An overview of OpenAI GPT-3 algorithm

OpenAI GPT-3 algorithm

GPT-3 employs and augments the GPT-2 model architecture such as pre-normalization, modified initialization, and reversible tokenization. It gives better performance on several Natural Language Processing (NLP) tasks and benchmarks in zero, one, and very few-shot settings.

Generative Pre-trained Transformer 3 (GPT-3) is an auto-regressive AI language model, which was created by OpenAI, which is an artificial intelligence research laboratory, which is situated in San Francisco, California, USA.

OpenAI GPT-3 is a huge artificial neural network that uses deep learning to produce human-like text and was trained on large text datasets with thousands of billions of words. It is the third-generation AI language prediction model in the GPT-n series and the successor to GPT-2.

In simple words, GPT-3 was shown how millions of people write, and was taught how to pick up on writing patterns based on user entry. Once a few inputs are given the model gets generated intelligent text following the submitted pattern and structure. It is also the largest AI language model studying on 175 billion parameters and working on a massive corpus of text.

The OpenAI GPT-3 is based on 175 billion parameters and is by far has highest accuracy than its predecessors. For instance, GPT-2 had only 1.5 billion of parameters, and Microsoft Turing NLG – 17 billion of them. Thus, the power of GPT-3 is significantly surpassing the alternatives.

The power of GPT-3

GPT-3 has the potentiality to do many numbers of natural language tasks and produces human-like text. It is trained by using a mixture of the following large text datasets:

  • Common Crawl
  • WebText2
  • Books1
  • Books2
  • Wikipedia Corpus

The final dataset has a massive amount of web pages from the internet, a large collection of books, and all of Wikipedia. Researchers took help of this dataset with thousands of billions of words to train GPT-3 for the generation of text in English and also in several other languages.

The several tasks that GPT-3 can do to make it more useful are by performing the following tasks:

  • Question answering
  • Text classification
  • Text generation
  • Text summarization
  • Reading comprehension
  • Writing tasks
  • Named-entity recognition
  • Language translation

How GPT-3 works

A language model in GPT-3 is a program that calculates the word or even the character which must present in a text given in relation to the words around it. This is known as the conditional probability of words.

It is a generative neural network that offers out a numeric score or a yes or no answer. It also generates long sequences of the original text as its output.


  • noun + verb = subject + verb
  • noun + verb + adjective = subject + verb + adjective
  • verb + noun = subject + verb
  • noun + verb + noun = subject + verb + noun
  • noun + noun = subject + noun
  • noun + verb + noun + noun = subject + verb + noun + noun

The specialty of GPT-3

The main specialty of GPT-3 is the ability to respond intelligently to minimal input. It is extensively trained on billions of parameters and can generate texts of up to 50,000 characters without any supervision. This one-of-a-type AIneural network that can generate texts at an amazing quality that makes it very difficult for a typical person to understand whether the output was written by GPT-3 or a human. It also writes blog posts, stories, essays, poems, tweets, press releases, technical manuals, and, business memos with better grammar.

End notes

There’s a lot of hype for the OpenAI GPT-3  deep-learning language model right now. One can say that in the coming years GPT-3 will be functioning beyond the text, which includes pictures and videos. Experts predict that it can translate words to pictures and pictures to words.
