What is GPT-3 and how does it work?

GPT-3 is an advanced language prediction model that uses deep learning algorithms to generate text based on user input. It has been pre-trained on a massive corpus of text, allowing it to comprehend language structure and function.

With GPT-3, users can input a string of text, and the model will generate the most appropriate and helpful text response based on its training. It can perform a variety of language tasks, like translating a language, summarizing a text, or writing a creative article.

GPT-3 is able to accomplish these feats by using a technique called unsupervised learning. It disassembles text, examines how words and sentences are constructed, and reconstructs them to create a new text. It does all this by searching through the enormous amount of data it has been trained on and selecting the most likely response.

As it makes these selections, the model’s “weighting” mechanism assigns a value to the approach that produced the correct response. Over time, the algorithm “learns” which approaches are most likely to produce accurate results and improves its performance accordingly.

GPT-3 is the largest neural network ever built, with 175 billion weights or parameters, allowing it to analyze queries and store them in its memory. Its massive computational resources enable it to generate responses that are often indistinguishable from human-generated text.

Let’s take a detailed look at what a parameter is and how it powers the performance of GPT-3.

The Power of GPT-3’s 175 Billion Parameters

GPT-3 is remarkable for its sheer size, boasting 175 billion parameters, making it one of the most extensive and complex language models to date.

The number of parameters within a machine learning model determines its complexity and overall power. A parameter is a variable within a model that determines how it processes data. It helps the model evaluate the relationships between words and phrases so it can understand natural language more accurately. Essentially, parameters are the knobs and dials that data scientists adjust to make their models work better.

With 175 billion parameters, GPT-3 has an unparalleled wealth of knowledge, which allows it to analyze and generate complex language data with ease. Here is an image showing the growth of the GPT model over the years in terms of the number of trainable parameters.

To make a machine learning model work well, you also need to train it using a lot of data. The GPT-3 model created by OpenAI was trained on a huge amount of text data – about 45 terabytes! That’s like having 9,000 DVDs filled with information.

Of course, OpenAI used many different sources to extract this data. They gathered text from sources like books, articles, and websites. Each source of data was important and helped the model learn different things.

In total, the GPT-3 model was trained for a long time – about 300 billion times! And during this training process, the model read all of the text data and learned how to generate new text on its own.

12 billion




(datasets that contain the text of various books)

55 billion




(dataset that contains articles from the online encyclopedia of the same name)

3 billion



As you can see in the above table, to teach GPT-3 how to understand language, OpenAI trained it on huge data sets from different sources like books, websites, and Wikipedia. The dataset that had the most influence on GPT-3’s training was Common Crawl, which provided 60% of the data. WebText2 was the next most influential, and the two book datasets, Books1 and Books2, each had 8% influence. Finally, Wikipedia had the smallest influence, with just 3% weightage in the training mix.

The training process involved going through each dataset multiple times until GPT-3 had processed 300 billion pieces of language data, which is a lot! Each time GPT-3 went through a dataset, it was called an “epoch.” So, for example, imagine that you’re trying to learn a new language. To become fluent, you need to practice reading and speaking a lot, right? GPT-3 is like a language learner, but instead of books and flashcards, it learns from huge amounts of written text.
