How to Build Custom GPTs on OpenAI

This document serves as a comprehensive guide for developing custom Generative Pre-trained Transformers (GPTs), tailored to specific needs and applications. It begins by simplifying the fundamental concepts of GPTs, by using easy to understand analogies to explain the architecture, principles of transformer models, and the mechanism of pre-training and fine-tuning. The guide then illustrates a step-by-step process of building a custom GPT.
