# Developers need to understand how Large Language models work

## Summary

A developer advocates for understanding how Large Language Models work internally, and promotes their book 'The Inner Workings of Large Language Models' as an accessible resource explaining LLM concepts for both developers and non-developers.

## Content

I believe it is crucial for developers who use AI to understand how it works. This knowledge can help them become better and more effective users of AI tools.

Some months ago, I wrote a book called _The Inner Workings of Large Language Models_. It explains in detail how LLMs actually work, using language that is easy to understand.

It took many months of research and writing to find a way to explain these concepts clearly, but the feedback I have received suggests that the book does this very well.

The book is written in a way that can also be read and understood by people who are not developers.
