Developed by OpenAI, ChatGPT has become a global phenomenon with its impressive natural language processing capabilities. From GPT-1 with 117 million parameters to GPT-4o with more than 1 trillion parameters, ChatGPT has undergone a strong development journey, creating breakthroughs in many fields.

Development history: from the beginning to the great breakthrough

The idea of ​​machines that can think like humans has been around since the 1950s. However, it was not until recent years, with the explosion of technology and big data, that artificial intelligence (AI) emerged. really growing strongly.

In 2018, OpenAI introduced GPT-1, the first version of Generative Pre-trained Transformer. With 117 million parameters, GPT-1 has achieved a breakthrough in the field of natural language processing (NLP). It is capable of learning from huge amounts of text data, producing natural and coherent text.

By 2019, OpenAI continued to release GPT-2 with 1.5 billion parameters, many times more than GPT-1. GPT-2 possesses the ability to process data and create more complex documents, demonstrating outstanding power. OpenAI has been cautious in releasing GPT-2's source code due to concerns about the technology's potential for abuse.

A year later, OpenAI introduced GPT-3, a spectacular step forward with 175 billion parameters. GPT-3 became one of the largest and most powerful AI models ever developed. It is capable of producing extremely natural and convincing texts, from writing essays, answering questions to composing poetry, opening up a wide range of application potential.

In 2023, GPT-4 is born with 1 trillion parameters, marking a new breakthrough. Not only is GPT-4 more powerful, it also has better contextual understanding, reduces errors, and provides more accurate answers. GPT-4 also integrates many languages ​​and in-depth knowledge, improving user experience. 

On May 13, 2024, OpenAI introduced GPT-4o, a special version optimized to interact with humans in the most natural way. GPT-4o has more than 1 trillion parameters, more powerful than previous versions. GPT-4o is integrated into many practical applications such as chatbots, virtual assistants and consulting systems. With its deep learning capabilities and sophisticated contextual understanding, GPT-4o has become an indispensable tool in many fields.

The future is promising: ChatGPT and its continued progress

ChatGPT's underlying technology is Transformer, a deep learning model specializing in natural language processing. Transformer was first introduced in 2017 by Google Brain and has become the core technology for many modern AI models. Transformer allows the model to learn from text data efficiently and generate new text naturally and coherently. 

As of 2024, the market value of OpenAI, the company that develops ChatGPT, is estimated to be in the tens of billions of dollars. ChatGPT quickly became popular thanks to its powerful natural language processing capabilities and wide application in many fields. Partnering with major companies like Microsoft to integrate ChatGPT into products like Microsoft Office and Azure has significantly contributed to this popularity.

OpenAI offers ChatGPT in two forms: free and premium. Free users get access to ChatGPT's basic features, which can be used for simple tasks like answering questions, writing basic content, and helping with everyday tasks. Premium users (ChatGPT Plus) for $20/month receive additional benefits such as: faster access, priority usage during peak hours, access to the latest features and updates.

In addition to natural language processing, OpenAI has also developed AI models capable of generating images from text, such as DALL-E. This ability allows users to create creative and complex images based on text descriptions, opening up many applications in design, advertising and art.  From customer support, teaching to content creation, ChatGPT has demonstrated its wide applicability and potential in many fields. 

ChatGPT's development does not stop here. OpenAI and other companies are continuing to research and develop upgraded versions with greater capabilities and accuracy. New applications of ChatGPT will continue to be discovered, from healthcare, legal advice to daily work support.

ChatGPT is one of the outstanding achievements of artificial intelligence in the past decade. With the continuous advancement of technology, ChatGPT will continue to develop and bring more benefits to society. However, clear regulatory and ethical measures are needed to ensure that this technology is used for its intended purpose and brings the best benefits to humans.
