1. Introduction

ChatGPT is a state-of-the-art language model that has revolutionized natural language processing by generating human-like text with context and coherence, enabling new possibilities for human-AI interaction [1]. Its impressive performance in various language tasks and benchmarks has established it as one of the leading language models in the world [2]. ChatGPT’s advanced language modeling capabilities have the potential to transform the way we interact with computers and machines by enabling more natural and intuitive communication [3]. Pre-training on massive amounts of text data has equipped ChatGPT with the ability to understand the nuances of language and generate highly accurate responses, even in complex and ambiguous contexts [4]. Additionally, ChatGPT’s ability to learn from both structured and unstructured data makes it a highly flexible and versatile conversational AI tool [5]. Its advanced neural architecture allows it to handle multiple inputs and generate highly personalized responses, leading to a more engaging and satisfying user experience [6].

Moreover, ChatGPT’s ability to learn and adapt to user preferences and conversational styles over time makes it a highly effective tool for building long-term relationships with customers and clients [7]. ChatGPT’s ability to generate coherent and contextually relevant responses in multiple languages has the potential to break down language barriers and promote cross-cultural communication [8]. Its impressive performance in generating creative and novel text has opened up new possibilities for applications in fields such as creative writing, marketing, and advertising [9]. Finally, ChatGPT’s ability to generate highly realistic and convincing conversational responses can transform the way we learn, interact, and communicate with each other in the digital age [10].

ChatGPT was developed through a two-phase process involving unsupervised pre-training followed by supervised fine-tuning [4]. During the pre-training phase, the model was trained on a massive corpus of text utilizing unsupervised learning techniques, including language modeling and masked language modeling. The primary objective of this phase was to enable the model to acquire a comprehensive understanding of the structure of natural language and the complex interrelationships between words and sentences.

Following the pre-training phase, the model was subject to fine-tuning various downstream tasks such as text completion, question-answering, and dialogue generation. The fine-tuning process encompassed the model’s training on labeled datasets comprising task-specific input-output pairs. The model’s parameters were iteratively adjusted to minimize the discrepancies between the model’s predicted outputs and the proper labels for the given tasks [11].

The outcome was a versatile language model that could proficiently execute diverse natural language processing tasks and generate human-like responses to user inputs [4]. ChatGPT has undergone extensive training on a substantial corpus of data and encompasses many parameters that contribute to its exceptional performance on numerous benchmarks evaluating natural language processing.

ChatGPT is a generative AI model that utilizes deep learning methods to process and produce natural language text. Initially launched as a prototype on 30 November 2022, it became available to the public on 30 January 2023 [12]. The model is trained on vast amounts of text data, enabling it to capture human language patterns, nuances, and complexities. The training corpus includes various sources, such as books, articles, reviews, online conversations, and human-generated data, allowing the model to engage in non-trivial dialogues and provide accurate information on diverse topics [13]. By leveraging the GPT (Generative Pretrained Model [14]) as its foundation, ChatGPT not only expands upon its predecessor but also illuminates a promising trajectory for future research endeavors within this field.

The core advantages of such extensive language models are their ability to understand the context of a given input and produce the correct output [15]. This improvement is significant compared to earlier models because earlier models could not interpret the context of the piece of text. Additionally, the text generated by GPT models is of high quality and is difficult to distinguish from human text. The model can provide answers to questions that cannot be obtained from a search on the web. The responses can also be trusted because the model has been trained from extensive input data [13].

2. ChatGPT Training Process

ChatGPT is a sophisticated large-scale, pre-trained language model developed by OpenAI. It has performed exceptionally on various natural language processing tasks, from language modeling and classification to text generation [12]. The success of ChatGPT stems from its unique training process, which involves using a large amount of unlabeled text data and an innovative training algorithm strategically designed to optimize the model’s capacity to generate coherent and contextually suitable responses to natural language input.

ChatGPT was introduced in November 2022, and its primary purpose is to provide accurate responses to users’ questions. As mentioned, it consists of different deep learning and reinforcement algorithms trained in the content of over 150 billion human-generated items, such as books, articles, blog posts, conversations, and reviews [16]. The platform has one million users and counting in just the first week, and it came out as an emerging technology in AI and natural language processing [17].

