How to create a custom AI chatbot with Python
Asking the same questions to the original Mistral model and the versions that we fine-tuned to power our chatbots produced wildly different answers. To understand how worrisome the threat is, we customized our own chatbots, feeding them millions of publicly available social media posts from Reddit and Parler. AI SDK requires no sign-in to use, and you can compare multiple models at the same time.
So we can have some simple logic on the frontend to redirect the user to generate a new token if an error response is generated while trying to start a chat. Next, in Postman, when you send a POST request to create a new token, you will get a structured response like the one below. You can also check Redis Insight to see your chat data stored with the token as a JSON key and the data as a value.
To set up the project structure, create a folder namedfullstack-ai-chatbot. Then create two folders within the project called client and server. The server will hold the code for the backend, while the client will hold the code for the frontend. By following these steps, you’ll have a functional Python AI chatbot to integrate into a web application. This lays the foundation for more complex and customized chatbots, where your imagination is the limit.
Next, to run our newly created Producer, update chat.py and the WebSocket /chat endpoint like below. Now that we have our worker environment setup, we can create a producer on the web server and a consumer on the worker. We create a Redis object and initialize the required parameters from the environment variables.
Step 5: Train Your Chatbot on Custom Data and Start Chatting
In real life, developing an intelligent, human-like chatbot requires a much more complex code with multiple technologies. However, Python provides all the capabilities to manage such projects. The success depends mainly on the talent and skills of the development team. Currently, a talent shortage is the main thing hampering the adoption of AI-based chatbots worldwide.
The three primary types of chatbots are rule-based, self-learning, and hybrid. If you’re not interested in houseplants, then pick your own chatbot idea with unique data to use for training. Repeat the process that you learned in this tutorial, but clean and use your own data for training. Your chatbot has increased its range of responses based on the training data that you fed to it. As you might notice when you interact with your chatbot, the responses don’t always make a lot of sense.
The client listening to the response_channel immediately sends the response to the client once it receives a response with its token. Finally, we need to update the /refresh_token endpoint to get the chat history from the Redis database using our Cache class. Next, run python main.py a couple of times, changing the human message and id as desired with each run. You should have a full conversation input and output with the model. Next, we need to update the main function to add new messages to the cache, read the previous 4 messages from the cache, and then make an API call to the model using the query method. It’ll have a payload consisting of a composite string of the last 4 messages.

Our next order of business is to create a vocabulary and load
query/response sentence pairs into memory. Artificial Intelligence is rapidly creeping into the workflow of many businesses across various industries and functions. Open Anaconda Navigator and Launch vs-code or PyCharm as per your compatibility. Now to create a virtual Environment write the following code on the terminal. We’ll later use this as the context provided to the LLM when chatting. Our example code will use Apify’s Website Content Crawler to scrape the selected website and store it in a local vector database.
Let’s have a quick recap as to what we have achieved with our chat system. The chat client creates a token for each chat session with a client. Python AI chatbots are essentially programs designed to simulate human-like conversation using Natural Language Processing (NLP) and Machine Learning.
Run Model¶
Then we will include the router by literally calling an include_router method on the initialized FastAPI class and passing chat as the argument. Use Flask to create a web interface for your chatbot, allowing users to interact with it through a browser. Use the ChatterBotCorpusTrainer to train your chatbot using an English language corpus. You can use hybrid chatbots to reduce abandoned carts on your website.
DigitalOcean makes it simple to launch in the cloud and scale up as you grow — whether you’re running one virtual machine or ten thousand. If you’re not sure which to choose, learn more about installing packages. Am into the study of computer science, and much interested in AI & Machine learning.
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. In my experience, building chatbots is as much an art as it is a science.
Create formatted data file¶
We will use Redis JSON to store the chat data and also use Redis Streams for handling the real-time communication with the huggingface inference API. As we continue on this journey there may be areas where improvements can be made such as adding new features or exploring alternative methods of implementation. Keeping track of these features will allow us to stay ahead of the game when it comes to creating better applications for our users. Once you’ve written out the code for your bot, it’s time to start debugging and testing it. Having completed all of that, you now have a chatbot capable of telling a user conversationally what the weather is in a city.
However, our chatbot is still not very intelligent in terms of responding to anything that is not predetermined or preset. Artificially intelligent ai chatbots, as the name suggests, are designed to mimic human-like traits and responses. NLP (Natural Language Processing) plays a significant role in enabling these chatbots to understand the nuances and subtleties of human conversation. AI chatbots find applications in various platforms, including automated chat support and virtual assistants designed to assist with tasks like recommending songs or restaurants.
