1. Introduction
ChatGPT is a sophisticated chatbot developed with OpenAI. It is based on the GPT (Generative Pre-Trained Transformer) language model technology and is capable of understanding and interpreting user requests and generating appropriate responses in natural human language, allowing it to complete a wide range of text-based tasks such as answering questions and generating responses. It is a significant innovation in NLP and artificial intelligence. OpenAI, a research laboratory founded in 2015, has gained significant support and investment, allowing it to make rapid progress in the development of AI technologies, including other products such as DALL-E. GPT, the technology on which ChatGPT is based, is a language model that uses a combination of generative and discriminative techniques to produce responses indistinguishable from natural human language, by learning from vast amounts of data, including the entire internet. This technology has the potential to greatly reduce the time required for research tasks and may potentially render traditional research authors obsolete [1].
ChatGPT has shown impressive results on various benchmark datasets and has been widely adopted in various natural languages processing applications such as chatbots, dialogue systems, and text generation. The remarkable performance of ChatGPT has sparked a renewed interest in the field of language models and their potential to revolutionize the way we interact with machines. Interestingly, ChatGPT is a powerful tool for various NLP tasks, including language translation, question answering, text completion, and more [2]. ChatGPT’s massive size and advanced training techniques have also allowed it to demonstrate a level of general knowledge and reasoning abilities that were previously unseen in language models [3,4].
In this study, we aim to provide a comprehensive overview of ChatGPT, its strengths, limitations, and future implications.

2. Related Work
ChatGPT is a powerful language model that has been used for text generation in many different fields. Researchers have used ChatGPT to create text content that is relevant and coherent for specific industries [6], such as healthcare [7], tourism [6], and future development [8]. ChatGPT’s versatility has led to innovative research and new applications in the real world [9,10].
In the paper [11], the authors highlighted some of the concerns in using large language models (LLMs) like ChatGPT. LLMs have the potential to revolutionize research methods, but there are also concerns about the quality, accuracy, and transparency of research outcomes that could be generated using LLMs. LLMs may contain errors, biases, and plagiarism. Additionally, LLMs may replicate and amplify the cognitive biases of the humans who train them. This means that there is a risk that LLMs could be used to generate inaccurate, biased, or plagiarized research.
The authors of the text provide guidance for researchers who use LLMs. They emphasize the importance of recognizing and mitigating the potential risks associated with using LLMs. This includes carefully validating the information generated with LLMs, ensuring accuracy, and meticulously assessing the sources behind the content. The authors conclude by stating that careful scrutiny is essential to preserve research integrity amidst the transformative capabilities of LLMs.
The authors explored the implications of using ChatGPT in the tourism industry [6], with a focus on striking a balance between convenience and challenges. The study’s findings, based on interviews with professionals from various fields within the tourism industry, provide a comprehensive perspective. The integration of ChatGPT into the tourism industry presents a complex picture, with both convenience and challenges.
In the paper [8], the authors studied how ChatGPT is changing scientific research, including data processing, hypothesis generation, collaboration, and public outreach. They looked at potential problems and ethical questions when using ChatGPT in research, emphasizing the need to balance AI-driven innovation with human knowledge. The authors discussed ethical issues in various computing fields and how ChatGPT can pose challenges. They also pointed out biases and limitations of ChatGPT. Despite controversies, ChatGPT has gained attention in academia, research, and industry in a short time.
Another paper examined the accuracy of the content generated with ChatGPT in healthcare [7]. The results showed that most of the content was useful in some way, but that all statements provided should be checked more carefully. ChatGPT is a narrative LLM for medical personnel.
3. An Overview of ChatGPT
Three different versions of GPT, i.e., GPT-1, GPT-2, GPT-3, and GPT-4 were released by OpenAI in the past. The four versions of GPT differ in size. Each new version was trained by scaling up the data and parameters. Table 1 shows the different parameters used by the three versions of GPT and the different features each version supports [12,13].
ChatGPT was developed on top of the GPT-3 language model using reinforcement learning from human feedback (RLHF). The initial model was trained using supervised fine-tuning, where human AI trainers participated in conversations, playing both the role of the user and an AI assistant. The trainers were provided with model-generated suggestions to assist them in composing their responses. ChatGPT and InstructGPT are both variants of the GPT language model, but they have different focuses and training data. InstructGPT is specifically designed for generating instructional text and providing step-by-step guidance, while ChatGPT is a more general-purpose conversational AI model that can be used for a variety of text-based tasks.
A new dialogue dataset was created by combining the InstructGPT dataset, which was transformed into a dialogue format, with other dialogue data. This new dataset was used to fine-tune both ChatGPT and InstructGPT, allowing them to perform better in dialogue-based tasks. Overall, while both models are based on the GPT architecture, they have different strengths and use cases. InstructGPT is ideal for tasks that require providing detailed instructions, while ChatGPT is better suited for generating natural language responses in conversational settings.
