The AI Chatbot Handbook How to Build an AI Chatbot with Redis, Python, and GPT

Ultimately we will need to persist this session data and set a timeout, but for now we just return it to the client. One of the best ways to learn how to develop full stack applications is to build projects that cover the end-to-end development process. You’ll go through designing the architecture, developing the API services, developing the user interface, and finally deploying your application. A backend API will be able to handle specific responses and requests that the chatbot will need to retrieve. The integration of the chatbot and API can be checked by sending queries and checking chatbot’s responses.

The messages sent and received within this chat session are stored with a Message class which creates a chat id on the fly using uuid4. The only data we need to provide when initializing this Message class is the message text. In Redis Insight, you will see a new mesage_channel created and a time-stamped queue filled with the messages sent from the client. This timestamped queue is important to preserve the order of the messages. We created a Producer class that is initialized with a Redis client. We use this client to add data to the stream with the add_to_stream method, which takes the data and the Redis channel name.

Here is an example of the list of messages that can be sent using the three available roles. When we use tools like ChatGPT, we always assume the role of the user, but the API lets us choose which Role we want to send to the model, for each sentence. The library will pass the InlineQuery object into the query_text function. Inside you use the answer_inline_query function which should receive inline_query_id and an array of objects (the search results).

• An untrained instance of ChatterBot starts off with no knowledge of how to communicate.
• This function will take the city name as a parameter and return the weather description of the city.
• We will not be  using any of the Machine Learning or Deep Learning Algorithms, which means our chatbot will be a decent one but not an intelligent one.
• In addition to all this, you’ll also need to think about the user interface, design and usability of your application, and much more.
• A chatbot is considered one of the best applications of natural languages processing.
• Many of these assistants are conversational, and that provides a more natural way to interact with the system.

It does not have any clue who the client is (except that it’s a unique token) and uses the message in the queue to send requests to the Huggingface inference API. Lastly, we will try to get the chat history for the clients and hopefully get a proper response. Finally, we will test the chat system by creating multiple chat sessions in Postman, connecting multiple clients in Postman, and chatting with the bot on the clients. Now, when we send a GET request to the /refresh_token endpoint with any token, the endpoint will fetch the data from the Redis database. Once we get a response, we then add the response to the cache using the add_message_to_cache method, then delete the message from the queue. Then update the main function in main.py in the worker directory, and run python main.py to see the new results in the Redis database.

The input() function is used to get user input from the command line, and the bot.get_response() method is used to get the chatbot’s response to the user’s input. The chatbot’s response is then printed to the console using the print() function. They can also be used in games to provide hints or walkthroughs. NLTK, or Natural Language Toolkit, is a leading platform for building Python programs to work with human language data. In this tutorial, we learned how to create a simple chatbot using Python, NLTK, and ChatterBot. You can further customize your chatbot by training it with specific data or integrating it with different platforms.

This way, you’ll receive notifications whenever new content is added. Now we are going to define two functions, the ones that will contain the logic of maintaining the memory of the conversation. The first thing we have to consider is that we are going to need an OpenAI payment account to use their service and that we will have to report a valid credit card. But let’s not worry, I’ve been using it a lot for development and testing, and I can assure you that the cost is negligible.