The foundation of ChatGPT goes back to the development of GPT, an AI language model developed by OpenAI in 2018. GPT was designed to guess the next word or complete a sentence in a human-generated text, and an immense number of human-generated texts trained its model. The technology was considered a successful and handy tool for several applications, including machine learning, language generation, text prediction in smartphone typing, and many more.

The OpenAI API utilizes various models with distinct capabilities. Among these models, GPT-3.5 is an upgraded version of GPT-3 and can comprehend and produce natural language and code. Meanwhile, DALL·E is a model that generates and modifies images based on a natural language input [18]. On the other hand, Whisper is a model that converts audio to text [19]. Embedding is a model group that transforms text into a numerical representation [20]. Codex is a collection of models that can interpret and produce code, including translating natural language into code [21]. Additionally, Moderation is a fine-tuned model that identifies potentially sensitive or unsafe text [22]. Lastly, GPT-3 is a set of models that can both comprehend and produce natural language [23].

OpenAI’s models have applications in both research and production for developers. The GPT-3.5 series comprises a suite of models trained on a heterogeneous amalgam of text and code data predating Q4 2021. The code-DaVinci-002 model is primarily suitable for tasks that require pure code completion. Meanwhile, the text-DaVinci-002 model is an InstructGPT model that builds upon the code-DaVinci-002 model. Finally, the text-DaVinci-003 model advances upon the text-DaVinci-002 model [24].

This chapter presents an extensive exposition of the ChatGPT training process. The discussion entails the essential constituents of the training process, encompassing the model’s architecture, text data pre-processing, and training algorithm.

2.1. The Architecture of the Model

The ChatGPT model’s architecture design is grounded in a transformer-based neural network, expressly crafted to manipulate and generate natural language text. The transformer architecture, introduced by Vaswani et al. in 2017 [25], constitutes the state-of-the-art methodology for accomplishing natural language processing tasks.

The transformer architecture is renowned for its aptitude for apprehending extended-range dependencies in text data, which is indispensable for tasks such as language modeling and text generation [25]. The architecture embodies a series of transformer blocks, each encompassing a self-attention mechanism alongside a feedforward neural network. The self-attention mechanism confers the model with the faculty to focus on diverse parts of the input text. At the same time, the feedforward network enables the model to comprehend non-linear correlations between the input and output [26].

The ChatGPT model employs a specific variant of the transformer architecture known as the GPT-2 architecture, as introduced by Radford et al. [4] in 2019. The GPT-2 architecture is a multi-layer transformer model that features a large number of parameters, enabling it to capture complex relationships between the input and output [25]. The ChatGPT model, a variant of the GPT-2 architecture, possesses an even more significant number of layers and parameters, enhancing its potency and enabling it to generate highly realistic and coherent responses to natural language input.

2.2. Pre-Processing of Text Data

The pre-processing of text data constitutes a critical aspect of the ChatGPT training process as it plays a significant role in determining the quality and suitability of the input data for the model [27]. To this end, the pre-processing stage of text data for ChatGPT involves a sequence of procedures comprising tokenization, subword encoding, and data cleaning.

• Tokenization is a fundamental step in natural language processing that involves segmenting text into discrete units of meaning, known as tokens [27]. The purpose of tokenization is to facilitate the subsequent processing of text by the model. In the case of ChatGPT, tokenization is performed using a pre-trained tokenizer designed explicitly for natural language processing tasks. This tokenizer converts the input text into a sequence of tokens, where each token represents a specific word or subword unit. The resulting token sequence is then used as input for the model in further processing.
• Subword encoding is a widely used technique in natural language processing to handle rare or out-of-vocabulary words in the input text. It involves breaking down the input text into smaller units or subwords, which the model can then process. Subword encoding has been shown to improve the performance of language models on various natural language processing tasks. In the case of ChatGPT, subword encoding is performed using a pre-trained subword encoder, such as the Byte Pair Encoding (BPE) algorithm, specifically designed for natural language processing tasks [27,28].
• Data cleaning is a crucial step in pre-processing text data as it aims to eliminate irrelevant or noisy information from the input text, ultimately improving the quality and suitability of the input data for the model [29]. It involves a series of steps, such as removing punctuation, numbers, and special characters and correcting spelling and grammatical errors, among others. Data cleaning transforms the input text into a more coherent and standardized form, thereby enhancing the model’s ability to capture meaningful patterns in the data.

