    A PyTorch implementation of the Transformer model in "Attention is All You Need".

    Project mention: Question: LLMs | /r/learnmachinelearning | 2023-07-06

    I did implement an "LLM" proof of concept from scratch in a course for my masters, pretty much doing a small implementation of a transformer from the Attention is all you Need paper (plus other resources). It was useless, but was a great experience to understand how it works. There are a few implementation like this out there, like this one: (first google result). I think it is a fun exercise (the amount of fun depends on how much of a masochist you are :) ).
