Ecosystem overview for everything related to from-scratch.
"LLMs-from-scratch" is the official code repository for Sebastian Raschka's book *Build a Large Language Model (From Scratch)*. It guides users through developing, pretraining, and finetuning a GPT-like LLM from the ground up, mirroring the approach of large-scale foundational models. The project implements all code in PyTorch, avoiding external LLM libraries, and includes functionalities for loading larger pretrained models for finetuning. It's designed for educational purposes, focusing on in-depth understanding of LLM mechanics.
