2. Introduction to GPT Language Models

  • 2-1. Overview of GPT models and progression from GPT-1 to GPT-4o

  • Generative Pre-trained Transformers (GPT) are a family of large language models (LLMs) developed by OpenAI. GPT models are designed to understand and generate text in natural language. Starting with GPT-1, released in 2018, each subsequent iteration has seen significant improvements. GPT-1, with 117 million parameters, was a rudimentary model capable of generating basic text. GPT-2, released in 2019, was a major advancement with 1.5 billion parameters, improving text output and generation speed. GPT-3, launched in 2020, dramatically increased the number of parameters to 175 billion, allowing for more sophisticated text generation capabilities. GPT-3.5, an enhanced version of GPT-3, was released in 2022 and became widely popular due to its human-like text generation and versatility. GPT-4, released in 2023, introduced multimodal capabilities, accepting both text and image inputs and providing more advanced reasoning and broader knowledge. The latest version, GPT-4o, released in 2024, further advanced multimodal abilities, including audio and video inputs, and featured a reduced latency period for more human-like interactions.

  • 2-2. OpenAI’s transition from non-profit to for-profit

  • OpenAI was established in 2015 as a non-profit organization with the mission of ensuring that artificial general intelligence (AGI) benefits all of humanity. Founders included notable tech leaders such as Elon Musk, Sam Altman, Peter Thiel, and more. Due to the high cost of research and development, OpenAI transitioned to a 'capped-profit' model in 2019. This model allows OpenAI to attract investments by limiting investors' returns to 100x their initial investment, balancing profit motives with its mission-driven goals. Partnerships with major tech companies, such as the $1 billion investment from Microsoft, have been instrumental in sustaining OpenAI's operations and allowing it to continue making significant advances in AI technology.

  • 2-3. Basic technical aspects of GPT models

  • GPT models are large-scale language prediction models, which are a type of neural network designed to process and generate human-like text. The architecture of these models is based on transformers, which use attention mechanisms to weigh the importance of different parts of input data, improving the model's ability to understand context and generate relevant responses. Pre-training involves using a large dataset to teach the model to predict the next word in a sequence, thereby developing an understanding of language patterns. Fine-tuning follows, where the model is adjusted for specific tasks, enhancing its performance. With each version, from GPT-1 to GPT-4o, the number of parameters—the adjustable elements of the model that influence its behavior—has dramatically increased, allowing for more complex and nuanced text generation. GPT-4o, the latest iteration, supports text, image, audio, and video inputs, making interactions even more seamless and human-like.

3. Comparison between GPT-3.5 and GPT-4
