Yep, it’s true. If you have some technical skill, you can download this repo from github: rasbt/LLMs-from-scratch: Implementing a ChatGPT-like LLM in PyTorch from scratch, step by step and build your own LLM.

What I like about this is that it demystifies LLMs. LLMs aren’t magic, they aren’t Skynet and they’re not some sentient being. They’re software. That’s all.

So ignore all the hype and handwaving about LLMs and go make your own.

Prefer to read it in dead tree form? You can get the book here.
