How to Create a Chatbot like ChatGPT

9 Feb 2023 | Mobile App Development


Since its release, ChatGPT has been the talk at almost all internet tech and marketing forums. It has taken the internet by storm and still amazes many for its capabilities. Now, many developers are looking to build ChatGPT-like alternatives. If you want to create a chatbot like ChatGPT, this article is for you.

We will discuss the seven simple steps you must consider when building an AI-powered chatbot like ChatGPT. ChatGPT is built with GPT-3, with Reinforcement Learning with Human Feedback (RFHF) to improve its effectiveness. So, how can you create your own?

Here are the four essential steps you need to create a ChatGPT-like chatbot. But first, let’s dive into a brief overview of a typical chatbot to help you understand them better.

Understanding ChatGPT-like Chatbots

To create a ChatGPT-like chatbot, you have to understand the following core tasks to base on your next project:

User request analysis

The first main task of a chatbot is to receive a user request and analyse it to determine the user’s intent. Different users may ask the same request in different ways, words, and angles. So, your chatbot must find out what the users want so that it can provide appropriate responses.

Returning the appropriate answers

Once the user makes a request, it’s the chatbot’s task to retrieve and send the right answer back to the user. You can base your chatbot responses on AI mapping from pre-trained data models or train your models to allow you to provide accurate and effective chatbot services like those of ChatGPT.

How to build a ChatGPT-like Chatbot

Step #1: Identify your goals for building a chatbot

Why should you make a chatbot for your website? Chatbots are designed with specific goals in mind. Why do you want to create a conversational chatbot? While many general reasons may come to mind, some specific purposes for your chatbots can include the following:

More importantly, an AI chatbot can help you in ways we’ve not stated above. You can use a chatbot to implement advanced, custom automation based on the user’s actions on your site. You can easily integrate it with your technological stack to allow you to have more control over the flow of conversations as you provide better and more personalised customer experiences.

Once you’ve identified the scope and the main tasks you want your chatbot to perform, you’re ready to dive deeply into understanding your customer’s behaviour, expectations, and preference. That way, you can build and provide chatbot experiences that delight the users.

Step #2: Do extensive research about your chatbot users

The second step to creating a conversational chatbot like ChatGPT is running extensive customer research. It is necessary to conduct in-depth customer research to succeed, especially for an app in a highly competitive industry.

It’s easier to dive into the specifics of your app without understanding your customers’ needs. That is why many business owners often build products based on their experiences or the opinions of others, leading to apps that don’t satisfy their users’ needs.

Building a chatbot without understanding your user’s needs can lead to less effective responses to their questions. Many developers often build their chatbots based solely on their own experiences or the opinions of others, which leads to products that do not meet the needs and expectations of the users.

Therefore, to build an effective and highly accurate chatbot for your users, you must conduct in-depth market research to understand your target audience and their needs. You need to identify the main tasks or questions that each user needs to complete or have answered.

More so, determine the best ways that users can interact with your chatbot, such as through text or voice, for better user experiences and accessibility. Ensure that you leverage natural language processing (NLP) and machine learning techniques to help your chatbot understand and respond to user requests accurately and appropriately.

Step #3: Train your chatbot and build the essential features

To train a ChatGPT-like chatbot, after defining the purpose and the scope of your chatbot, you’ll need to train your chatbot and build its architecture so that it can perform the expected tasks as required.

ChatGPT uses pre-trained models that have been fined-tuned to offer accurate responses, which makes it much more powerful. Thus, consider using pre-trained or fine-tuning existing models to speed up the development process rather than building it from scratch.

However, if you do not want to use pre-trained models, follow these steps to train your chatbot:

Gather data

The first step you need to collect to train your model is to collect large amounts of data to train your model. Gather large datasets with several sample conversations you can use to build your chatbot.

Prepare the data

The next step is preparing your data. You should clean and preprocess your sample datasets to ensure they’re ideal for effectively informing your chatbot training.

Choose a model architecture

The third step to training your chatbot models is to select an appropriate model architecture. For example, you can use a rule-based system, retrieval-based system, or generative model when training your chatbot model.

Train the model

Lastly, use the prepared data to train your chatbot model. You can do this by inputting your conversation examples into the model to see if there are any errors. And if there are errors, you should adjust the model’s parameters. Next, validate the model’s results with new data to find potential shortcomings, and repeat this step if necessary.

Step #4: Collect feedback from users & monitor chatbot analytics to improve it

The key to a successful chatbot that satisfies users is to regularly monitor and update your chatbot’s performance to ensure that it remains relevant and effective for your users. And to monitor chatbot analytics, you’ll need to measure several metrics to analyse and find ways to improve them.

The first and most important metric to measure performance is user satisfaction. Are the users finding your chatbot to be effective? Do they have issues with it or some of the responses? When you can measure the user’s satisfaction through servers or other analytics, you can answer the question above and relevant others to help you know which areas need improvement.

Another crucial metric is the task completion rate. You will understand how many user interactions are successful and the percentage that your chatbot can complete the desired tasks. Also, check the response time for these tasks, the error rates, and the abandonment rate to gain deeper insights into your chatbot’s performance.

Another metric that you must consider when analysing your chatbot performance is intent recognition accuracy. How well does your chatbot correctly identify your user’s intent? Does it understand the different angles that users might use to find answers to the same queries? The more you can answer these questions, the more you will gain better insights to improve your chatbot and enhance your user’s experiences.

Wrapping up on how to build a conversational AI chatbot

In conclusion, building an AI chatbot like ChatGPT requires careful planning, data gathering, preparation, and training using appropriate machine learning techniques.

This process can be complex and time-consuming. However, it also allows you to build a highly sophisticated and engaging chatbot that can automate your routine tasks and improve the user’s experiences.

In this article, we’ve discussed the four critical steps you must follow to help you create a ChatGPT-like chatbot that meets your needs and exceeds expectations. More importantly, remember that chatbot development is an ongoing process, and you should continuously evaluate and fine-tune your chatbot to keep it up-to-date and relevant.
