Chatbots have become increasingly popular in recent years, with many businesses and individuals using them to provide automated customer service, personal assistance, and more. However, building a chatbot can be a daunting task, requiring a deep understanding of natural language processing and programming languages. Fortunately, with the help of OpenAI and Gradio, creating a custom chatbot has never been easier.

In this article, we will walk you through the process of building a custom chatbot using OpenAI and Gradio. We will cover two different approaches: building a chatbot from scratch using OpenAI’s GPT-3 API, and building a chatbot using Gradio’s pre-built interface.

Part 1: How To Build Chatbot In Python Using OpenAI API

To begin building your chatbot with OpenAI, you will need to have an OpenAI account and an API key. Once you have these, you can follow the steps outlined below:

OpenAI API Keys

Source Code:

import openai

openai.api_key = “####”

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(

        model=”gpt-3.5-turbo”,

        messages=messages)

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

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

    print(“\n” + reply + “\n”)

Step 1: Install the OpenAI package using pip. Open a terminal and type “pip install openai” to install the package.

Step 2: Import the OpenAI package and link your account by inserting your custom API key.

Step 3: Create a list called “messages”, which is what the OpenAI API wants to receive. You always need to send it a list as specified in the documentation.

Step 4: Set up a system message variable that takes your input, and then take the user’s answer to this and append it to the “messages” variable in exactly the format that OpenAI is asking for.

Step 5: Run a while loop that runs until you tell it to quit. This is where all the magic happens inside the loop.

Step 6: Take a new input for the user’s message, append it to the “messages” list, and start talking to the Chat GPT 3.5 Turbo API. Then, create a new variable that saves the response that you just got back from the OpenAI API.

Step 7: Append the reply that you just got from ChatGPT to the list, so once the conversation continues, it remembers what you just talked about.

Step 8: Print the reply so the user knows what ChatGPT just replied.

Part 2: How To Build Chatbot In Python Using Gradio library

Gradio is a Python library that allows you to create a custom chatbot inside a browser and even share it with a friend. To build a chatbot with Gradio, you will need to follow these steps:

Source Code:

import openai

import gradio

openai.api_key = “####”

messages = [{“role”: “system”, “content”: “You are a financial experts that specializes in real estate investment and negotiation”}]

def CustomChatGPT(user_input):

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

    response = openai.ChatCompletion.create(

        model = “gpt-3.5-turbo”,

        messages = messages

    )

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

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

    return ChatGPT_reply

demo = gradio.Interface(fn=CustomChatGPT, inputs = “text”, outputs = “text”, title = “Real Estate Pro”)

demo.launch(share=True)

Step 1: Install the Gradio package using pip. Open a terminal and type “pip install gradio” to install the package.

Step 2: Copy and paste your OpenAI API key into the appropriate section in the code.

Step 3: Customize your chatbot by editing the “messages” variable. In the example given in the code, the chatbot is set up as a psychologist.

Step 4: Define a function that will consult the ChatGPT API using the user inputs that the function is based upon to generate a prompt reply, which it will feed back into Gradio.

Step 5: Use Gradio’s pre-built interface to set up the simplest implementation of your chatbot.
