What is ChatGPT and how it works

ChatGPT is a web-based AI text generator that helps to write your questions and get prompt answers immediately. The full name of ChatGPT is Chat Generative Pre-trend Transformer. This is simple and free to everyone. ChatGPT’s website is chat.openai.com. ChatGPT is the newest way to seek information in contrast to established search engines, where one spends hours browsing through with plenty of website’s link ranked by the search engines. In this way you save your time by not browsing numerous search results produced by search engines. But ChatGPT is no exaggeration. Because ChatGPT has only been around for a short time. ChatGPT was developed by OpenAI, an American artificial intelligence (AI) research company. It was launched on 30 November 2022. Chat GPT was started by Sam Altman in 2015 in association with Elon Musk. But Elon Musk abandoned the project after 1 to 2 years. Afterwards, Microsoft invested a lot in it. According to Google’s search results, by January 2023, its users has increased to 100 million. ChatGPT is only available in English now. But it will be available in many languages in the future, according to OpenAI. I have watched many YouTube videos and read many website articles where people have successfully tried ChatGPT to write essays, YouTube video scripts, cover letters, biographies, leave applications, emails, etc., and all of them have claimed accurate results. As if they were written by humans.

Before understanding how it works, we must first understand its underlying engine. Over 500 billion data tokens were used to train ChatGPT, which uses the algorithms GPT-3 or Generative Pre-trained Transformer 3. But OpenAI has recently announced the latest GPT-4 version. Both GPT-3 and GPT-4 are based on Large Language Models (LLMs). GPT-4 is more powerful than GPT-3, but only available to ChatGPT Plus subscribers. While GPT-3 is still free for everyone. The Wikipedia definition of a large language model (LLM) says that it consists of a neural network with many parameters (typically billions of weights), trained on large amounts of unlabelled text. Language models are probability distributions over word sequences.

The main feature of ChatGPT is that it remembers your conversations. Whatever questions you ask, ChatGPT uses this as a reference for conversation. You can also ask ChatGPT to make any corrections or revisions. It will do it for you. As a result, you feel as though you are conversing with another human being.

How does it work?

When you ask a question by typing text into ChatGPT, GPT-3 processes the text using tokens. Tokens are common sequences of characters found in text as you can see in the following picture. By understanding the statistical relationships between these tokens, GPT-3 produces the next token. Taking the last paragraph of the previous section and feeding it into GPT-3 model will help us better understand how tokens are generated. You can also learn about tokenizers by following this weblink: https://platform.openai.com/tokenizer

GPT-3 has been trained with 500 billion tokens, so the neural network behind its backbone has already established meaningful relationships and weights. To establish meaning relations based on statistical analysis, these massive tokens or data sets are taken from various sources, such as books, articles, public databases from the internet. After you insert text, ChatGPT creates a prompt answer based on these established facts.

Advantages of ChatGPT

Its biggest advantage is that when you search for anything on chatgpt, you get a direct answer to your question in detail.

Searching on search engines brings up different websites after the search result, but not on Chat GPT. Here you are taken directly to the results.

Another wonderful facility has been launched in this area as well. If you are not satisfied with the result you see when you search something, you can provide its information to Chat GPT, which in turn will update the result continuously.

Users of this service are not charged a penny, that is, it is free of charge.

Disadvantages of ChatGPT

There is a limited amount of data available to them. Its training ended at the beginning of 2022. After March 2022, you will hardly hear about the events in such a situation.

ChatGPT currently supports only English language. Thus, it will be useful for those who understand English. In the future, other languages will also be supported.

You can use it for free as long as it is in the research period. After the research period, the user will have to pay to use it. However, no information has been provided about how much this money will be.

Applications of ChatGPT

The ChatGPT software can be used in a variety of applications, particularly in text-based communication. For instance, it can be used to power customer service chatbots, which can expedite customer service inquiries. When there are many customers, it can enable the businesses to answer to their customers quickly. Furthermore, it can be utilized as a language translation tool, facilitating communication between people who speak different languages. ChatGPT can help people improve their writing skills and give them ideas for writing. Even teachers can use it to help students learn better. Overall, ChatGPT is a useful tool that can make it easier to communicate and be more productive. The ChatGPT can also provide feedback on written work and content creation suggestions. Personalized learning experiences can even be provided in educational settings, helping students improve their writing skills. In general, ChatGPT is a versatile tool that can enhance communication, productivity, and creativity in numerous ways.


OpenAI has developed ChatGPT, a powerful language model that combines deep learning algorithms with text-based prompts to generate human-like responses. As a result of extensive training on text data, it has the capability of producing highly coherent and contextually relevant responses. Several applications are possible with ChatGPT, such as customer service chatbots and language translation tools. As a result of its ability to learn and adapt based on user interactions, it is an extremely versatile and powerful tool for both businesses and individuals. The ChatGPT platform continues to revolutionize natural language processing through its impressive performance and potential for innovation.
