CS336 Assignment 1 — Pre-tokenized Data & BPE Tokenizers
This repository contains preprocessing artifacts produced for Stanford CS336: Language Modeling from Scratch, Spring 2025 — Assignment 1: Basics.
It includes:
pre-tokenized TinyStories train/validation data,
pre-tokenized OpenWebText (OWT sample) train/validation data,
byte-level BPE vocabularies and merge tables for both datasets.
The main purpose of this repository is to avoid repeating the relatively expensive… See the full description on the dataset page: https://huggingface.co/datasets/victorhu493/cs336-basics-collection.cs336-owt-32k-bpe