ChatGPT uses reinforcement learning to fine-tune the model, and the data are collected for comparison, consisting of multiple model responses ranked by quality. The data are gathered from conversations between AI trainers and the chatbot. The trainer selects a randomly selected model-generated message, samples, and ranks during this process. Using reward models, it is fine-tuned by using Proximal Policy Optimization, and the process is repeated several times [14]. Figure 1 shows the basic model used to train ChatGPT, and the steps are listed as follows:
-
The input layer takes in a sequence of words and converts them into numerical representations called embeddings. The embeddings are passed to the transformer layers.
-
The transformer layers are made up of multi-head self-attention mechanisms and feed-forward neural networks. The self-attention mechanisms allow the model to focus on specific parts of the input when generating a response, while the feed-forward neural networks allow the model to learn and extract features from the input.
-
The transformer layers are stacked on top of each other and are connected through residual connections. This allows the model to learn and extract features at different levels of abstraction.
The GPT models are built on Google’s transformer architecture, which was introduced in 2017 through the paper “Attention is all you need” [15]. Within the field of natural language processing (NLP), researchers have explored various algorithms to address challenges in human language, including morphological variations, synonyms, homonyms, syntactic and semantic ambiguity, co-references, pronouns, negations, alignment, and intent. While earlier computational linguistics methods (such as grammatical, symbolic, statistical approaches, and early deep-learning models like LSTM) faced limitations in resolving these issues, transformers emerged as a successful solution.
Transformers, specifically through their advanced mechanism called multi-head self-attention, have demonstrated the ability to automatically detect and handle many linguistic phenomena mentioned above. This capability is a result of being exposed to vast amounts of human language data.
The original transformer architecture consists of an encoder and a decoder, which effectively handle complex sequence-to-sequence patterns involving both left- and right-side context sensitivity—common in natural language. Both the encoder and decoder comprise multiple feed-forward layers that employ the self-attention technique mentioned earlier. The number of these layers typically ranges from 12 to 24, depending on the model’s complexity and can go up to 128 in the largest GPT-4 model. These layers have been proven to be able to capture various levels of linguistic ambiguity and complexity, encompassing punctuation, morphology, syntax, semantics, and more intricate interactions. Essentially, by being exposed to language data, these models swiftly learn the essential components of the standard NLP pipeline. ChatGPT can be used for a wide range of applications, as shown in Table 2.
These are just a few examples of the many possible applications of ChatGPT where it can be useful [1,16]. However, there are several limitations of ChatGPT, as given in Table 3.
4. A Comparative Study of ChatGPT and Other Language Generation Models
Language generation models are an important area of research in the field of NLP. For example, ChatGPT can generate human-like text and perform a variety of NLP tasks. However, it is not the only model available for language generation. Other models such as GPT-2, GPT-3, BERT, RoBERTa, T5, XLNet, Megatron, and ALBERT have also been developed and have shown good performance in language generation and other NLP tasks [17]. Many studies have been conducted to compare the performance of various language models, including ChatGPT [18].
There are several research studies with an emphasis on language processing models and differences in the quality of outputs. A recent comparative study of GPT-2 and GPT-3 language models by researchers at the Indian Institute of Technology compared the performance of GPT-2 and GPT-3 [19]. The study looks at the quality of the language generated with the two models, as well as their ability to complete a variety of NLP tasks. The study concludes that GPT-3 outperforms GPT-2 in terms of language generation quality and task completion accuracy.
Another study that may be relevant is a comparative study of GPT-3 and BERT language models [20,21]. This study compared the performance of GPT-3 with BERT, which is another state-of-the-art language model developed by Google [22]. The study looked at the ability of the two models to complete a variety of natural language understanding tasks and concluded that GPT-3 outperforms BERT in many cases [23], but BERT is better in certain tasks such as named entity recognition [24]. Here are a few examples of tasks where GPT-3 has been found to outperform BERT in the scope of these relevant studies:
Language generation: GPT-3 has been found to generate more fluent and natural-sounding language than BERT in several studies. This is likely due to GPT-3’s larger model size and training data, which allows it to capture more nuanced relationships between words and phrases [23].
Question answering: GPT-3 has been found to be more accurate than BERT in answering questions based on a given context. This is likely due to GPT-3’s ability to generate text, which allows it to provide more detailed and informative answers [25].
Text generation: GPT-3 has been found to generate more coherent and coherently written text than BERT in several studies. This is likely due to GPT-3’s ability to generate text, which allows it to generate more complete and well-formed sentences [26].
Text completion: GPT-3 has been found to be more accurate than BERT in completing the text, especially in the case of long-form text such as articles and essays [27].
Summarization: GPT-3 has been found to generate more fluent and informative summaries than BERT in several studies. This is likely due to GPT-3’s ability to understand and analyze the content of a text, which allows it to generate more accurate and informative summaries [13,28].
