Have you heard a lot about the ChatGPT application, but do you understand what the GPT acronym means? What is the significance of the GPT model in machine learning and AI? In this article, we will learn more about the GPT model and what’s new in its latest version, GPT-4.
Introduction
OpenAI’s GPT model is one of the most groundbreaking advancements in artificial intelligence for natural language processing. With its ability to automatically generate new text, answer questions, and complete sentences with a simple input from the user, GPT has changed the way we interact with computers and brought us closer to a future of AI full of potential.
What is GPT?
The GPT (Generative Pre-trained Transformer) model is a neural network architecture that uses the transformer architecture for natural language processing. The GPT model was developed by OpenAI and trained on large datasets of English language text to understand and predict natural language.
GPT is a transfer learning-based model, meaning it is pre-trained on a large dataset and can then be fine-tuned for specific tasks. GPT uses the transformer architecture to learn how to map input sentences to output sentences by predicting the next word in the text sequence.
GPT has been used in various applications, including text generation, text summarization, machine translation, and automatic question answering. GPT-3, the latest version of the GPT model, has achieved impressive results in natural language processing challenges and is considered a major breakthrough in the field of artificial intelligence.

How many versions of GPT model are there?
Currently, there are 5 main versions of the GPT (Generative Pre-trained Transformer) model, which are GPT-1, GPT-2, GPT-3, GPT-4 developed by OpenAI, and GPT-Neo developed by EleutherAI. Each version of the GPT model has a different size and is used in many natural language processing applications.
- GPT-1 is the first version of the GPT model introduced in 2018. It was trained on about 40GB of English text from web pages.
- GPT-2 is the next version of GPT introduced in 2019. It was trained on about 1.5TB of English text data and is considered a major breakthrough in the field of natural language processing.
- GPT-3 is the official version of the GPT model used in the current ChatGPT application, released in 2020. It was trained on about 175 billion parameters and is considered one of the biggest advances in the history of artificial intelligence. GPT-3 can perform many different natural language processing tasks without requiring additional fine-tuning.
- GPT-4 is the latest version of the GPT model, introduced by OpenAI in early 2023. GPT-4 has not been officially released, it is still in development and available for testing for ChatGPT Plus users. It is a large multimodal model that accepts both image and text input and generates text output.
- GPT-Neo is a version of GPT developed by EleutherAI, an independent artificial intelligence research group, and trained on large datasets but not those of OpenAI. GPT-Neo is a free and open-source version of the GPT model.
In addition, there is also a GPT-3.5 version, which is an intermediate version between GPT-3 and 4. It is updated with a larger machine learning database and tested features before the official upgrade to GPT-4.
What’s new in OpenAI’s GPT-4 model?
What is the GPT-4 model?
The GPT-4 model is the latest upgrade to date from OpenAI. It is still in development and limited testing phase. To try out the new features of GPT-4, users must upgrade to a ChatGPT Plus account. If you do not have a ChatGPT Plus account, you can refer to the account upgrade services below:
Returning to the GPT-4 model, it is the latest milestone in OpenAI’s efforts to expand the scale of deep learning. GPT-4 is a large multimodal model that accepts both text and image inputs and outputs text. Although it still lacks the ability to process like a human in many real-world scenarios, it exhibits human-level performance on many technical and academic standards.
What’s new in OpenAI’s GPT-4 model?
GPT-4 can solve difficult problems with higher accuracy thanks to broader general knowledge and problem-solving abilities. Notable new upgrades in the GPT-4 model include:
- GPT-4 is more creative and user-friendly: It can create, edit, and collaborate with users on technical and creative tasks, such as composing songs, writing scripts, or learning a user’s writing style.
- GPT-4 surpasses ChatGPT in advanced reasoning skills.
- GPT-4 outperforms ChatGPT by scoring higher approximate percentages among test participants.
- GPT-4 is safer and more suitable. GPT-4 has a lower rate of responding to disallowed content requests than GPT-3.5, and a higher rate of providing realistic responses.
- GPT-4 can accept images as input and create captions, classifications, and analyses.
- GPT-4 can process over 25,000 words of text, allowing for use cases such as long-form content creation, extended conversations, and document search and analysis. Controlability in GPT-4: Instead of ChatGPT classic personality traits with fixed length, tone, and style, developers can define their AI’s style and tasks by describing those directions in a “system” message via API.
Limitations of GPT-4:
- Lack of specialized knowledge: Despite being trained on a large amount of data, GPT-4 cannot possess extensive specialized knowledge in all areas of human life.
- Lack of interpretability: GPT-4 is a complex deep learning model and not easy to interpret its decisions. This can make its results difficult to understand and explain.
- Impact of input data: Despite being trained on vast data, the input data may not be sufficient or diverse enough, causing GPT-4 to misunderstand or produce unreliable results.
- Language issues: GPT-4 may produce text with good quality, but it may still lack naturalness and may contain redundancy.
Frequently Asked Questions about GPT-4:
When will GPT-4 be released?
GPT-4 was announced by OpenAI on March 14, 2023, but it is still in development and not yet an official upgrade. Currently, ChatGPT still uses data sources from GPT-3 with additional improvements from GPT-3.5.
Is GPT-4 free?
Currently, GPT-4 is still in the testing phase and may be available for free but limited use, only for developers or partners of OpenAI. For individual users, OpenAI has allowed trial use for customers with ChatGPT Plus accounts.
Where can I try GPT-4?
If you are using a ChatGPT Plus account, you can experience GPT-4 right away. When you access the chatbot interface, a dialog box will appear for you to choose “Try GPT-4”. For normal ChatGPT users, the GPT-4 model is not yet supported. You can upgrade your ChatGPT account to ChatGPT Plus here to try it out.
Conclusion:
Although not yet officially released, GPT-4 with its powerful upgrades shows a great step forward in AI and machine learning technology. The future will surely see new upgrades like GPT-5, 6, … more refined in terms of data and natural language. However, no matter how far AI develops, it can never replace human beings. Feedback information from GPT should be used for reference and with careful selection.