2.3. Training Algorithm

The ChatGPT training algorithm employs a variant of the unsupervised pre-training technique based on transformer-based language modeling [25]. The model is trained to predict the next word in a text sequence, with the preceding words serving as input. This objective is accomplished by minimizing the anticipated word’s negative log-likelihood, given the preceding words’ contextual information. The training process comprises essential steps such as initialization, pre-training, and fine-tuning, which are critical in optimizing the model’s performance.

The initialization phase of the ChatGPT training algorithm involves the random assignment of weights to the transformer-based neural network. The weights are initialized based on a normal distribution with a mean of zero and a standard deviation of 0.02, following the recommendations of the GPT-2 paper [4].

2.3.1. Pre-Training Phase

In the pre-training stage, the transformer-based neural network is trained on a large corpus of unlabeled text data to learn general features and patterns of natural language. The pre-training process involves two stages: unsupervised and supervised [27]. The former consists of training the model on unlabeled text data using the transformer-based language modeling approach. The latter involves fine-tuning the model on a smaller corpus of labeled data for specific natural language processing tasks, such as text classification or question answering. Both stages aim to enhance the model’s performance in generating coherent and contextually appropriate responses to natural language input.

The pre-training process utilizes the Adam algorithm, a variant of stochastic gradient descent, to update the model weights more efficiently and stably [30].

2.3.2. Fine-Tuning Phase

The fine-tuning step in the training process of ChatGPT involves further optimizing the model’s performance on specific natural language processing tasks by training it on a smaller corpus of labeled data. This step typically involves several vital processes, including data preparation, architecture modification, and parameter optimization [31].

During the data preparation process, the labeled data undergoes the same pre-processing steps as the unlabeled data, including tokenization, subword encoding, and data cleaning [27]. The model’s architecture may be modified to better suit the specific task at hand, such as by replacing the final layer with a softmax layer for classification tasks [4]. The model’s parameters are then optimized using the Adam algorithm to minimize the loss function of the specific task [30].

During fine-tuning, the model is trained on a smaller dataset of labeled data tailored to the particular natural language processing task. This ensures that the model’s performance is optimized for the specific task while preserving its capacity to generate relevant and meaningful responses to natural language input [31].

.

Bellow, the authors offer a condensed summary of their observations, with a research and programming emphasis, subsequent to their utilization of ChatGPT.

• Research: Observations gleaned from the utilization of ChatGPT suggest that the platform can identify and proffer academic references that pertain to specific sentences or paragraphs, thereby facilitating the work of prospective researchers in their search for relevant sources. However, it was noted that most of the proposed references, while related to the topic, must be more present in academic databases and often feature errors in author names or digital object identifiers (DOIs). Following the identification of such errors, ChatGPT endeavored to rectify the situation by suggesting alternative sources, but these, too, were found to be erroneous upon scrutiny. In response to these repeated instances of inaccuracy, ChatGPT expressed regret at its inability to offer suitable alternatives. The genesis of this particular issue could be attributed to an error that occurred during the training phase of the model, an anomaly that the developers have yet to uncover. Ultimately, it is imperative to emphasize that researchers should exercise extreme caution and refrain from relying solely on tools such as ChatGPT to procure references to pertinent scholarly articles.
• Programming: In an attempt to confirm the rumors about the programming proficiencies of ChatGPT, the researchers provided the platform with a prompt describing the desired program features. The output in the Python programming language was remarkable. However, it was observed that composing an appropriate prompt effectively conveying the desired request to ChatGPT necessitates a certain degree of programming knowledge. Furthermore, while the output was impressive, comprehending and adapting it to meet the specific demands of a project also requires programming expertise. To summarize, ChatGPT can be a valuable tool in aiding developers in the generation of code, but it cannot supplant the developer’s role, at least not at present.