Sentiment analysis: GPT-3 has been found to be more accurate than BERT in determining the sentiment of text, such as whether the text expresses a positive, negative, or neutral sentiment [29].
Text classification: GPT-3 has been found to be more accurate than BERT in classifying text into different categories, such as news articles, social media posts, and customer reviews [30].
Dialogue systems: GPT-3 has been found to be more accurate than BERT in generating natural and coherent responses in dialogue systems such as chatbots [31].
It is important to note that while GPT-3 has been found to outperform BERT in many cases, BERT is better in certain tasks such as named entity recognition, which is a task of identifying and classifying named entities in a given text [32].
Table 4 provides a comparison of popular language models based on various criteria such as model name, training data, model size, structure, performance, advantages, and disadvantages. The table includes information on models such as GPT-2, GPT-3, GPT-4, BERT, RoBERTa, T5, XLNet, Megatron, and ALBERT. It shows the amount of data used to train the model and the number of parameters, the structure of the model, and its performance on certain tasks. It also highlights the advantages and disadvantages of each model, such as computational cost, memory requirements, and ease of fine-tuning. Table 4 can be used as a reference for choosing the appropriate model for a particular task and to understand the trade-offs between the different models [33].
Figure 2 compares the performance of GPT-2, GPT-3, BERT, RoBERTa, T5, XLNet, Megatron, and ALBERT on text classification, text generation, and text summarization tasks. The figure lists the name of the language model in the horizontal line and the performance of each model on different tasks in the vertical line. The performance is presented as a percentage and ranges from 0 to 100%.
According to this Figure 2, GPT-3, XLNet, and Megatron have the highest performance across all tasks, with average performance of 95%, 90%, and 92%, respectively. While GPT-2, BERT, RoBERTa, and T5 have similar performances, with average performance of 85%, 85%, 85%, and 87%, respectively, and ALBERT has the lowest performance, with an average performance of 89% [34].
The performance percentages show how well the language model performed on each task. We evaluated the model by asking it to classify, summarize, and generate text. Human judges assessed the results based on accuracy, fluency, and coherence. The evaluation was quick and simple, using a metric of simplicity.
GPT-4 is a powerful language model that can process text, photos, and videos. This makes it a versatile tool for marketers, organizations, and individuals alike. GPT-3, on the other hand, is better at processing language but struggles with complex multimedia inputs like video. GPT-4 is also better at understanding and producing different dialects and reacting to the emotions represented in text. For example, GPT-4 can detect and respond to a user expressing sadness or anger in a way that feels more intimate and sincere. GPT-4’s ability to handle dialects is one of its most impressive features. Dialects are local or cultural variants of a language, and GPT-4 can understand and produce them with ease.
Another advantage of GPT-4 is its ability to synthesize data from multiple sources to answer complex questions. GPT-3 may have difficulty making connections to answer complex questions, but GPT-4 can easily do so by drawing on information from a variety of sources. In addition to its other strengths, GPT-4 is also capable of producing creative content with greater coherence. For example, GPT-4 can create a short story with a strong storyline and character development, whereas GPT-3 may struggle to keep the narrative consistent and coherent.
Finally, GPT-4 has a maximum token limit of 32,000 tokens, or 25,000 words. This is a significant increase from GPT-3’s maximum token limit of 4000 tokens, or 3125 words. This means that GPT-4 can generate more complex and detailed text than GPT-3.
5. ChatGPT for Dialogue Generation
ChatGPT is an online tool for dialogue generation that uses a transformer architecture and is trained on a massive amount of conversational data to understand and generate human-like text [35]. It can handle a wide range of inputs, generate a wide range of responses, and mimic human-like interactions, making it ideal for a wide range of applications such as chatbots, virtual assistants, and language education.
One of the dialogue generation applications of ChatGPT is in creating chatbots for customer service and support. ChatGPT can be trained on large amounts of customer service data, allowing it to understand and respond to a wide range of customer inquiries. This can improve the efficiency and accuracy of customer service operations, as ChatGPT-powered chatbots can handle a high volume of interactions simultaneously and provide consistent and accurate responses [36].
Another application of dialogue generation OF ChatGPT is in the field of natural language understanding [35,37]. ChatGPT can be trained on a wide range of conversational data, allowing it to understand and respond to a wide range of user inputs. This makes it an ideal tool for building conversational agents, such as virtual assistants and voice-enabled devices. Moreover, ChatGPT could be used to generate dialogue for creative writing, for instance, in writing a script for a movie, TV series, or even a game. It may also be used to generate dialogue for characters and to also simulate different scenarios and different emotions.
In addition, ChatGPT could be used in the field of language education [38], for it could be used to generate dialogues for language learners or to generate dialogues for different levels, different scenarios and different situations.
When using ChatGPT in dialogue generation, there are several challenges and considerations to keep in mind. One of the main challenges is the potential for the model to generate inappropriate or biased responses. This can occur if the model is trained on data that contain biases or if the model is not properly fine-tuned for a specific application. To overcome this challenge, it is important to carefully curate and pre-process the training data and to fine-tune the model on a specific task and domain.
