Everything You Need to Know About ChatGPT


ChatGPT is an artificial-intelligence (AI) chatbot developed by OpenAI and was released in November 2022. It is built on top of OpenAI's GPT-3.5 and GPT-4 families of large language models (LLMs) and has been fine-tuned (an approach to transfer learning) using both supervised and reinforcement learning techniques.


ChatGPT launched as a prototype on November 30, 2022 and garnered attention for its detailed responses and articulate answers across many domains of knowledge. Its uneven factual accuracy, however, has been identified as a significant drawback. In 2023, following the release of ChatGPT, OpenAI's valuation was estimated at US$29 billion.

The original release of ChatGPT was based on GPT-3.5. A version based on GPT-4, the newest OpenAI model, was released on March 14, 2023, and is available for paid subscribers on a limited basis.


It’s been a mere four months since artificial intelligence company OpenAI unleashed ChatGPT and — not to overstate its importance — changed the world forever. In just 15 short weeks, it has sparked doomsday predictions in global job markets, disrupted education systems and drawn millions of users, from big banks to app developers.

But now it’s goodbye to ChatGPT and hello ChatGPT — an even more powerful tool, sure to send even bigger ripples across the world. So what is GPT-4, how powerful is it, and how can you use it? Here’s everything you need to know:


What is ChatGPT?

Let’s start with the name. The Chat section speaks for itself — a computer interface you can interact with — while GPT is short for “generative pretrained transformer 4.” That means it’s the fourth iteration of the OpenAI software that has analyzed vast quantities of information from across the internet in order to determine how to generate human-sounding text and give users detailed responses to questions.


How can I use ChatGPT?

Most people can give basic ChatGPT a whirl by signing up with OpenAI here, although restrictions apply in some countries and territories around the world. But the newest version is currently only being offered to ChatGPT Plus subscribers for $20 a month — sign up here — and as an API tool for developers to build into their applications. You can join the waitlist here.

In the future, you’ll likely find it on Microsoft’s search engine, Bing. Currently, if you go to the Bing webpage and hit the “chat” button at the top, you’ll likely be redirected to a page asking you to sign up to a waitlist, with access being rolled out to users gradually.


Premium Service

In February 2023, OpenAI began accepting registrations from United States customers for a premium service, ChatGPT Plus, to cost $20 a month.The company promised that the updated, but still "experimental" version of ChatGPT would provide access during peak periods, no downtime, priority access to new features, and faster response speeds.

GPT-4, which was released on March 14, 2023, is available via API and for premium ChatGPT users. However, premium users were limited to a cap of 100 messages every four hours, with the limit tightening to 25 messages every three hours in response to increased demand.[43] Microsoft acknowledged that the Bing chatbot was using GPT-4 before GPT-4's official release.[44]
