Introduction

Welcome back to Auto GPT tutorials! In this tutorial, we will walk You through the process of building your very own chatbot similar to ChatGPT using Streamlit and the OpenAI API Key. We will also cover the latest updates to Streamlit including their chat_message and chat_input features, making it easier than ever to develop interactive and user-friendly chatbots. Whether you're an experienced developer or just getting started in the AI world, this tutorial has got you covered. So let's dive in and Create your own chatbot!

Setting up the Development Environment

To start building your chatbot, you need to set up your development environment by following these steps:

Step 1: Creating the Python Virtual Environment

The first step is to create a new Python virtual environment. Open your command prompt or terminal and enter the following command:

conda create --name mychatbot python=3.11.3

This will create a new Python virtual environment named "mychatbot" with Python version 3.11.3.

Step 2: Activating the Environment

Next, activate the environment by running the following command:

conda activate mychatbot

This will activate the "mychatbot" environment and you will see the environment name in your command prompt or terminal.

Step 3: Installing Dependencies

Now, create a new file named "requirements.txt" and list all the dependencies required for your chatbot app. For example, you will need two dependencies: OpenAI and Streamlit. Save the file.

Step 4: Installing Dependencies

Install the dependencies listed in the "requirements.txt" file using the following command:

pip install -r requirements.txt

This will install all the dependencies required for your chatbot app.

Obtaining the OpenAI API Key

To integrate the OpenAI API with your chatbot, you need to obtain an API key. Here's how you can get your API key:

  1. Go to the OpenAI Dashboard and navigate to the "Profile" section.
  2. Click on "View API Key" to generate a new API key.
  3. Copy the API key and paste it in a new file named "secrets.com".
  4. In the "secrets.com" file, create a variable named "openai_api_key" and assign your API key to it.

Note: Make sure to keep your API key secure and avoid sharing it publicly.

Creating the Streamlit App

Now, let's create the main file for your chatbot app. Follow these steps:

Step 1: Open your Visual Studio Code editor and create a new file named "app.py".

Step 2: Import the necessary modules for OpenAI and Streamlit in your "app.py" file.

Step 3: Set the title of your app using the Streamlit function "st.title()". For example, you can set the title as "My Chat GPT-like Chatbot".

Step 4: Connect your app with the OpenAI API by using the variable "openai_api_key" that we defined earlier in the "secrets.com" file.

Step 5: Connect your app with the ChatGPT model. If you have access to GPT-4, you can connect with that model. Otherwise, connect with the default model GPT-3.5 Turbo.

Setting Up the Chat Interface

To create an interactive chat interface for your chatbot, follow these steps:

Step 1: Set up your session chat messaging. You can display a welcome message or any other instructions to the users.

Step 2: Add input fields for the user's chat message and the assistant's chat message. You can use the Streamlit function "st.text_input()" for this.

Step 3: Handle the chat completion response from OpenAI by using the OpenAI API function "openai.Completion.create()".

Running the Chatbot

Once you have set up the chat interface and handled the chat completion response, you are ready to run your chatbot app. Follow these steps:

Step 1: Open your terminal or command prompt and navigate to the directory where your "app.py" file is located.

Step 2: Run your app file using the following command:

streamlit run app.py