When using ChatGPT in dialogue generation, there are several key considerations to keep in mind. Firstly, the quality and bias of the training data can significantly impact the performance of the model. It is important to ensure that the data are diverse and represent a wide range of perspectives. Secondly, ChatGPT may not be well-suited for a specific application out of the box. Fine-tuning the model on a specific task and domain can help improve its performance. Thirdly, ChatGPT may struggle to handle words that it has not seen during training. Techniques such as subword tokenization can help mitigate this issue. Fourthly, ChatGPT may not always generate text that is coherent or appropriate in a given context. Techniques such as beam search and top-k sampling can help improve coherence and context. Finally, ChatGPT is a large model that requires a significant amount of computational resources to run. This can be a challenge for resource-constrained environments and real-time applications.
6. ChatGPT and Privacy Concerns: An Analysis
As with any form of digital technology, there are potential risks associated with using ChatGPT, particularly in terms of privacy [39,40]. One of the main concerns with ChatGPT is the potential for it to be used to generate sensitive or personal information [41]. Since ChatGPT is trained on a large amount of data, it can potentially generate information that is private or sensitive, such as medical records [40], financial information, or personal details.
One of the potential risks associated with using ChatGPT is the possibility of the model being used to generate sensitive information without the consent of the individuals involved [42]. For example, ChatGPT could be used to generate fake conversations or emails that appear to be from real people, which could be used to commit fraud or impersonate individuals. Additionally, ChatGPT could be used to generate sensitive information such as medical diagnoses or financial transactions, which could be used to exploit individuals or steal their identities [16,43]. The potential for ChatGPT to be used for malicious purposes highlights the need for strong privacy regulations and oversight in the development and use of these models.
Another potential risk is the possibility of the model being used to target individuals with personalized phishing, scams, or other malicious activities. For example, an attacker can use ChatGPT to generate a personalized message that looks like it came from a bank, or from a person the victim trusts, to obtain sensitive information or money from the victim [44]. Furthermore, ChatGPT could be used to generate offensive or fake content, which could be used to spread misinformation or incite violence. To mitigate these risks, it is important to ensure that the data used to train the model are properly protected and that the model is only used for legitimate purposes.
One of the technical concerns with ChatGPT is that it can memorize and reproduce personal information from the dataset it was fine-tuned on. This is because ChatGPT is a neural network with a large number of parameters that allow it to learn patterns from the data. In other words, if the fine-tuning data contain personal information such as credit card numbers, social security numbers, and phone numbers, ChatGPT could potentially generate similar information in its outputs. There have been several reported cases of ChatGPT and other language generation models potentially compromising personal information. Here are a few examples related to ChatGPT:
Researchers at OpenAI found that GPT-3 [45], which is the latest version of ChatGPT, could generate responses that were indistinguishable from the human-written text. They trained the model on a diverse range of internet text and fine-tuned it on specific tasks such as language translation, question answering, and summarization. They found that GPT-3 could perform these tasks with high accuracy, often requiring only a single example to learn the task. This raises concerns about the potential for GPT-3 to be used to create phishing emails or other malicious content that can lead to personal information being compromised.
In another case, the researchers at the AI Ethics Lab found that fine-tuning a language model on a dataset containing personal information [46], such as emails and text messages, can result in the model memorizing and reproducing that personal information. They fine-tuned a version of GPT-2 on a dataset of private emails and found that the model was able to generate private information such as phone numbers and email addresses with high accuracy. These examples serve to highlight the potential risks that arise when utilizing language generation models such as ChatGPT. If these models are fine-tuned using datasets that include sensitive personal information, there is a possibility of compromising data privacy and experiencing a breach.
It is worth noting that these studies highlight the importance of careful curation and pre-processing of training data and the need for appropriate data security measures when fine-tuning the model to ensure that personal information is not compromised. Furthermore, these studies also stress the importance of monitoring and evaluating the model’s performance to detect any potential privacy issues and to take necessary actions [45].
Table 5 provides a brief overview of the technical measures that can be taken to mitigate the risk of ChatGPT generating personal information when fine-tuned on such data. It is worth mentioning that the effectiveness of these measures would depend on the specific use case and the data used, and the best approach to mitigate the risks would be a combination of technical, organizational, and legal measures.
7. ChatGPT and Its Applications in Business and Industry
Despite the concerns surrounding data security and integrity, the value of converging and integrating various forms of Open AI such as ChatGPT has become the focus of emerging research [47,48]. The emergence of ChatGPT as an effective intelligent application capable of generating textual knowledge has sparked a new interest in its creative uses and applications. For example, ChatGPT can be used in customer service by generating responses to frequently asked questions, reducing the workload on human customer service representatives. The same approach might also be used in marketing campaigns by providing product descriptions and advertising material through social media channels.
