Chatbots with Generative AI Models

Welcome to the future of chatbots! Imagine talking to a virtual assistant that feels almost human. In this project, we dive deep into building chatbots powered by cutting-edge generative AI models like GPT-3.5-turbo and GPT-4. These chatbots can create meaningful, real-time conversations that feel natural and engaging.

Ready to explore how these bots can transform how we interact online? Let's get started!

Project Overview

This project aims at the development of the latest generative AI-powered chatbots. These chatbots are capable of having conversations with a user like a real human assistant using GPT-3.5-turbo and GPT-4. In this project, you will learn everything from the code setup to using OpenAI API for creating the chatbot.

You'll learn:

  • How to prepare the code and execute it either on one’s own machine or by using online servers such as Colab.
  • The crucial Python libraries for creating AI-powered bots.
  • How to use AI technology to provide intelligent responsive feedback.

By the end, you will not just learn the workings of these bots but you will also know how they can be applied practically in sectors like corporate customer care, education, and others.

Prerequisites

Let’s ensure you're all set before we start this exciting process of creating chatbots! Do not worry, it is all easy, but having some prerequisites in preparation will help everything to work efficiently.

  • Basic Knowledge of Python Programming: You do not have to be a coding master, but it would be better if you could be able to write python commands.
  • Understanding of Concept Of APIs: Understanding of how API’s work to communicate with AI Models.
  • OpenAI API Key: We need an API key to connect with GPT-3.5 and GPT-4. But it is easy to get.
  • Google Colab or Local Python Setup: This project is based on Google Colab. This means you are able to code in your internet browser. You can also set up the environment locally.

Approach

In this project, we take a simple yet very effective method to build an AI chatbot. Then, we dive into generative AI models like GPT-3.5 turbo and GPT-4 that power your natural conversations. Then, we set up the coding environment on Google Colab for the browser-based coding. We then set up the OpenAI API. It will allow our chatbot to respond back smartly and humanly.

Now that it's set up and ready to roll, we start building the chatbot by writing code for how it will interact with users and respond to human input. Last, we test the chatbot, iterating on its response to make sure it sounds like a real conversation.

Workflow and Methodology

Workflow

  • Prepare the Environment: All the required libraries to run the program should be installed. Also, configure the OpenAI API credentials necessary for accessing the GPT models.
  • Prepare the Bot: Write the code to get started with the chatbot. So that the bot will greet and take user inputs and give responses using GPT-3.5-turbo or GPT-4.
  • Generate Response: A user asks a question to the chatbot. Then the chatbot processes it. Then generate responses using models.
  • Conversation loops: The loop makes the bot go on continuous conversations until the user ends the conversation.
  • Test: Chat with the bot, asking different questions. Adjust the code to generate a correct response. Experiment with parameters such as temperature and max tokens.
  • Deployment: If everything is working as expected. Then it is time to make the bot available for use, allowing interactions with real users!

Methodology

The methodology of this project is to build an AI chatbot as simple and effective as possible. Initially, we import and install the needed Python libraries such as OpenAi. So that we’ll be able to take advantage of GPT-3.5-turbo and GPT-4 models. We next set up the OpenAI API, plugging in the API key. It provides us with access to the chatbot’s language abilities.

After all that is done, we create a function that takes user inputs and passes them to the GPT model via the OpenAI API. We take inputs from people who are using the model and process that through the model to generate human-like responses that are later displayed back to the user. It will keep on chatting with the user in a loop until the user wants to quit.

Finally, we evaluate our chatbot’s performance by playing with parameters such as the max length of the response (max tokens), and creativity (temperature) to find a good balance between informative and natural-sounding responses.

Data Collection and Preparation

Data Collection Workflow

The objective of this project is to obtain data interactively as the users engage. Here is how it works:

  • User Input: Users give their questions to the chatbot during a live discussion.
  • Send Input to GPT Models: Each input is routed directly to the GPT-3.5-turbo or GPT-4 models via the OpenAI API.
  • No Data Storage for Training: Since the generative AI models are employed in the project, there is no need to gather or keep the data for retraining purposes.

