What Is ChatGPT? How It Works, How to Use It, and Why Learning It Matters in 2026

The future of AI is here, and it’s starting to shape the way we work, learn, and communicate. One of the hyped developments in generative artificial intelligence (AI) is ChatGPT. Whether it’s writing emails and resumes or helping businesses automate their operations, ChatGPT is making a name for itself as a productivity booster.

As AI skills become more in-demand, professionals and students are turning to ChatGPT courses to stay ahead. In this blog, we will understand what ChatGPT is, how it works, where to get started using it in real, practical use-cases, and how SevenMentor helps you learn such technology with job-oriented learning.

What Is ChatGPT?

ChatGPT is a conversational agent designed by training with a large language model (LLM). The system is designed to analyze natural language input and generate human-like output. Whether you’re asking something simple or representing a more complicated topic, ChatGPT can respond with an answer that is pertinent and appropriate in context.

At its core, ChatGPT is a generative pre-trained transformer, meaning that it can predict and generate text built upon patterns it has learned from huge datasets. This makes it capable of tasks such as content writing or coding, customer support, ideation and more.

Traditional bot approaches, which work with pre-programmed responses, are no match for ChatGPT’s on-the-fly reaction to any type of input.

What Does GPT Stand For?

GPT is an acronym for Generative Pre-Trained Transformer. 

Generative – It is a generator of new content, not a copier of existing text

Pre-Trained – It has been trained on a massive amount of text data before it is put to use

Transformer – It is a deep learning model that is specifically designed for the comprehension of the context of language

How Does ChatGPT Work?

ChatGPT operates by examining the input given by the user (referred to as a prompt) and making predictions about the most relevant response based on patterns learned. The model does not “think” like a human but instead processes probabilities at an advanced level to provide accurate and relevant responses.

Some of the key elements that contribute to the functionality of ChatGPT include:

Deep neural networks trained on large text corporas

Retention of context in a conversation

Reinforcement learning with human feedback

Ongoing updates for accuracy and safety

This is why prompt engineering, the art of creating effective prompts, is an important aspect of obtaining high-quality output from ChatGPT.

ChatGPT-3.5 vs. ChatGPT-4: What’s the Difference?

Knowledge about model versions is essential for anyone taking a ChatGPT course or professional Artificial Intelligence (AI) training.

ChatGPT-3.5

Fast response times

Ideal for simple content generation and answering questions

Poor reasoning skills

ChatGPT-4

Improved understanding of context

More accurate and innovative responses