Note that we are using the same hard-coded token to add to the cache and get from the cache, temporarily just to test this out. You can always tune the number of messages in the history you want to extract, but I think 4 messages is a pretty good number for a demo. Note that to access the message array, we need to provide .messages as an argument to the Path. If your message data has a different/nested structure, just provide the path to the array you want to append the new data to. Now when you try to connect to the /chat endpoint in Postman, you will get a 403 error.
This is why complex large applications require a multifunctional development team collaborating to build the app. In addition to all this, you’ll also need to think about the user interface, design and usability of your https://chat.openai.com/ application, and much more. To learn more about data science using Python, please refer to the following guides. When it gets a response, the response is added to a response channel and the chat history is updated.
This provides both bots AI and chat handler and also
allows easy integration of REST API’s and python function calls which
makes it unique and more powerful in functionality. This AI provides
numerous features like learn, memory, conditional switch, topic-based
conversation handling, etc. For computers, understanding numbers is easier than understanding words and speech. When the first few speech recognition systems were being created, IBM Shoebox was the first to get decent success with understanding and responding to a select few English words. Today, we have a number of successful examples which understand myriad languages and respond in the correct dialect and language as the human interacting with it.
You refactor your code by moving the function calls from the name-main idiom into a dedicated function, clean_corpus(), that you define toward the top of the file. In line 6, you replace “chat.txt” with the parameter chat_export_file to make it more general. The clean_corpus() function returns the cleaned corpus, which you can use to train your chatbot. For example, you may notice that the first line of the provided chat export isn’t part of the conversation. Also, each actual message starts with metadata that includes a date, a time, and the username of the message sender. To avoid this problem, you’ll clean the chat export data before using it to train your chatbot.
It continues
generating words until it outputs an EOS_token, representing the end
of the sentence. A common problem with a vanilla seq2seq decoder is that
if we rely solely on the context vector to encode the entire input
sequence’s meaning, it is likely that we will have information loss. This is especially the case when dealing with long input sequences,
greatly limiting the capability of our decoder. In this tutorial, we explore a fun and interesting use-case of recurrent
sequence-to-sequence models. We will train a simple chatbot using movie
scripts from the Cornell Movie-Dialogs
Corpus. This article will demonstrate how to use Python, OpenAI[ChatGPT], and Gradio to build a chatbot that can respond to user input.
This gives us the methods to create and manipulate JSON data in Redis, which are not available with aioredis. The Redis command for adding data to a stream channel is xadd and it has both high-level and low-level functions in aioredis. Next, we test the Redis connection in main.py by running the code below. This will create a new Redis connection pool, set a simple key “key”, and assign a string “value” to it. Also, create a folder named redis and add a new file named config.py. We will use the aioredis client to connect with the Redis database.
Conversational models are a hot topic in artificial intelligence
research. Chatbots can be found in a variety of settings, including
customer service applications and online helpdesks. These bots are often
powered by retrieval-based models, which output predefined responses to
questions of certain forms.
Now that we’re armed with some background knowledge, it’s time to build our own chatbot. We’ll be using the ChatterBot library to create our Python chatbot, so ensure you have access to a version of Python that works with your chosen version of ChatterBot. However, there is still more to making a chatbot fully functional and feel natural. This mostly lies in how you map the current dialogue state to what actions the chatbot is supposed to take — or in short, dialogue management. You can continue conversing with the chatbot and quit the conversation once you are done, as shown in the image below. I am a final year undergraduate who loves to learn and write about technology.
Each time a user enters a statement, the library saves the text that they entered and the text
that the statement was in response to. As ChatterBot receives more input the number of responses
that it can reply and the accuracy of each response in relation to the input statement increase. Recall that if an error is returned by the OpenWeather API, you print the error code to the terminal, and the get_weather() function returns None. In this code, you first check whether the get_weather() function returns None. If it doesn’t, then you return the weather of the city, but if it does, then you return a string saying something went wrong.
A Form named ‘Form’ is then created, incorporating a text field to receive user questions and a submit field. The Flask web application is initiated, and a secret key is set for CSRF protection, enhancing security. Then we create a instance of Class ‘Form’, So that we can utilize the text field and submit field values.
- For this tutorial, you’ll use ChatterBot 1.0.4, which also works with newer Python versions on macOS and Linux.
- Ultimately the message received from the clients will be sent to the AI Model, and the response sent back to the client will be the response from the AI Model.
- No, that’s not a typo—you’ll actually build a chatty flowerpot chatbot in this tutorial!
- NLP technologies are constantly evolving to create the best tech to help machines understand these differences and nuances better.
- Moving forward, you’ll work through the steps of converting chat data from a WhatsApp conversation into a format that you can use to train your chatbot.
Before I dive into the technicalities of building your very own Python AI chatbot, it’s essential to understand the different types of chatbots that exist. A successful chatbot can resolve simple questions and direct users to the right self-service tools, like knowledge base articles and video tutorials. If you scroll further down the conversation file, you’ll find lines that aren’t real messages.