Furthermore, in the age of disruption and digital space, the creation of timely and relevant content has become a catchphrase of popular and scholarly discourses [49]. To this end, ChatGPT can be used to generate educational material, articles, and creative writing like stories and scripts [50,51]. Coupled with the rapid changes in student demographics, the increasing cost of college education, and the relatively diminished value of an academic degree, ChatGPT may serve as a critical interface for addressing logistical costs and increasing institutional efficiencies. From a pedagogical and andragogical standpoint, ChatGPT can offer today’s learners the individualized and Just-in-Time (JIT) platform for learning and skill development [51]. The benefits of such implementation have been measured and quantified within industrial and business practices. Table 6 shows a sample list of businesses and industries that have benefited from the use of AI to increase efficiency, revenue, and customer satisfaction. While ChatGPT is creating a lively discussion in public and scholarly debates, particularly within the ecology of global higher education, interest in AI as a catalyst for development and a path to innovation has long existed. Table 7 shows the significance of AI investment in increased productivity and long-term economic and environmental sustainability across several sectors of the economy.
The healthcare industry is another potential beneficiary of OpenAI due to the usefulness of applications like ChatGPT in medical education, which uniquely combines theoretical knowledge and hands-on clinical training. Medical students learn the science behind disease and treatment, but they also gain practical experience by engaging with patients and other health professionals. However, medical education is continuously evolving to keep up with technology, treatment options, and governmental regulations. The emergence of ChatGPT becomes ideal for addressing the needs and challenges of medical education. To remain abreast of such changes and to meet licensing requirements, ChatGPT can offer medical students and practicing clinicians with up-to-date information and guidelines within the healthcare field [52,53]. Table 8 shows a sample of ChatGPT applications within medical education and healthcare practice. It is also worth noting that the implementation of AI tools like ChatGPT has many incentives including a relatively high return on investment (ROI). Table 6 shows the potential ROI from investing in AI tools:
8. Training and Fine Tuning ChatGPT for Specific Tasks
Training ChatGPT for specific tasks typically involves fine-tuning the model on a dataset that is relevant to the task. This can be achieved by using the pre-trained weights of the model as a starting point and then training the model further on the new dataset. This process is known as transfer learning and can significantly improve the performance of the model on the specific task. Fine-tuning can be carried out by adjusting the hyper parameters of the model such as the learning rate and the number of training iterations. It is important to have a good understanding of the task and the relevant dataset before fine-tuning the model [54].
Fine-tuning ChatGPT typically involves training the model on a new dataset that is specific to a certain task, such as language translation or question answering. The pre-trained weights of the model are used as a starting point, and the model is then further trained on the new dataset. Algorithm 1 shows the steps needed to fine-tune ChatGPT for specific tasks [54].
| Algorithm 1: Fine-tuning ChatGPT. |
Data: Dataset D, Task T |
Result: Fine-tuned model |
|
In the next sub-sections, we give some examples on specific tasks such as text summarization and question answering.
8.1. Fine Tuning ChatGPT for Text Summarization
Text summarization is the process of using the pre-trained model to generate a shorter version of a given text, while still preserving the most important information from the original text. This is carried out by fine-tuning the pre-trained model on a dataset of texts and their corresponding summaries.
The fine-tuned model can then be used to generate a summary for a new text, by encoding the input text and using the trained model to generate a summary. The generated summary is typically shorter than the original text, but it still conveys the most important information from the original text [13,55].
Text summarization is the process of generating a shorter version of a given text, while still retaining the most important information from the original text. To fine-tune ChatGPT for text summarization [13], the following steps need to be followed:
Firstly, a dataset of text documents and their corresponding summaries should be obtained, which is large enough to ensure effective learning. Then, the dataset should be preprocessed by tokenizing the text and creating input-output pairs for the model. The model should be initialized with the pre-trained weights of ChatGPT, which can be loaded from a checkpoint file that contains the weights of a pre-trained ChatGPT model.
After that, the model should be trained on the new dataset using a suitable fine-tuning technique, such as transfer learning. The model is trained to generate a summary of the input text by providing the model with a pair of input-output, where the input is the text document and the output is the summary of the text document. The hyperparameters of the model, such as the learning rate, the batch size, the number of training iterations, and the maximum length of the input text, should be adjusted to optimize the model’s performance on the specific task.
Once the fine-tuning process is completed, the model’s performance should be evaluated on a test set that is independent of the dataset used for training. Once the model is deemed effective, it can be used to generate summaries for new text documents in a pipeline with other models or in an end-to-end summarization system.
8.2. Fine Tuning ChatGpt for Question Answering
A question-answering application is a system that uses the language model to answer questions based on a given context or a provided dataset. The application takes a question as input and generates an answer based on the patterns learned during training [56].
