2-1. Overview
ChatGPT is a chatbot and virtual assistant developed by OpenAI and launched on November 30, 2022. Based on large language models (LLMs), it allows users to refine and steer a conversation towards a desired length, format, style, level of detail, and language. Successive user prompts and replies are considered at each conversation stage as context. ChatGPT has contributed significantly to the AI boom, driving rapid investment and gaining substantial public attention. By January 2023, it had over 100 million users, and helped raise OpenAI's valuation to $86 billion.
2-2. Development History
ChatGPT was launched on November 30, 2022, by OpenAI. Initially released as a freely available research preview, it is now operated on a freemium model due to its popularity. Users on the free tier can access GPT-4o and GPT-3.5, while paid subscriptions such as 'Plus', 'Team', and 'Enterprise' offer additional features like DALL-E 3 image generation and increased GPT-4o usage limit. OpenAI has progressively upgraded the model's capabilities, leveraging supervised learning and reinforcement learning from human feedback (RLHF) to improve performance.
2-3. Key Features
ChatGPT's versatility extends beyond mere conversation. It can write and debug computer programs, compose music, teleplays, fairy tales, and student essays; answer test questions; generate business ideas; write poetry and song lyrics; translate and summarize text; emulate a Linux system; simulate entire chat rooms; and play games like tic-tac-toe. Though effective, it sometimes generates plausible but incorrect answers, a phenomenon known as 'hallucination'. Safety measures, including a 'Moderation endpoint' API, are in place to filter offensive content. Plugin support added in March 2023 enables web browsing and code interpretation among other functionalities.
2-4. Versions (GPT-3.5, GPT-4, GPT-4o)
ChatGPT is built on the GPT series developed by OpenAI, specifically GPT-3.5, GPT-4, and GPT-4o for conversational applications. GPT-3.5 possesses knowledge up to January 2022, GPT-4's knowledge cut-off is December 2023, and GPT-4o's knowledge cut-off is October 2023. Paid subscriptions allow real-time web searches. GPT-4 Turbo, released in November 2023, has a much larger context window. GPT-4o, launched in May 2024, is capable of analyzing and generating text, images, and sound, and is twice as fast and costs half as much as GPT-4 Turbo. GPT-4o is available to all users within a usage limit, with a higher limit for Plus subscribers.
3. Technological Architecture
3-1. Generative Pre-trained Transformer Models
ChatGPT is built on OpenAI’s proprietary series of generative pre-trained transformer (GPT) models. These models, specifically GPT-3.5, GPT-4, and GPT-4o, were fine-tuned to target conversational usage. ChatGPT uses large language models (LLMs) which enable users to refine and steer a conversation towards a desired length, format, style, level of detail, and language. This architecture allows ChatGPT to handle successive user prompts and replies, considering them as context.
3-2. Training Data and Process
The training data for ChatGPT includes software manual pages, information about internet phenomena such as bulletin board systems, various programming languages, and the text of Wikipedia. To build the safety system against harmful content (e.g., sexual abuse, violence, racism, sexism), OpenAI used outsourced Kenyan workers to label harmful content, which was then used to train a model to detect such content. ChatGPT initially employed Microsoft Azure's supercomputing infrastructure, powered by Nvidia GPUs and specifically built for OpenAI, costing 'hundreds of millions of dollars'. By 2023, Microsoft had dramatically upgraded this infrastructure in response to ChatGPT's success.
3-3. Supervised Learning and Reinforcement Learning from Human Feedback
ChatGPT's fine-tuning process leveraged two primary approaches: supervised learning and reinforcement learning from human feedback (RLHF). In supervised learning, human trainers played both the user and the AI assistant roles to help improve the model’s performance. In the RLHF stage, human trainers first ranked responses generated by the model during previous conversations. These rankings were used to create 'reward models' that fine-tuned the model further through several iterations of proximal policy optimization. Additionally, to combat prompt 'jailbreaking' techniques that bypass content restrictions, OpenAI implemented adversarial training methods that pit multiple chatbots against each other.
4. Applications of ChatGPT
