What is Chatgpt? How to Use? Everything you Need to Know

What Is ChatGPT?

ChatGPT is an advanced language model developed by OpenAI. It is based on the GPT (Generative Pre-trained Transformer) architecture. This model is designed to generate human-like responses to text-based prompts, making it suitable for conversational interactions.

ChatGPT has been trained on a vast amount of textual data from the internet, allowing it to identify and learn patterns, grammar, and context. It can understand and generate coherent responses, making it useful for various applications, such as answering questions, engaging in discussions, providing explanations, and assisting with creative writing.

Who Created ChatGPT?

OpenAI, an artificial intelligence research laboratory and company, created ChatGPT. OpenAI has been at the forefront of developing advanced language models, and ChatGPT is one of their most notable creations.

OpenAI has released several versions of its language models, including GPT-3, GPT-3.5, and the latest version, ChatGPT 4. It continues to conduct research and develop innovative AI technologies.

How Big a Deal is ChatGPT?

Microsoft commented that ChatGPT is an invention as important as the PC and the internet. It is, in fact, a significant development in the field of natural language processing (NLP) and artificial intelligence (AI). Its predecessor, GPT-3, garnered widespread attention and demonstrated the potential of large-scale language models. ChatGPT, built upon the GPT-3 architecture, has further refined and enhanced the model’s capabilities, making it even more competent in generating human-like text responses.

The release of ChatGPT has generated excitement and interest due to its ability to engage in more interactive and conversational exchanges. It has shown promise in various applications, such as customer support, content generation, language translation, and educational assistance. Its versatility and adaptability make it valuable in diverse domains.

With what has been observed so far, ChatGPT has the potential to greatly impact various industries and applications that rely on human-computer interactions.

How Does It Work?

In simple words, ChatGPT predicts which word comes after another from what has happened in the large chunks of textual data that it has been previously trained on. Let’s delve a little deeper into its functioning to give you a better understanding.

When a user chats with ChatGPT, it breaks down your messages into small parts called “tokens” that it can understand. It tries to determine the meaning and context of the user’s written words.

Based on its training, ChatGPT generates a response by assembling the tokens it understands. It tries to develop a relevant and sensible answer based on what it has learned from the text it was trained on.

The training process helps ChatGPT understand grammar, facts, and how words fit together. However, it is worth mentioning here that ChatGPT can only generate responses based on what it learned before September 2021, and it may not be aware of recent events or changes. Hence, it is not infallible and has been known to respond with inaccurate information.

How Can You Access ChatGPT?

To access ChatGPT, follow the below-mentioned steps:

  • OpenAI website: Go to the OpenAI website.
  • Signing up: Sign up for an OpenAI account.
  • Verification: Verify your login method (mobile number/ email id)
  • Terms and conditions: Accept the terms and conditions for using ChatGPT.
  • Start using ChatGPT: You’re all done and can start using ChatGPT.

ChatGPT: How to Use

There are several use cases of ChatGPT. Some of the most used applications of ChatGPT are as follows:


ChatGPT can be used for research purposes. You can ask ChatGPT questions, which will retrieve information for you, much more streamlined than search engine responses. ChatGPT provides answers, explanations, definitions, or facts based on its training data.

Creative writing assistance

ChatGPT can generate ideas, prompts, plots, or even storylines. For example, if you ask it to write a plotline for a thriller with two well-known actors, ChatGPT can generate it for you. It also helps with creative blocks by giving you ideas and just the nudge you need to let open your creativity.

Language translation

You can use ChatGPT to help with language translation tasks. You can input text in one language and ask it to translate it into another language. It currently supports over 95 languages.

Content generation 

ChatGPT can help generate articles, blog posts, or social media content. You can provide a topic or a brief description, and ChatGPT can provide paragraphs or sections of text related to the topic.

Conversational chatbot

ChatGPT can be used as a chatbot to engage in conversations. You can chat with it on various topics, discuss interests, or seek advice.

What is the Difference Between ChatGPT and a Search Engine?

ChatGPT is not a search engine; it is an AI-powered chatbot. While search engines retrieve information from the internet, ChatGPT provides information from its vast training set data. The information cut-off point for this data is September 2021, as mentioned before. Therefore, it cannot provide information regarding the latest developments or news. 

For example, it can answer questions like ‘What are the seven wonders of the world?’ but it won’t help you if you ask, ‘What is the latest news of the ongoing match today?’

Limitations of ChatGPT

As mentioned in the blog earlier, ChatGPT has quite a few limitations as an AI Chatbot. From its lack of current-day information to biases in training information, here are some of the limitations of ChatGPT that every user needs to be aware of:

Lack of real-time information 

ChatGPT’s training only includes data up until September 2021. It does not have access to current or real-time information, so it may not be aware of recent events, news, or developments after its training data cutoff.

Inaccuracy and incorrect responses

ChatGPT can sometimes provide inaccurate information. The model’s responses are based on patterns and information learned from the training data, which may contain errors, biases, or outdated information.

Bias in training data

Continuing with the previous point, the training data for ChatGPT is collected from the internet, which can introduce biases present in the data. As a result, ChatGPT may exhibit biases in its responses or amplify existing societal biases that can hurt particular communities or individuals.

Can You Integrate ChatGPT with Other Platforms?

ChatGPT can be integrated with other platforms and applications like virtual assistants, chatbots, etc. OpenAI provides an API (Application Programming Interface) that allows developers to integrate ChatGPT into their own software or services. This integration enables the use of ChatGPT’s conversational capabilities within existing platforms.

Integrating ChatGPT through the OpenAI API requires signing up for a unique API key and following the documentation and guidelines provided by OpenAI. This allows developers to leverage ChatGPT’s capabilities and provide conversational experiences to users within their own platforms or services.

Does ChatGPT Have a Paid Service?

OpenAI launched a pilot subscription plan called ChatGPT Plus service, which is available for $20/month. It allows developers to access and use ChatGPT and other OpenAI models. The API provides a scalable and programmatic way to integrate ChatGPT into applications, products, or services.

The distinction between paid and unpaid versions of ChatGPT lies in the level of access and usage privileges. In general, unpaid ChatGPT provides free access to a broader user base, making it more accessible to anyone.

However, unpaid versions often come with limited functionality and features compared to their paid counterparts. These limitations can include restricted usage, such as limitations on the number of queries or time duration per session.

Paid versions offer enhanced features, advanced customisation options, and better performance due to higher priority access to server resources. 


ChatGPT has been all over the talk of industries, and many leaders and layperson alike have voiced their praise and concern regarding this revolutionary AI tool. It can be used in human collaboration to make human work easier, but all its limitations must be noted and acknowledged before using it.
