Although I majored in mechanical engineering, I have worked continuously reading and writing code since graduating. I am a Google AI/Cloud GDE. I run the TensorFlow blog (tensorflow.blog) and explore the fascinating boundary between software and science by writing and translating books about machine learning and deep learning.
I have written 『Deep Learning You Study by Building It Yourself』 (Hanbit Media, 2025), 『Self-Study Machine Learning + Deep Learning (Revised Edition)』 (Hanbit Media, 2025), 『Self-Study Data Analysis with Python』 (Hanbit Media, 2023), 『The Art of Conversing with ChatGPT』 (Hanbit Media, 2023), and 『Do it!

Book Introduction
Less complex theory, more essential core concepts!
The most concise guide to mastering language modeling
As a follow-up to Andriy Burkov's bestseller "The Hundred-Page Machine Learning Book," this book starts with the basics of language modeling and covers the latest Large Language Models (LLMs) concisely yet thoroughly. Through this book, readers can systematically learn everything from the mathematical foundations of modern machine learning and neural networks to count-based and RNN-based language models implemented in Python, building Transformers from scratch with PyTorch, and hands-on LLM practice (instruction fine-tuning, prompt engineering).
Based on executable Python code and a Google Colab environment, this practice-oriented book allows anyone to expand their understanding by following along step-by-step. It explains the journey of language models—from simple n-gram statistics to the core AI technology of today—starting with count-based methods up to the latest Transformer architectures, covering both principles and implementation. Each chapter builds progressively on previous content, and even complex concepts are structured to be easily understood through clear explanations, illustrations, and hands-on exercises.
Testimonials
“This book clears up the conceptual confusion about how machine learning actually works. It is a gem of a book that captures machine learning with clarity.” - Vint Cerf (Internet pioneer and Turing Award winner)
“This is an excellent starting point for those taking their first steps into language modeling and aiming for the cutting edge.” - Tomáš Mikolov (Developer of word2vec and FastText)
“Andrej paints a journey from the foundations of linear algebra to the implementation of Transformers with over 100 masterful brushstrokes.” - Florian Douetteau (Co-founder and CEO of Dataiku)
“One of the most comprehensive yet concise guides to deeply understanding the inner workings of LLMs.” - Jerry Liu (Co-founder and CEO of LlamaIndex)
“Andrej has an almost supernatural talent for breaking down massive AI concepts into bite-sized pieces, making the reader feel like ‘I finally get it!’” - Jorge Torres (CEO of MindsDB)
I read "LLM from Scratch" before this book, so I was able to understand the parts that summarized the key points. I think it would be good to watch this along with other courses.
This is a course for completing the reading challenge certification, and book-related courses are provided for free. Thank you for translating such a great book!
