ChatGPT vs GPT3 vs OpenAI: What Are The Key Differences?

Over the past couple of months, you’ve probably heard a lot about ChatGPT, GPT-3 and OpenAI.

There has been a huge increase in search volume and demand for ChatGPT, but some of the jargon can be a little bit confusing. That’s what we’re here for.

We’ve broken down the differences between ChatGPT, GPT-3 and OpenAI to make it all a little easier to understand.

What’s the Difference Between ChatGPT and OpenAI?

As AI technology becomes more popular, it’s important to understand the key differences between ChatGPT, OpenAi, and GPT-3.

They are pretty similar and all kind of work together, but actually there a few differences:

  • The main thing to understand is that ChatGPT was built by the non-profit OpenAI.
  • ChatGPT uses the technology GPT-3.5
  • OpenAI also has their service ‘OpenAI Playground‘, which you can choose which GPT to use.

That can be a little bit confusing, so we’ve broken it down further below.

In the sections below, we’ll break down all the differences between ChatGPT, OpenAi, and GPT.

What is ChatGPT?

ChatGPT is a step forward in natural language technologies from the OpenAI team.

It’s a text-generating technology that uses large neural networks to generate plausible responses to input text. It’s used to power interactive conversations, and has been tested as an application in customer support and marketing automation.

ChatGPT is trained on massive datasets of conversations and can understand context to generate more natural-sounding responses than existing systems.

Ask ChatGPT anything.

The technology is based on the OpenAI GPT-3.5 model, which is an advanced version of the language models used in Google Translate and other AI applications.

ChatGPT is designed with a two track approach: one track to output natural-sounding responses, and another track focused on generating appropriate content for the conversation at hand.

As such, it can be trained with both conversational data (e.g., man-to-machine) as well as factual information (e.g., machine-to machine).

This makes it particularly powerful for answering questions about topics like products or services – when paired with existing datasets related to those topics ChatGPT can output highly relevant information quickly and accurately without needing manual tuning.

The Key Difference

The key difference between GPT-3 and ChatGPT is that with ChatGPT you add a conversational AI layer which serves as more than just a text generator.

This creates “real” conversations with your users through intelligent responses, that mimic true human conversation – something that was not possible with GPT-2 which was focused purely on text generation alone.

What is OpenAI?

OpenAI is a research laboratory that focuses on artificial intelligence (AI).

OpenAI’s mission is to ensure that AI gives everyone a fair chance so that humanity can achieve its maximum potential.

OpenAI was founded in December 2015 with Sam Altman, Greg Brockman, Ilya Sutskever, Wojciech Zaremba and many other prominent researchers in the field of AI as founders.

OpenAI initially created an unrestricted research laboratory to develop unsupervised machine learning through deep learning techniques such as reinforcement learning and generative models. They produced a number of algorithms over the years and developed several projects such as GPT-3 (Generative Pre-trained Transformer 3), OpenAI Playground and ChatGPT.

OpenAI has also made significant improvements to its GPT-3 language model, which uses natural language processing to create human-like text from limited user inputs.

GPT-3 is based on a large dataset of real text written by people around the world for various applications such as fiction writing or presenting news articles.

It has been featured in many publications across different industries as it has become a powerful semantic and syntactic tool for generating accurate texts with just a few words as input.


GPT-4 is also planned to be deployed in late 2023 and is expected to be 100 times more powerful that GPT-3.

So, to sum it up – OpenAI is an AI research lab that creates powerful algorithms like GTP-2, GPT-3 and soon GPT-4, using natural language processing techniques and focuses primarily on unsupervised machine learning through deep learning approaches like reinforcement learning and generative models.

This allows computers to mimic human language more accurately than ever before.

What is GPT-3?

Ah, GPT-3. Where do we begin?

GPT-3 stands for General Pre-trained Transformer 3. It’s a massive artificial intelligence (AI) language model developed by OpenAI and released in June 2020.

It’s based on their previous generative models, GPT and GPT-2, but it is much larger and more powerful – so much so that many experts consider it to be the cornerstone of the next generation of AI technology.

GPT-3 contains 175 billion parameters – far more than all other AI language models combined – and as such, offers unparalleled capabilities in natural language processing, text analysis, and natural language understanding (NLU).

How Many Parameters Will GPT-4 Have?

Just like ChatGPT 3, ChatGPT 4 will have the capability to do a variety of tasks – from text generation and language translation to text summarization, question answering, chatbot, and automated content generation.

There’s been a lot of speculation about how many parameters GPT-4 will have – some say it could have as many as 100 trillion. But the truth is, we just don’t know yet.

We can be sure it will be somewhere between 10 and 100 trillion, but until we have the official word, we won’t know for sure!

ChatGPT and the Development of GPT

ChatGPT is based on the GPT-2 language model developed by OpenAI.

It uses a bidirectional encoder-decoder architecture to generate natural language responses to questions. In other words, when you input data into ChatGPT, it generates conversational output based on what it learned from the data it was given.

The biggest advantage of ChatGPT is its speed – it can generate natural interactive dialogue in real-time. It’s also highly customizable and can be used for a range of tasks such as chatbot development, natural language processing (NLP), voice recognition, and more.

GPT-2 to GPT-3

OpenAI’s GPT-2 was the world’s first widely successful language model, introduced in 2018. It uses a method called “transformers” to convert input text into context-aware word embeddings that capture relationships among words in the sentence, rather than each word being treated independently.

The model is trained on vast amounts of data and can produce accurate results when given an incomplete sentence or text prompt.

OpenAI’s latest version, GPT-3 (Generative Pre-trained Transformer 3), improves on GPT-2 with more powerful language modeling capabilities than ever before. It features 175 billion parameters compared to GPT-2’s 1.5 billion – an increase of over 11000%.

GPT-3’s larger size makes it more capable at understanding nuance when generating natural language responses which more closely mimic human speech.

Additionally, retraining times are faster and much smaller training datasets can be used, since some information is already pre-trained from previous models such as GPT and BERT (Bidirectional Encoder Representations).

As a result of this pre-training phase and larger dataset training process, GPT‑3 can process higher complexity tasks like:

  • Sentiment analysis and
  • Dialogue control better than OpenAI’s previous models by using generalizable insights learned from large amounts of data instead of relying on specific task training algorithms such as reinforcement learning or supervised learning methods.

This allows it to outperform thoroughly trained algorithms such as rule based chatbots or A/B testing models where user intent is not always accurately identified.

Ultimately both GPT‑2 and GPT‑3 offer unique advantages for specific problems related to conversational artificial intelligence and natural language processing applications but choosing one over the other requires careful consideration depending on your project’s needs.
