Published by Easyspub Publishing House Do it! [Introduction to AI Agent Development Using LLM] book For about a month, I was able to steadily build my LLM skills by reading the book daily with challenge participants and conducting code execution tests. Additionally, through the author's direct lecture, I was able to hear about the writing purpose and journey of this book and feel its value, and through the lively Q&A session, I was able to achieve more than 100% of my goals. I would like to express my deep gratitude to Inflearn and Easyspub Publishing House for organizing this event.
