OpenArch
Python implementations of modern open-source LLM architectures — written from scratch, one model at a time.
This repository contains hand-written PyTorch implementations of the model architectures cataloged in Sebastian Raschka's
LLM Architecture Gallery
. Each model is implemented to the best of my knowledge from the original papers, technical reports, reference
config.json
files, and the excellent writeups by Sebastian Raschka and Machine Learning Mastery.
The goal is not to compete with
transformers
or other production libraries. The goal is
clarity and learning
: a single readable file per architecture, with the structural choices (attention type, normalization, layer mix, MoE routing, positional encoding) made explicit and easy to compare side-by-side.