This method ensures that the chatbot will be activated by speaking its name. To a human brain, all of this seems really simple as we have grown and developed in the presence of all of these speech modulations and rules. However, the process of training an AI chatbot is similar to a human trying to learn an entirely new language from scratch. The different meanings tagged with intonation, context, voice modulation, etc are difficult for a machine or algorithm to process and then respond to.
Batch2TrainData simply takes a bunch of pairs and returns the input
and target tensors using the aforementioned functions. However, if you’re interested in speeding up training and/or would like
to leverage GPU parallelization capabilities, you will need to train
with mini-batches. First, we must convert the Unicode strings to ASCII using
unicodeToAscii.
The future of chatbot development with Python holds great promise for creating intelligent and intuitive conversational experiences. Finally, in line 13, you call .get_response() on the ChatBot instance that you created earlier and pass it the user input that you collected in line 9 and assigned to query. Running these commands in your terminal application installs ChatterBot and its dependencies into a new Python virtual environment. If you’re comfortable with these concepts, then you’ll probably be comfortable writing the code for this tutorial. If you don’t have all of the prerequisite knowledge before starting this tutorial, that’s okay!
The code runs perfectly with the installation of the pyaudio package but it doesn’t recognize my voice, it stays stuck in listening… You will get a whole conversation as the pipeline output and hence you need to extract only the response of the chatbot here. In the current world, computers are not just machines celebrated for their calculation powers.
I’ve carefully divided the project into sections to ensure that you can easily select the phase that is important to you in case you do not wish to code the full application. Remember, overcoming these challenges is part of the journey of developing a successful chatbot. I know from experience that there can be numerous challenges along the way. Python, with its extensive array of libraries like Natural Language Toolkit (NLTK), SpaCy, and TextBlob, makes NLP tasks much more manageable. These libraries contain packages to perform tasks from basic text processing to more complex language understanding tasks.
In the next section, we will build our chat web server using FastAPI and Python. In addition to all this, you’ll also need to think about the user interface, design and usability of your application, and much more. I also received a popup notification that the clang command would require developer tools I didn’t have on my computer. You can foun additiona information about ai customer service and artificial intelligence and NLP. This took a few minutes and required that I plug into a power source for my computer. After creating your cleaning module, you can now head back over to bot.py and integrate the code into your pipeline.
The final else block is to handle the case where the user’s statement’s similarity value does not reach the threshold value. SpaCy’s language models are pre-trained NLP models that you can use to process statements to extract meaning. You’ll be working with the English language model, so you’ll download that.
Finally, we need to update the main function to send the message data to the GPT model, and update the input with the last 4 messages sent between the client and the model. We are sending a hard-coded message to the cache, and getting the chat history from the cache. When you run python main.py in the terminal within the worker directory, you should get something like this printed in the terminal, with the message added to the message array. In this section, we will build the chat server using FastAPI to communicate with the user. We will use WebSockets to ensure bi-directional communication between the client and server so that we can send responses to the user in real-time.
This process will show you some tools you can use for data cleaning, which may help you prepare other input data to feed to your chatbot. Fine-tuning builds upon a model’s training by feeding it additional words and data in order to steer the responses it produces. Chat LMSys is known for its chatbot arena leaderboard, but it can also be used as a chatbot and AI playground. The ChatterBot library combines language corpora, text processing, machine learning algorithms, and data storage and retrieval to allow you to build flexible chatbots. Also, consider the state of your business and the use cases through which you’d deploy a chatbot, whether it’d be a lead generation, e-commerce or customer or employee support chatbot. Operating on basic keyword detection, these kinds of chatbots are relatively easy to train and work well when asked pre-defined questions.
You can apply a similar process to train your bot from different conversational data in any domain-specific topic. In human speech, there are various errors, differences, and unique intonations. NLP technology, including AI chatbots, empowers machines to rapidly understand, process, and respond to large volumes of text in real-time. You’ve likely encountered NLP in voice-guided GPS apps, virtual assistants, speech-to-text note creation apps, and other chatbots that offer app support in your everyday life. NLP, or Natural Language Processing, stands for teaching machines to understand human speech and spoken words.
By using chatbots to collect vital information, you can quickly qualify your leads to identify ideal prospects who have a higher chance of converting into customers. Depending on how you’re set-up, you can also use your chatbot to nurture your audience through your sales funnel from when they first interact with your business till after they make a purchase. Chatbots can pick up the slack when your human customer reps are flooded with customer queries. These bots can handle multiple queries simultaneously and work around the clock. Your human service representatives can then focus on more complex tasks. Depending on your input data, this may or may not be exactly what you want.