Data preparation workflow

This project focuses mainly on interacting in real time with GPT models hence not much data preparation is needed. The chatbot keeps tracking throughout the talk what the users say. GPT models that we use in this project have already been trained, so it doesn’t require us to clean and organize data by hand.

Code Explanation

STEP 1:

Import and install necessary libraries

With this command, we install OpenAI library which enables us to work with the GPT models. After installation, this library can be used for the purpose of sending requests to OpenAI API and receiving responses generated by models.

!pip install openai

This snippet of code imports the necessary libraries for the project. In this case, os lets you communicate with your environment, while openai provides access to the OpenAI API. To ease the process of using AI models and API, the OpenAI class is imported.
import os
import openai
from openai import OpenAI

STEP 2:

Configure API key

This segment of code initializes your OpenAI API key, which allows you to use GPT models including GPT-3.5-turbo and GPT-4 without any restrictions.
To obtain your API key, you can do the following:

  • Create an Account on OpenAI: Visit the OpenAI website first to create an account.
  • Get Your API Key: After you log into the account you created, go to the dashboard. On the API section there, you can create new API keys. You must copy it immediately after creating the key since it is the only time you will get to see that key again.
  • Make Openai Key as Environment Variable: For safety reasons, Most people tend to use an environment variable to store their OpenAI API keys which this code does by using os.environ.get(“OPENAI_API_KEY”). You can do this in your terminal or environment manager.

In the code (like in the client object), you may choose to assign your API key directly but it is better to conceal the api key by saving it in an environment variable to prevent it from being accessed in public domain code repositories

# Replace with your OpenAI API key
openai.api_key = os.environ.get("OPENAI_API_KEY")
client = OpenAI(api_key='sk-Tubj3Vw0akvUJBa2lbMjTBlbkFJvpnY3gQZomOyBfA1Kf57')

STEP 3:

Generating Real-Time API Responses with GPT-3.5-turbo

The generate_api_validation_tests function is used to optimize chatbot conversation using the GTP-3.5-turbo model. The model accepts the input and generates output based on its system message “You are a helpful Chatbot assistant,” which serves as a guideline for what the system should do. Max_tokens is used to limit the size of the response returned. Temperature is used to determine the creativity and predictability of the generated response. Finally, the function displays the generated response to the user.

def generate_api_validation_tests(response, max_tokens=20, temperature=0.7):
    response = client.chat.completions.create(
        model = "gpt-3.5-turbo",
        messages=[
            {"role": "system", "content": "You are a helpful Chatbot assistant ."},
            {"role": "user", "content": response}  # This line will use the provided response
        ],
        max_tokens=max_tokens,
        temperature=temperature
    )
    return response.choices[0].message.content

Conversation in loops for GPT-3.5-turbo

This section of the code initiates an interactive loop, allowing both the chatbot and the user to engage in a continuous dialogue. It begins by prompting the user for a query through the input() command. Next, the user’s query is sent to the generate_api_validation_tests function for processing. This function issues a command to either GPT-4 or GPT-3.5-turbo, which generates a response. The response is then printed out to display the answer to the user.

The bot asks whether the user would like to continue the conversation after each response. If the response is yes, the loop continues. This allows more questions and answers. If the user provides any other input, the loop terminates, and the conversation ends.

