Artificial intelligence or AI has been one of the most fascinating aspects of technology in the 21st century. AI began in myths and science fiction novels and today, it is used everywhere from a smartphone to advanced robotics. Put in simple terms, AI is a simulation of human intelligence in a mechanized form. So any machine or software that is capable of simulating “thought” can be considered an AI. Some common examples include maps and navigation systems and voice assistants in smartphones as well as self-driving cars. But the application of AI is constantly increasing in today's world. AI is now fully capable of generating sensible content without any manual input. Yes, we are talking about Generative Pre-trained Transformer (GPT). As rumors around the development of GPT-4, the fourth iteration of the software, rises to fever pitch, we take a look at what this intriguing piece of technology is all about. 

Language processing and conversations have always been considered a big leap for AI. An AI which can, not only understand when you say something to them, but also reply in a meaningful way has been a challenge that data scientists have been trying to solve for decades. Natural Language Processing (NLP) models used to be the standard even a few years ago, which were capable of performing a specific task given to them.

However, OpenAI, a San Francisco-based company made a breakthrough with its GPT model. GPT is a deep learning model trained on the data available on the internet. It can answer a question, have conversations, write codes as well as generate and summarize content.

GPT-1 paper was published in 2018 which focused on sentiment analysis, classification and learning from unlabeled data. It had 117 million
