Chapter 2: Understanding How ChatGPT Works
2.1 Introduction ChatGPT may seem magical, but its abilities are grounded in sophisticated mathematics, computer science, and linguistic principles. Understanding what makes ChatGPT tick demystifies the black box and empowers users to interact with it more effectively. This chapter unpacks the architecture, training process, and mechanisms behind the model's intelligence. 2.2 The Foundation: Generative Pre-trained Transformer (GPT) At the core of ChatGPT lies the GPT (Generative Pre-trained Transformer) architecture. Developed by OpenAI, GPT is a type of language model designed to generate coherent, contextually relevant text. Key Features: Generative : It doesn't just recognize or classify language—it creates it. Pre-trained : The model is trained on massive text datasets before any fine-tuning. Transformer-based : Uses attention mechanisms to understand relationships between words. 2.3 The Transformer Architecture ...