The ChatGPT is fine-tuned for question answering by training it on a dataset of questions and answers, this is carried out by providing the model with a large dataset of questions and answers and adjusting the model’s parameters to minimize the difference between the model’s predicted answer and the actual answer. The steps to fine-tune ChatGPT for question answering are given as follows [29,57]:
1.. The first step in fine-tuning ChatGPT for question answering is to collect a dataset related to questions and answers. The dataset should be large and diverse and should cover a wide range of topics. It should contain pairs of questions and corresponding answers, and it can be obtained from various sources, such as existing Q&A datasets or by scraping the web for Q&A pairs.
2.. The second step involves preprocessing. This step involves cleaning the data and formatting it in a way that can be used to train the model. This may include tokenizing the text, lowercasing the words, and removing special characters. It also includes splitting the dataset into training and testing sets, so that the model can be evaluated on a held-out set of questions.
3.. In this step, we fine-tune ChatGPT. There are several methods to fine-tune a language model, such as transfer learning, which uses pre-trained models, or fine-tuning from scratch. Transfer learning is useful when you do not have a large dataset, or when you want to fine-tune a pre-trained model for a specific task. Fine-tuning from scratch is useful when you have a large dataset and more computational resources.
4.. This step involves adjusting the model’s parameters to minimize the difference between the model’s predicted answer and the actual answer. This is typically carried out using supervised learning techniques and may involve adjusting the model’s architecture, such as adding an attention mechanism, to improve its performance on the task. The fine-tuning process can be performed using a variety of techniques such as backpropagation, gradient descent, and Adam.
5.. After the model is trained, it is evaluated on a held-out test set to measure its performance and to make sure that it generalizes well to new questions. The evaluation metrics typically used for this task are BLEU, METEOR, ROUGE, and CIDEr.
6.. Based on the evaluation, the model can be fine-tuned further by adjusting its parameters and architecture, or by collecting more data. The fine-tuning process can be repeated until the model reaches a satisfactory level of performance.
7.. Once the model is fine-tuned, it can be deployed in a production environment, such as a website or mobile app, to answer new questions. This involves converting the model to a format that can be easily integrated into an application, such as TensorFlow.js or TensorFlow Lite.
Fine-tuning ChatGPT for question answering is an iterative process that requires a combination of data collection, preprocessing, training, evaluating, and fine-tuning, and it should be tailored to the specific use case and the available resources.
9. Language Generation Quality
ChatGPT is a powerful tool for NLP, and it can help with many tasks, particularly those with high levels of repetition and redundancy, but it is not a replacement for human intelligence. Human intelligence is based on biological processes and thus the ability to understand context, interpret meaning, and make connections. However, ChatGPT is based on ML algorithms, data, and previously entered data [58]. Additionally, to further understand the difference between a text generated by human and that of ChatGPT, it is important to point out the subjective and objective nature of the language and texts produced with ChatGPT and by a human, respectively [59].
In general, a human-generated text is characterized by its ability to convey meaning and intent, which also reflects other aspects of human intelligence (i.e., cultural intelligence CQ, and emotional intelligence EQ). Additionally, a text generated by humans uses figurative language, idiomatic expressions, and cultural references, which varies extensively from one setting to another and from one targeted audience to the next. On the other hand, a text generated with ChatGPT is based on patterns and stored data, thus may struggle to account for and understand cultural and societal contexts. A text generated with artificial intelligence may also contain grammatical, stylistic, and vocabulary errors [58]. A ChatGPT text may not account for or recognize language that is considered exclusive or derogatory based on social norms and other cultural circumstances.
Ways of improving texts and content generated with ChatGPT: The inadequacy and imperfection of ChatGPT in producing natural language that meets the meaningfulness and intentionality of human-generated texts makes it an ideal ecosystem for testing, experimentation, and improvement [54,60]. There are several strategies for enhancing textual content generated with ChatGPT. The accuracy and coherence of text generation depends in part on the level of fine-tuning of the dataset as the source of the desired language [54]. Another strategy for improving the quality of AI generated texts is by combining different models, thus averaging the predictions of outcomes. Finally, post-processing might be used to adjust and edit based on the desired writing, social, and cultural contexts.
10. Evaluating the Performance of ChatGPT on Different Languages and Domains
ChatGPT is trained on a variety of text databases such as Common Crawl [61], WebText2 [62], Wikipedia, Books1 and Books2 [63], etc., so it is able to understand and generate text in a variety of languages. However, it is primarily designed to understand and generate text in English. ChatGPT is able to communicate in multiple languages. Indeed, it uses a deep learning model known as a transformer architecture [15], which is a neural network-based language model that has demonstrated success in natural language processing tasks. The model can learn the patterns and structures of multiple languages because it has been trained on a big corpus of text data in many different languages. Comprehending the underlying grammatical and semantic rules of each language enables the model to generate human-like text in a variety of languages.
