Introduction to Chatbot User Interface using Streamlit and OpenAI API

In this article, we will explore how to Create a chatbot user interface using Streamlit and the OpenAI API. Chatbots have become increasingly popular in various applications, and building an intuitive and interactive user interface is crucial in delivering a seamless user experience. We will dive into the components of Streamlit that are essential for creating the chatbot interface and then demonstrate how to build a chatbot using OpenAI's GPT-3.5 Turbo model. So, let's dive in and get started!

Components of Streamlit

Chat Input

One of the crucial components of building a chatbot user interface is the chat input element. It allows us to capture user input and send messages to the chatbot. The chat input element consists of a text input area where users can Type their messages and a send button to submit the message to the chatbot.

Chat Message

The chat message element is responsible for rendering the messages exchanged between the user and the chatbot. It provides styling and formatting options for the messages. Each message is displayed with a role (user or assistant) and content (the actual message).

Session State

Session state is a useful feature in Streamlit that allows us to store and access variables across different reruns of the application. It acts as a persistent dictionary, allowing us to maintain values between different interactions with the chatbot. This is especially useful when we want to remember previous conversation history or store other Relevant information.

Building the Chatbot User Interface

Importing Streamlit and Chatbot Components

To begin building our chatbot user interface, we first need to import the necessary libraries, including Streamlit and the chatbot components. Streamlit is a powerful framework for building data apps, and it provides the required functionalities for creating interactive user interfaces.

Creating the Chat Input Element

The chat input element is essential for capturing user input. It comprises a text input area where users can type their messages and a send button to submit the message. We can use the st.chat_input function provided by Streamlit to create the chat input element. The input message will be stored in a prompt variable that we can later use to send to the chatbot.

Rendering Chat Messages

Once the user sends a message, we need to render the message on the chatbot interface. The chat message element is responsible for displaying the messages. We can use the st.chat_message function to render each message with the appropriate styling and format. We loop through the list of messages and display them using st.markdown for the content and the message role.

Using Session State to Hold Variable Values

Session state is crucial when building a chatbot user interface. It allows us to maintain variables across different reruns of the application. We can use the session state as a dictionary to store and retrieve variable values. For example, we can store the conversation history between the user and the chatbot using session state.

Building the Chat GPT Clone

Now that we have covered the essential components of building a chatbot user interface, let's dive into creating a chat GPT Clone using the OpenAI API. We will use the OpenAI GPT-3.5 Turbo model API for this purpose. We will fetch the API key stored in the Streamlit secrets file and set it as the OpenAI API Key for our application.

Then, we create a chatbot by utilizing the chatbot components we discussed earlier. The user's messages are sent as Prompts to the chatbot, and the responses are displayed in real-time using the chat message container. We iterate over the conversation history stored in session state and feed it to the OpenAI API using the openai.ChatCompletion.create method. We retrieve the response tokens and display them on the chatbot interface.

Conclusion

In this article, we explored how to create a chatbot user interface using Streamlit and the OpenAI API. We discussed the essential components of Streamlit, including the chat input, chat message, and session state. We then demonstrated how to build a chatbot using the OpenAI GPT-3.5 Turbo model API. By following the steps outlined in this article, You can create your own chatbot user interface and provide an immersive experience for your users.
