Day 1: How I Built My Own Large Language Model (LLM) AI from Scratch


Building a Large Language Model (LLM) from scratch has been my dream. I want to understand how OpenAI, Meta, and Mistral AI build their GPT models. It seems amazing to create my own model.
However, when I started searching for documentation or videos on this subject, I found either no results or unsatisfactory ones. Some developers have published projects on GitHub about this topic, but I couldnât understand much from them.
I quickly realized that building my own LLM or GPT couldnât be done by a single developer like me with just a personal computer. It requires a deep understanding of mathematics, data science, machine learning, and deep learning before even starting to code and train an LLM.
So, what can I do to achieve this goal? đ€
One night, after 10 PM, just before sleeping, I started searching again on Google, ChatGPT, and YouTube for books or anything that could help me start creating, building, and understanding how to build my own LLM.
After some research using terms like âLLM from scratchâ and searching for people working at Google, OpenAI, Meta, and Mistral, I found an awesome person who has written a book about âHow to Build an LLM from Scratch.â

You can find this book at this link:Â Build a Large Language Model from Scratch.
In this blog series, I want to share my adventure of creating my own LLM. I will guide you through the steps required to create your own LLM, covering the essential aspects of data preprocessing, model architecture, training, and more.