The model can be adjusted to function in certain languages or dialects and can handle a variety of input formats, including text, speech, or graphics. This is accomplished by modifying the model’s parameters to conform to a given entity’s features. The model may also produce fresh text in the same languages by applying the knowledge it has gained from the training data. This is accomplished by creating new text that is cohesive and grammatically sound utilizing the underlying patterns and structures that it has learned throughout the training process. Additionally, the model can be adjusted to fit particular use cases, such as giving translations or responding to queries. This can be accomplished by using a dataset created especially for that use case to train the model on.
ChatGPT performance was evaluated in different domains such as ophthalmology [64], medicine [65], programming [66], etc. In ophthalmology, two well-known multiple choice question banks from the high stakes Ophthalmic Knowledge Assessment Program (OKAP) exam to assess ChatGPT’s precision in the ophthalmology question-answering domain. The assessment sets ranged in difficulty from low to moderate and included recall, interpretation, and practical and clinical decision-making issues. In the two 260-question simulated tests, ChatGPT’s accuracy was 55.8% and 42.7%, respectively. The highest outcomes were in general medicine, whereas the worst outcomes were in neuro-ophthalmology, ophthalmic pathology, and intraocular malignancies. Its performance varied between subspecialties. These results are encouraging, but they also imply that ChatGPT may need to specialize through domain-specific pre-training in order to perform better in ophthalmology subspecialties. In medicine, ChatGPT was evaluated on the USMLE, which consists of three exams (Step 1, Step 2CK, and Step 3). Without any extra instruction or reinforcement, ChatGPT passed all three exams with a score at or around the passing mark. Furthermore, ChatGPT’s explanations displayed a high degree of concordance and insight. These findings imply that massive language models may be able to support clinical decision-making as well as medical education.
In programming [66], ChatGPT is quite good at fixing software flaws, but its main advantage over other approaches and AI models is its special capacity for communication with people, which enables it to increase the accuracy of an answer. ChatGPT was tested by researchers from Johannes Gutenberg University Mainz and University College London against “standard automated program repair techniques” and two deep-learning approaches to program repairs: CoCoNut from researchers at the University of Waterloo, Canada, and Codex, OpenAI’s GPT-3-based model that powers GitHub’s Copilot paired programming auto code-completion service. It is not new that ChatGPT may be used to address coding issues, but the researchers emphasize that its special ability to communicate with people provides it with a potential advantage over other methods and models. The researchers used the QuixBugs bug-fixing benchmark to evaluate ChatGPT’s performance. The researchers manually verified whether the suggested answer was accurate after running ChatGPT against 40 Python-only QuixBugs bugs. They asked the question four times because the accuracy of ChatGPT’s responses often vary. ChatGPT tied CoCoNut (19) and Codex (19) in resolving 19 of the 40 Python problems (21). However, only seven of the problems were resolved using conventional APR techniques. The researchers found that ChatGPT had a success rate of 77.5% with subsequent conversations.
In terms of natural languages, ChatGPT supports at least 95 languages including English, French, Greek, German, Hindi, Arabic, Mandarin, etc. It is important to remember that the performance of the model will differ based on the language and level of complexity of the text being created.
11. ChatGPT in Cybersecurity
ChatGPT poses several cybersecurity risks and concerns. One of the main concerns is the potential for the model to be misused for malicious purposes, such as generating fake news, spreading disinformation, or impersonating individuals. The ability of ChatGPT to generate human-like text makes it difficult to distinguish between real and fake content, increasing the risk of misinformation and deception. Additionally, the large size and sensitive nature of the data used to train ChatGPT raise privacy concerns. The model may have access to confidential information that could be misused if compromised. It is crucial to implement robust security measures to protect the model and the data it was trained on [67].
Another cybersecurity issue is the potential manipulation of ChatGPT’s outputs to spread misinformation or deceive individuals. Attackers could leverage the model to generate convincing phishing emails or impersonate individuals, leading to harmful consequences such as data breaches or unauthorized access to sensitive information. This highlights the importance of developing methods to detect and prevent such attacks. Businesses are particularly concerned about the use of ChatGPT in generating convincing phishing emails that can trick individuals into disclosing personal information or clicking on malicious links [68].
Furthermore, as the popularity of ChatGPT and similar AI tools grows, they attract the attention of cybercriminals and fraudsters who seek to exploit the technology for destructive purposes. It is difficult to determine whether specific malware was constructed using ChatGPT, but there are reports of cybercriminals using the tool to create scripts for dark web marketplaces. This raises concerns about the potential use of ChatGPT in facilitating cybercrime and illegal activities [69].
While ChatGPT can assist with security-related tasks and enhance productivity for security professionals, it is essential to address the cybersecurity risks associated with its use. Implementing strict security measures, ensuring responsible and ethical usage, and continuously monitoring and updating the model’s capabilities are crucial steps to mitigate these risks and protect against potential threats. Table 9 shows the main important cybersecurity risks associated with ChactGPT.
