GPT-4 vs. GPT-3: What’s the Difference?

GPT-4 vs GPT-3


GPT-3(Generative Pre-trained Transformer 3) and GPT-4(Generative Pre-trained Transformer 4) are both natural language processing (NLP) tools developed by OpenAI that uses machine learning to generate text according to the text input that is provided by the user. When comparing GPT-3 vs GPT-4, it is obvious to some extent that GPT-4 is going to be better than its predecessor. GPT-3 was released in 2020 and quickly gained popularity due to its impressive language capabilities and versatility. ChatGPT-4, the latest version of the tool, was announced in late 2021 and was released for commercial use on 14 march 2023 and has since generated significant interest in the NLP community.

Choosing the right language model is crucial for achieving optimal results in NLP tasks. In the following article, we’ll explore the architectural distinctions between GPT-3 and GPT-4 and investigate how these discrepancies influence their individual performances and if GPT-4 is better than GPT-3.


Both ChatGPT-3 and ChatGPT-4 use a transformer-based architecture, which is a type of neural network that is particularly effective in handling natural language tasks. Despite their apparent similarities, the architectures of these two systems harbor some notable differences that set them apart. Both of these systems are quite good at providing human feedback.

ChatGPT-3 Architecture

ChatGPT-3 uses a 175 billion parameter transformer-based architecture, which was the largest and most complex architecture of any NLP tool before ChatGPT-4. It consists of 96 attention layers, with each layer containing 16 heads. This architecture enables ChatGPT-3 to handle a wide range of language tasks, including language translation, question answering, and even creative writing.

ChatGPT-4 Architecture

On the other hand, OpenAI has been a little secretive about ChatGPT-4, and the details of its architecture have not yet been released. However, it is expected to have a larger parameter count than ChatGPT-3(approx. 100 trillion) and to incorporate new techniques and approaches to language processing.

The effects of architectural disparities on the efficacy of language models cannot be overstated. Take, for instance, the potential benefits of increased parameter counts, which can equip models to tackle more intricate language tasks, or the advantages of additional layers or heads, which can augment their capacity to capture the intricacies of language in all its manifold forms.

One more important note is that ChatGPT-3 is only a singular modal model which can only accept data in one format, in the shape of written text. On the other hand, ChatGPT-4 is based on a multi-modal model which can accept images and videos as well.

In the next sections, we will compare the performance, training data, language capabilities, use cases, and cost of ChatGPT-3 and ChatGPT-4 to further examine the differences between these two language models.
