rasbt/LLMs-from-scratch
An educational project providing step-by-step code to build a ChatGPT-like Large Language Model (LLM) from scratch using PyTorch.
Core Features
Step-by-step implementation of a GPT-like LLM.
Covers development, pretraining, and finetuning processes.
Explains LLM internals with clear text, diagrams, and examples.
Includes code for loading and finetuning larger pretrained models.
Official code repository for the 'Build a Large Language Model (From Scratch)' book.
Quick Start
git clone --depth 1 https://github.com/rasbt/LLMs-from-scratch.gitDetailed Introduction
This project serves as the official code repository for the book 'Build a Large Language Model (From Scratch)', offering a unique opportunity to understand LLMs from the inside out. It guides users through coding their own functional LLM in PyTorch, mirroring the techniques used in foundational models like ChatGPT. By breaking down complex concepts into manageable steps, it empowers learners to grasp the core mechanics of deep learning and natural language processing, making advanced AI accessible for practical implementation and deeper comprehension.