# Start loop
while True:
    # Ask user for a question
    user_question = input("User: ")
    # Generate response based on user's question
    api_validation_tests = generate_api_validation_tests(user_question, max_tokens=20, temperature=0.5)
    print("Chatbot: ", api_validation_tests)
    # Ask the user if they want to continue
    continue_response = input("Continue conversation? (yes/no): ")
    if continue_response.lower() != "yes":
        break  # Exit the loop if the user does not want to continue

Generating Real-Time API Responses with GPT-4

This generate_api_validation_tests function also generates responses but makes use of a much newer model (GPT-4). It works by accepting a user question (response), directing it to GPT-4 through the OpenAI API, and retrieving a response. The system prompt says, “You are helpful Chatbot Assistant” which guides the AI on how to conduct itself. The user message is whatever the user wants to know or request and it is sent to the chatbot that has to provide a reply. The max_tokens parameters set limitations on the response length while temperature enhances the creativity in responses. The function returns the output from the chatbot and thus, makes this ready to be used for conversations with the users in real time. It is a more efficient way to deal with user queries!

def generate_api_validation_tests(response, max_tokens=20, temperature=0.7):
    response = client.chat.completions.create(
        model="gpt-4",
        messages=[
            {"role": "system", "content": "You are a helpful Chatbot assistant ."},
            {"role": "user", "content": response}  # This line will use the provided response
        ],
        max_tokens=max_tokens,
        temperature=temperature
    )
    return response.choices[0].message.content

STEP 4:

Conversation in loops for GPT-4

# Start loop
while True:
    # Ask user for a question
    user_question = input("User: ")
    # Generate response based on user's question
    api_validation_tests = generate_api_validation_tests(user_question, max_tokens=20, temperature=0.5)
    print("Chatbot: ", api_validation_tests)
    # Ask the user if they want to continue
    continue_response = input("Continue conversation? (yes/no): ")
    if continue_response.lower() != "yes":
        break  # Exit the loop if the user does not want to continue

This project illustrates how AI can make some human tasks more convenient and shows the advancement of technology interfacing with individuals more interestingly. While this technology in a way is still in its budding stage. Hence such chatbots will be more prominent in day-to-day life activities.

This project demonstrates how GPT-3.5-turbo and GPT-4 may be used to easily and powerfully create interactive chatbots. We created a chatbot that can converse with people in real-time and respond intelligently and naturally by using the OpenAI API. This chatbot can be customized to fill a range of roles, including customer service, education, and entertainment. The study demonstrates how artificial intelligence (AI) may improve human-human relationships and emphasizes how technology is constantly evolving to create more immersive and realistic experiences. These kinds of chatbots will become more and more important in our daily lives as AI develops.

Challenges and Solutions

While the process of building this chatbot is simple enough, there are some hurdles that you are likely to experience.

Challenge: The OpenAI API Key is not provided
Solution: Remember to create an account on the OpenAI website and obtain an API key from it. In case you do not know, it can be added either by creating environment variables or straight in the code.

Challenge: API rate limits
Solution: For OpenAI, there are also some rate limitations on the number of requests you are allowed to send. If you hit the limit, make sure to upgrade the plan or try to reduce the number of requests.

Challenge: Error in Libraries Installation
Solution: Some errors may occur during installation or importing libraries. Try to restart the colab if an error occurs or run pip install openai again. Besides that, don't forget to check your network connection.

Challenge: Long response time problem
Solution: If the undesirable delay is on the part of the chatbot, adjust the parameters max_tokens and temperature to make the response less in-depth and less intricate. That will assist in this aspect.

FAQ

Question 1: Where do I obtain an OpenAI API key, and is it free?
Answer: To achieve this we use an API key, which we can obtain by signing up with the OpenAI platform. You’ll have to pay to switch to a paid plan if you need more than their free tier. But the free tier is great for most.

Question 2: Can I customize the response?
Answer: Yes! You can customize the chatbot's responses by changing parameters like temperature for creativity or by changing the system message (e.g. 'You're a good assistant').

Question 3: So what if the chatbot’s responses are too long or too short?
Answer: You can also control the length of the chatbot’s replies by the max_tokens parameter. This means longer responses or shorter replies.

Question 4: Is this chatbot good enough for real-world use?
Answer: Absolutely! This chatbot can be integrated into Customer service platforms, and educational tools, and be integrated into virtual assistants.
