Generative Pre-Trained Transformer 3 (GPT-3) and Generative Pre-Trained Transformer 4 (GPT-4) are two of the latest technologies in artificial intelligence (AI). GPT-3 was released in May 2020, and its successor, GPT-4, is expected to be launched in early 2023. With the ever-increasing popularity of ChatGPT, which was developed by the same company as GPT-3, the question now arises as to what extent OpenAI plans to release the GPT-4 language model. We’ll give you a detailed look at what GPT-4 vs. GPT-3 might look like.

What are the GPT Models?

A Generative Pre-Trained Transformer (GPT) is a sophisticated neural network used to train large language models. The network uses large amounts of publicly available Internet text to simulate human communication.

The GPT models GPT-4 and GPT-3 are both such Language Models which are used to generate text. GPT-4 is a further development of GPT-3, which contains more inputs and has a larger data set volume. Both models use machine learning to generate text in natural language.

The Evolution of GPT: A Journey from GPT-1 to GPT-3

The evolution of GPT (Generative Pre-trained Transformer) models reflects a journey of advancements in natural language understanding and generation. Developed by OpenAI, these models have progressed through multiple iterations, from GPT-1 to GPT-4. Here, we outline the main differences and improvements in each version:


  • Introduced in 2018
  • Based on the Transformer architecture from the paper “Attention is All You Need”
  • 117 million parameters
  • Unsupervised pre-training followed by supervised fine-tuning
  • Demonstrated strong results in a range of natural language processing tasks


  • Launched in 2019
  • 1.5 billion parameters
  • Improved unsupervised pre-training with a larger dataset (WebText) and longer sequences
  • Better performance on various NLP benchmarks
  • Generated more coherent and contextually relevant text
  • Controversy surrounding its release due to concerns about potential misuse (e.g., generating fake news)

Improvements from GPT-1 to GPT-2:

  • Increased number of parameters, leading to better performance
  • More advanced training methodology
  • Improved performance on NLP benchmarks and text generation

  • Released in 2020
  • 175 billion parameters
  • Trained on a much larger dataset, including books, articles, and websites
  • Demonstrated near-human performance on several NLP tasks, such as translation, summarization, and question-answering
  • Enabled zero-shot and few-shot learning
  • Introduced the OpenAI API for GPT-3, allowing developers to build applications

Improvements from GPT-2 to GPT-3:

  • Significantly increased number of parameters
  • Improved performance on a wide range of NLP tasks
  • Ability to learn with minimal training data (zero-shot and few-shot learning)
  • API for developers to build applications

In summary, the evolution of GPT models has been marked by significant improvements in language understanding and generation capabilities. The models have grown in size (number of parameters) and have been trained on increasingly large and diverse datasets. This has led to enhanced performance on a wide array of NLP tasks, including translation, summarization, and question-answering.

GPT-4 vs. GPT-3: How is the performance measured in comparison?


To measure the performance of GPT-4 compared to GPT-3, different approaches are used. The first approach is to measure precision and accuracy. This involves comparing the results of one task with the results of other tasks to determine which are better. This approach can be used to determine how well GPT-4 vs. GPT-3 performs on a given task.

Another approach is to measure the ability to deal with new language. GPT-4 and GPT-3 are tested for their ability to understand and process new words and sentences (natural language processing). This is especially important for use cases where the goal is to identify and respond to new contexts.

The last approach concerns the speed of the model. In this case, you test GPT-4 and GPT-3 to see how quickly they can respond to requests. The faster the model responds, the more efficient it can be. This is a critical factor for many use cases in AI or other areas of computer technology.

Overall, these approaches provide a clear picture of the performance of GPT-4 vs. GPT-3. Using their different methods, researchers can identify which model is better suited for specific use cases in AI or other technologies. Thus, measuring the performance of GPT-4 compared to GPT-3 provides an essential basis for developing new technologies in the future.

As of now, GPT-4 has just been released, so it is not possible to go into a detailed technological comparison of GPT-4 vs GPT-3 yet. However, in terms of performance or capabilities advancements can already be seen. Here are the key changes that we can see in GPT-4 vs GPT-3:

GPT-4 vs. GPT-3: Which model is better now?
GPT-4 and GPT-3 are both powerful technologies that can be used to generate text using AI. Although the two are considered similar, there are some significant differences in the applications.

Both models have their advantages and disadvantages in comparison with each other. First of all, it should be noted that GTP-3 can solve basic problems faster than GTP-4 because of its smaller parameter set and smaller number of records. Therefore, it often makes more sense to use GTP-3 instead of GTP-4 for basic tasks. However, for more demanding tasks you need a higher parameter set and more data sets – this is the advantage of GTP-4: it provides greater accuracy for difficult tasks thanks to its larger parameter set and data set volume.

For this reason, there is no general consensus on which method is better: for simple tasks, it may be useful to work with GTP-3; however, for more challenging problems, it is often recommended to use GTP-4 – especially when the accuracy of the results is a priority. Both models have their place in the world of machine learning – but ultimately, the key is always your personal preference in choosing the right approach for your specific use case!

GPT-4 vs. GPT-3: Artificial intelligence applications with the two systems

Overall, both AI systems enable impressive results in various artificial intelligence application areas. While GPT-4 is more powerful than GPT-3, it does not offer the same scalability or flexibility. Depending on the specific requirements of an organization, the best AI application should be chosen to achieve the best possible performance. Possible applications may include:

  1. Content creation: From 18th century poems to modern blog articles, GPT models can be fed any type of prompt and begin producing coherent and human-like text results.
  2. Text summarization or rewriting: Being able to generate fluent, human-like text, GPT can reinterpret any type of text document and create an intuitive summary from it. This is useful for gaining insights and analyzing, or reformulating.
  3. Answering questions: One of the main competences of the GPT software is its ability to understand language, including questions. Moreover, it can provide precise answers or detailed explanations depending on the user’s needs. This means that customer service and technical support can be significantly improved through GPT-supported solutions.
  4. AI Chat: Chatbot technology developed with GPT software can become incredibly intelligent as seen with CHatGPT. This can create virtual assistants with machine learning that can help professionals complete their tasks regardless of the industry….