Subsequently, some key authors’ thoughts and concerns regarding ChatGPT are succinctly deliberated through pressing queries.

• To what extent will the advancement of science be expedited and streamlined by empowering scientists with instantaneous access to information by posing relevant queries to ChatGPT?
• The primary objective of this research is to generate knowledge for future applications. However, the process of a new scientist gathering information from existing literature and using it to expand the field can lead to significant delays in time. While this time is not necessarily wasted, it may impede the discovery of fresh ideas that could more expeditiously solve pressing human problems. AI tools, such as ChatGPT, could enable new scientists to read the fundamental concepts of a field and pose pertinent questions within a few hours. Nevertheless, AI tools must evolve to offer knowledge commensurate with the level of expertise expected by scientists. In this vein, neophyte scientists could commence the development of the technology from the outset, drawing upon prior research in the field. A compelling example of this pertains to the potential acceleration and efficiency with which novel medical treatments can be devised for emerging diseases.
• Does the continued existence of search engines, as we have known them thus far, remain justified?
• To date, the conventional approach to utilizing search engines has involved posing search queries and awaiting the corresponding search results. Subsequently, individuals browse through a plethora of websites suggested by search engines in hopes of obtaining the requisite knowledge. Yet, how often have we altered the search term (i.e., keyword) due to unrepresentative outcomes? The advent of AI tools such as ChatGPT will transform the conventional search methodology. By conversing with the AI tool and enabling it to filter information on our behalf, the most suitable outcomes will be instantly accessible without any time wastage (Microsoft Bing: Reinventing search with a new AI-powered). Nonetheless, it is critical to underscore that the searcher’s capacity for critical thinking is likely to be significantly reduced.
• Does the emergence of ChatGPT and other AI tools signal the demise of eCommerce as we know it today?
• The integration of ChatGPT and other AI tools into eCommerce platforms may disrupt the traditional way of online shopping. Previously, consumers reached online stores through search engines or third-party platforms, selecting products that align with their needs using built-in eCommerce filters. However, with the integration of ChatGPT in searches, specific products, and online stores may be suggested, which may not necessarily be the most cost-effective or highest-quality options. There is a potential threat of specific recommended products being prioritized to bring more significant benefits to the company that created the AI tool. As such, the introduction of AI tools in eCommerce platforms raises concerns about the potential impact on consumer choice and the overall integrity of the online shopping experience.
• To what extent will individuals utilize ChatGPT or comparable AI tools for disease diagnosis and treatment?
• Although ChatGPT does not provide direct answers to such inquiries, numerous articles, particularly in online publications, promote the use of ChatGPT as a tool capable of delivering answers that can aid in diagnosing a disease or even providing treatment. The authors of some articles have asked ChatGPT about diagnosing and treating diseases. Even though the OpenAI FAQ clearly states that cure or treatment questions violate the terms of use [78], ChatGPT provides treatment-related information. To maintain objectivity, the following statement was appended to the response: “It is important to talk to a healthcare professional. Your healthcare provider can help you determine the best treatment option for your specific needs”. Nonetheless, ChatGPT has the potential to be a promising technology for identifying diseases in their early stages through symptoms before they become advanced. Therefore, both humans and AI tools should exercise caution when reading and responding to the results. Specifically, for disease prevention, similar technologies could prevent disease progression by identifying symptoms and referring patients to a doctor.

In summarizing the results of our study, it is evident that ChatGPT offers both benefits and drawbacks across a range of domains. Notably, in the fields of healthcare and research/science, ChatGPT can enhance productivity and efficiency. Furthermore, ChatGPT can assist with educational and programming endeavors. However, ethical concerns and uncertainties surrounding potential job displacement are among the negative consequences that arise from this technology. As such, governments need to establish regulatory frameworks to mitigate any adverse effects that may occur from the adoption of ChatGPT. Ultimately, this technology can potentially revolutionize existing domains, ranging from positive to negative.
