2. Introduction to ChatGPT

• 2-1. Overview of ChatGPT by OpenAI

• ChatGPT is a chatbot and virtual assistant developed by OpenAI and launched on November 30, 2022. It is based on large language models (LLMs) which allow users to refine and steer a conversation towards a desired length, format, style, level of detail, and language. ChatGPT has been credited with starting the AI boom, leading to significant public attention and investment in artificial intelligence. As of January 2023, it had become the fastest-growing consumer software application in history, with over 100 million users. ChatGPT operates on OpenAI's proprietary series of generative pre-trained transformer (GPT) models, with the latest iterations including GPT-4o. It is fine-tuned for conversational applications using supervised learning and reinforcement learning from human feedback (RLHF).

• 2-2. Development timeline and milestones

• ChatGPT was launched on November 30, 2022, quickly gaining over one million users by December 4, 2022. By January 2023, it had over 100 million users. In February 2023, OpenAI introduced the premium service ChatGPT Plus. April 2023 saw the integration of third-party plugins and a browsing mode for premium users. In May 2023, an iOS app was launched, followed by an Android app in July 2023. The company continued to release updates and new models, including GPT-4 in March 2023, GPT-4 Turbo in November 2023, and GPT-4o in May 2024. Each iteration brought more advanced features and improved performance.

• 2-3. Initial reception and rapid growth

• Upon its release, ChatGPT was immediately popular, reaching over one million users within days. By January 2023, it was the fastest-growing consumer application, with more than 100 million users. This popularity spurred other tech companies to develop their own AI models, such as Microsoft's Copilot and Google's Bard. ChatGPT’s rapid growth was attributed to its versatile capabilities, such as writing and debugging code, composing text, and supporting numerous languages. Despite concerns about the potential for displacing human intelligence and enabling plagiarism, ChatGPT maintained significant user engagement and widespread industry adoption.

3. Technical Specifications and Advancements

• 3-1. Generative Pre-trained Transformer Models (GPT-3.5, GPT-4, GPT-4o)

• ChatGPT is built on OpenAI’s proprietary series of generative pre-trained transformer (GPT) models, specifically GPT-3.5, GPT-4, and GPT-4o. The fine-tuning process of these models leveraged supervised learning and reinforcement learning from human feedback (RLHF). ChatGPT was released as a freely available research preview and rapidly became the fastest-growing consumer software application in history, with over 100 million users by January 2023, contributing to OpenAI’s valuation of $86 billion. GPT-4o, the latest model released in May 2024, is particularly noted for its enhanced capabilities, supporting a wide range of inputs and outputs including text, audio, image, and video, and responding to audio inputs with an average response time similar to human conversation. Unlike earlier versions, GPT-4o is geared towards providing faster and more natural human-computer interactions.

• 3-2. Human Feedback and Reinforcement Learning

• The training of ChatGPT models involved both supervised learning and reinforcement learning from human feedback (RLHF). Human trainers played both roles in supervised learning: that of the user and the AI assistant. During the reinforcement learning stage, human trainers ranked the responses generated by the model in previous conversations to create 'reward models', which were then used to fine-tune the model through iterations of proximal policy optimization. This fine-tuning improved the model's performance and minimized harmful or deceitful responses as much as possible. Additionally, outsourced Kenyan workers were employed to label harmful content, which helped to build a system to detect such content in the future.

• 3-3. Introduction of Multimodality in GPT-4o

• GPT-4o introduced multimodality capabilities, allowing it to accept inputs and generate outputs in various formats, including text, audio, image, and video. This advancement marked a significant improvement over previous versions, enabling more natural and effective human-computer interactions. With GPT-4o, users can talk to the model in real-time, upload images, and receive translations or historical context for shared pictures. It is also noted for its improved vision and audio understanding, enhanced language capabilities across over 50 languages, and faster response times, making it highly suitable for a wide range of applications.

• 3-4. Voice and Image Capabilities

• ChatGPT has advanced voice and image capabilities, particularly with the latest version, GPT-4o. The model can respond to and generate audio and image outputs, making interactions more dynamic and versatile. Users can engage in real-time voice conversations and share images for translation or further discussion. The desktop version of ChatGPT, launched for both free and paid users, integrates these capabilities seamlessly into various user tasks, like taking and discussing screenshots. The model also supports voice input via an iOS app and can generate and edit images using DALL-E 3 for subscribers to the Plus and Enterprise tiers.

4. ChatGPT Applications

5. Controversies and Ethical Concerns

• 5-1. Privacy Issues and Data Usage Policies

• OpenAI collects data from ChatGPT users to train and fine-tune the service further. Users can upvote or downvote responses they receive from ChatGPT and fill in a text field with additional feedback. This feedback helps OpenAI improve the model's performance. However, this data collection has raised concerns about user privacy, particularly when sensitive information may be inadvertently shared and stored.

• 5-2. Concerns about Biased and Erroneous Outputs

• ChatGPT is known to 'hallucinate,' which means it sometimes generates plausible-sounding but incorrect or nonsensical answers. This behavior is common for large language models. Bias in training data can also lead ChatGPT to generate content that may be offensive or harmful, such as negative misrepresentations of certain groups. For instance, ChatGPT has produced rap lyrics that suggested women and scientists of color were inferior to white male scientists.

• 5-3. Legal Issues and Copyright Infringements

• ChatGPT's reliance on vast amounts of internet data for training has led to multiple legal concerns. In June 2023, two writers sued OpenAI, alleging the use of their copyrighted material without permission. Other legal actions have come from high-profile authors like Sarah Silverman, who accused OpenAI of violating copyright laws by using their works for training purposes without authorization. These issues highlight the ongoing challenges in balancing AI development with intellectual property rights.

• 5-4. Employment Impact and Societal Implications

• The rapid adoption of ChatGPT across various industries has sparked debates about its impact on employment. There is concern that ChatGPT could displace jobs that involve repetitive tasks or specific rule-based work.
