Some chatbots have already garnered immense publicity and so far extended their utility that transcends service and support. This has further led industries to build an AI chatbot like ChatGPT.

On top of the famed AI chatbots with reportedly the largest market share, and now with a disruptive status, is ChatGPT. It is an AI-powered language model developed by OpenAI. It is capable of comprehending and generating relevant responses to user prompts and questions. While noting the industrial utilities and possibilities of wider applications is critical, the topmost question amongst developers and entrepreneurs is how to build an AI chatbot like ChatGPT.

Provided the understanding that AI chatbots enrich customer experience and augment engagement, enterprise owners as well are actively looking to integrate AI-powered tools into their product infrastructure. For that, a detailed step-by-step guide on how to build an AI chatbot like ChatGPT from a technical and business viewpoint is discussed below.

Defining ChatGPT & How It Works

ChatGPT, short for Chat Generative Pre-trained Transformer, is essentially a chatbot. The chatbot is laid atop an AI-powered framework trained with over 45 terabytes of text data to generate the most probable response to a set of words fed as a prompt or question. This further enabled ChatGPT to recognize patterns and combinations from the text data to render relevant responses.

On the other hand, ChatGPT defines itself as a language model developed by the Artificial Intelligence company OpenAI. It continues elaborating on its functionalities for natural language processing (NLP) tasks such as translation, question-answering, and chatbot development.

On the technical aspect, ChatGPT comes from the GPT family of language models and is an improved version of GPT-3 (termed as ‘GPT 3.5’). ChatGPT is the byproduct of fine-tuning GPT 3 with supervised learning—with the involvement of human trainers roleplaying both as the user and the AI assistant, as well as reinforcement learning, and reinforcement learning—where trainers would rank and mark the responses by the language model for dialogue. This process altogether is referred to as Reinforcement Learning from Human Feedback (RLHF).

OpenAI, moreover, is constantly fine-tuning ChatGPT from inputs collected from users. As of writing this article, ChatGPT’s data refinery is updated till September 2021. Ergo, questions on events post-2021 are likely to be furnished with incorrect responses. On a comparative note, the accuracy rate of ChatGPT alternatives like Bard AI and Bing AI is further behind.

How ChatGPT works?

ChatGPT’s core engine is powered by the machine-learning natural language processing (NLP) system GPT. So when a query input is entered, it analyses the enormous text data, identifies the most relevant pattern, and relays the response based on it.

To briefly list down this process in a step-by-step form:

1. Identification & Categorization — ChatGPT starts by identifying them as prompts, questions, or conversations.
2. Mathematical Assertion — It then encodes the query into smaller pieces and gives each word a mathematical value.
3. Prediction & Response — This expression is then determined to draw the context, and predict the best sequence of words to use as a response.

Key Components of ChatGPT

To build an AI chatbot like ChatGPT, one of the most significant aspects to take into consideration is its features. From the definition of ChatGPT, we understand that the chatbot is capable of comprehending conversations and presenting relevant responses. The key components on the tech side include continuously refined datasets, a conversational interface, ML algorithms, and an extensive feedback system.

To summarize ChatGPT features, these include:

1. Easy and efficient ChatGPT integration with diverse platforms through a private OpenAI API access key.
2. Ability to answer follow-up questions with minimum detail and facilitate seamless conversations.
3. Ability to render and iterate human tasks across multiple fields such as scripting lines of code, writing poems and essays, composing songs, etc.

Estimated Cost Of Developing A ChatGPT-like AI Chatbot

The cost of developing an AI chatbot, like any other digital product, is accounted for by factors, operational and computational. To elaborate, the computational aspect of developing an AI-powered chatbot would include datasets, app complexity, customizations for the end user, the range of features and functionalities, and so on. While the operational cost is to be determined by the rate of outsourcing, hiring freelancers, or building an in-house team of chatbot developers.

On the computational front, the process starts by collecting data, both proprietary and those available in the public domain. But data collection is a rather tedious and pricey process. Tedious in terms that, as an enterprise, you must sequence and annotate the vast availability of unstructured data to protract your line of business. And the fees for outsourcing data annotation projects can vary from tens to hundreds to thousands of dollars. Not to mention the already high cost of accessing proprietary data sources.

In addition to data gathering, data storage is another crucial computational requisite. Most chatbot development houses take the utility of cloud-based resources like AWS, Azure, or Google Cloud for storage. In ChatGPT app development, the interface is hosted through Microsoft Azure’s cloud infrastructure. The bill of availing these cloud computing solutions can rise up on a sharp scale. To develop ChatGPT in particular, the timeline can be traced back to 2018 when GPT was first introduced. So it’s fair to state that to build an AI chatbot like ChatGPT, it might take several months.

Considering the above-discussed factors, the budget range for developing an AI chatbot like ChatGPT would fall somewhere between $90,000 to $450,000. In addition, the overall AI chatbot development timeline would be prolonged and could take up to several months.

How To Reduce The Cost of Developing An App Like ChatGPT

While overwhelming, the rate of AI chatbot development is indeed exorbitant. Yet it isn’t an intractable issue. With suitable checks and balances, the gross expense of AI-based chatbot development services can be considerably reduced.