12. The Future of ChatGPT
ChatGPT has shown impressive results in its ability to generate human-like text and has been adopted by various industries for a range of applications. However, ChatGPT is not without limitations, such as its lack of contextual awareness and inability to fully understand the implications of the text it generates. Despite these limitations, the future of ChatGPT and its impact on the NLP landscape are bright. As technology continues to evolve, it is likely that ChatGPT will be able to overcome its limitations and become an even more integral part of the NLP landscape. Additionally, there is a growing trend towards the use of language models in fields such as customer service, content creation, and language translation, which will only continue to drive the importance and impact of ChatGPT in the future.
The scalability of ChatGPT is an additional advantage. ChatGPT can handle a high volume of talks without experiencing any lag because it is a cloud-based platform. This makes it perfect for companies and organizations that deal with a high amount of consumer enquiries because it can ensure that each one is dealt with promptly and effectively. Large language models (LLMs) and more specifically ChatGPT will be increasingly used in different domains where natural language processing is heavily present such as finance, medicine, education, and marketing, to name a few. ChatGPT and NLP in general will help in reshaping the future of these domains by incorporating conversational artificial intelligence.
12.1. Limitations of ChatGPT
Despite its promising results [64], ChatGPT’s impending adoption in ophthalmology might be constrained because it lacks the ability to interpret images. As ophthalmology is a specialty that mainly relies on visual examination and imaging to diagnose, treat, and monitor patients, this is a severe constraint. The Contrastive Language-Image Pretraining (CLIP) model, which can identify images and produce a text description that ChatGPT can then use to answer a question, maybe a necessary addition to LLMs like ChatGPT. This model can handle different forms of input. Although this method has promise, it is constrained by the fact that it relies heavily on internet-sourced image-text pairs (in the case of CLIP) that are not particular to our field. These data might not be sufficient to accurately separate minute and particular distinctions pertinent to ophthalmology and medicine.
A “superior” retinal detachment that needs a pneumatic retinopexy, as opposed to a “inferior” retinal detachment that could need a scleral buckle, may not be appropriately captioned with CLIP, for example. It will be crucial to work together to create safeguards for our patients as ChatGPT’s performance increases (perhaps through prompting tactics). These will entail guarding against biases for disadvantaged groups and assessing the risk or harm of taking on the advice given with LLMs like ChatGPT. This will be crucial for high-level decision-making problems that may be difficult to train for due to ambiguous online training data that reflect both the variation in research data and the patterns of practice around the world. Although we are enthusiastic about ChatGPT’s potential in ophthalmology, we are nevertheless wary about the technology’s potential clinical uses.
Despite being a robust AI-based chatbot system, ChatGPT has certain drawbacks. Only the information used to train it can be used to generate answers. ChatGPT lacks the capacity to perform an internet search because it is not a search engine. Instead, it generates responses using the knowledge it gained from training data. As a result, all output should be fact-checked for accuracy and timeliness. This leaves space for error [37].
The chatbot might not be able to offer detailed information or grasp conversational nuances or context. Business leaders should be mindful of the risks associated with potential bias as is the case with all AI products. The responses provided with ChatGPT will be biased if the data it was trained on are biased. In order to ensure that chatbot output is free of prejudice and objectionable content, all businesses must use extreme caution when reviewing it [41].
The fact that ChatGPT occasionally has a tendency to produce sentences that appear accurate or compelling but are actually false or nonsensical is one of its main critiques and limitations. It is frequent in language models and is known as “hallucination”. Additionally, it offers no references or citations regarding where to find the material. It is not optimal to use this chatbot by itself for electronic trailing and research.
The version that was released in November 2022 can only give details on things that happened in 2021 and before. As it continues to feed on data based on texts produced by humans, it will eventually reveal more recent happenings. Despite this flaw, users should be aware that it only has a limited grasp of facts because it relies on outdated datasets.
The fact that ChatGPT has come under examination is another drawback. Many academic institutions have prohibited its use. Because its outputs are based on human-generated texts, researchers and creatives have been concerned about copyright infringement. It also calls into question the propriety of substituting it for activities that demand human connection, including customer service support or even therapeutic counselling [4].
12.2. Research Trends
There are several ongoing research trends in the field of language generation. Adversarial training aims to develop models that can defend against malicious attacks, making them more robust and secure. Multi-modal generation is exploring the integration of visual and acoustic information with textual data to produce more descriptive and context-aware responses [70,71]. Personalization focuses on creating models that can adapt to individual users and generate personalized responses [72,73]. Explainability and interpretability aim to make language generation models more transparent and understandable to users [74]. Low-resource language generation aims to generate text in low-resource languages where data are limited [75]. Transfer learning is the use of pre-trained models to fine-tune them on specific tasks and domains [76]. Finally, integration with other AI technologies like reinforcement learning and generative adversarial networks is being explored to enhance the performance and capabilities of language generation models [77]. Table 10 provides some important research trends in language generations with challenges.
