

from gpt_index import SimpleDirectoryReader, GPTListIndex, GPTSimpleVectorIndex, LLMPredictor, PromptHelper
from langchain import OpenAI
import gradio as gr
import sys
import os

os.environ["OPENAI_API_KEY"] = ''

def construct_index(directory_path):
    max_input_size = 4096
    num_outputs = 512
    max_chunk_overlap = 20
    chunk_size_limit = 600

    prompt_helper = PromptHelper(max_input_size, num_outputs, max_chunk_overlap, chunk_size_limit=chunk_size_limit)

    llm_predictor = LLMPredictor(llm=OpenAI(temperature=0.7, model_name="text-davinci-003", max_tokens=num_outputs))

    documents = SimpleDirectoryReader(directory_path).load_data()

    index = GPTSimpleVectorIndex(documents, llm_predictor=llm_predictor, prompt_helper=prompt_helper)


    return index

def chatbot(input_text):
    index = GPTSimpleVectorIndex.load_from_disk('index.json')
    response = index.query(input_text, response_mode="compact")
    return response.response

iface = gr.Interface(fn=chatbot,
                     inputs=gr.inputs.Textbox(lines=7, label="Enter your text"),
                     title="My AI Chatbot")

index = construct_index("docs")

After running the code in Terminal to process your documents and create a JSON file, a local URL will be generated. Simply copy and paste this URL into your web browser to access your custom-trained ChatGPT AI chatbot.

Now, you can ask your chatbot questions and receive answers based on the data you provided.