Overall, the Global attention mechanism can be summarized by the
following figure. Note that we will implement the “Attention Layer” as a
separate nn.Module called Attn. The output of this module is a
softmax normalized weights tensor of shape (batch_size, 1,
max_length). The following functions facilitate the parsing of the raw
utterances.jsonl data file. The next step is to reformat our data file and load the data into
structures that we can work with. ChatterBot is a Python library designed to make it easy to create software that can engage in conversation.
NLTK will automatically create the directory during the first run of your chatbot. For this tutorial, you’ll use ChatterBot 1.0.4, which also works with newer Python versions on macOS and Linux. ChatterBot 1.0.4 comes with a couple of dependencies that you won’t need for this project. However, you’ll quickly run into more problems if you try to use a newer version of ChatterBot or remove some of the dependencies. Once Conda is installed, create a yml file (hf-env.yml) using the below configuration. Finally, if a sentence is entered that contains a word that is not in
the vocabulary, we handle this gracefully by printing an error message
and prompting the user to enter another sentence.
One thing to note is that when we save our model, we save a tarball
containing the encoder and decoder state_dicts (parameters), the
optimizers’ state_dicts, the loss, the iteration, etc. Saving the model
in this way will give us the ultimate flexibility with the checkpoint. After loading a checkpoint, we will be able to use the model parameters
to run inference, or we can continue training right where we left off. Note that an embedding layer is used to encode our word indices in
an arbitrarily sized feature space.

In this file, we will define the class that controls the connections to our WebSockets, and all the helper methods to connect and disconnect. When we send prompts to GPT, we need a way to store the prompts and easily retrieve the response. Now that we have a solid understanding of NLP and the different types of chatbots, it‘s time to get our hands dirty.
On the right side of the screen, you’ll watch an instructor walk you through the project, step-by-step. Training the chatbot will help to improve its performance, giving it the ability to respond with a wider ai chatbot python range of more relevant phrases. Over 30% of people primarily view chatbots as a way to have a question answered, with other popular uses including paying a bill, resolving a complaint, or purchasing an item.
WebSockets are a very broad topic and we only scraped the surface here. This should however be sufficient to create multiple connections and handle messages to those connections Chat GPT asynchronously. GPT-J-6B is a generative language model which was trained with 6 Billion parameters and performs closely with OpenAI’s GPT-3 on some tasks.
Next you’ll be introducing the spaCy similarity() method to your chatbot() function. The similarity() method computes the semantic similarity of two statements as a value between 0 and 1, where a higher number means a greater similarity. In addition, you should consider utilizing conversations and feedback from users to further improve your bot’s responses over time.
NLP technologies are constantly evolving to create the best tech to help machines understand these differences and nuances better. The best part is you don’t need coding experience to get started — we’ll teach you to code with Python from scratch. It is fast and simple and provides access to open-source AI models.
We’ve all seen the classic chatbots that respond based on predefined responses tied to specific keywords in our questions. To find out, I dove right in, starting by understanding the basics and building something tangible — a chatbot! And not just any chatbot, but one powered by Hugging Face’s Transformers. Congratulations, you now know the
fundamentals to building a generative chatbot model!
The main route (‘/’) is established, allowing the application to handle both GET and POST requests. Within the ‘home’ function, the form is instantiated, and a connection to the Cohere API is established using the provided API key. Upon form submission, the user’s input is captured, and the Cohere API is utilized to generate a response. The model parameters are configured to fine-tune the generation process. The resulting response is rendered onto the ‘home.html’ template along with the form, allowing users to see the generated output.
First, we’ll explain NLP, which helps computers understand human language. Then, we’ll show you how to use AI to make a chatbot to have real conversations with people. Finally, we’ll talk about the tools you need to create a chatbot like ALEXA or Siri. Also, We Will tell in this article how to create ai chatbot projects with that we give highlights for how to craft Python ai Chatbot. Therefore, you can be confident that you will receive the best AI experience for code debugging, generating content, learning new concepts, and solving problems. ChatterBot-powered chatbot Chat GPT retains use input and the response for future use.
You can use your desired OS to build this app – I am currently using MacOS, and Visual Studio Code. Redis is an in-memory key-value store that enables super-fast fetching and storing of JSON-like data. For this tutorial, we will use a managed free Redis storage provided by Redis Enterprise for testing purposes. Sketching out a solution architecture gives you a high-level overview of your application, the tools you intend to use, and how the components will communicate with each other.
It’ll readily share them with you if you ask about it—or really, when you ask about anything. In lines 9 to 12, you set up the first training round, where you pass a list of two strings to trainer.train(). Using .train() injects entries into your database to build upon the graph structure that ChatterBot uses to choose possible replies. The call to .get_response() in the final line of the short script is the only interaction with your chatbot.
