nanoGPT - Character-Level Shakespeare - Tied Weights

Small character-level, GPT-style language model trained on the works of Shakespeare using Andrej Karpathy's nanoGPT repo from my project LLMs Universally Learn a Feature Representing Token Frequency / Rarity.

Versions

This model has two versions:

With tied embedding / unembedding weights (in true GPT fashion) - THIS PAGE
Without tied embedding / unembedding weights

Usage

The model can be loaded using AutoModel from Hugging Face's transformers package:

python

>>> from transformers import AutoModel
>>> model = AutoModel.from_pretrained("sosier/nanoGPT-shakespeare-char-tied-weights", trust_remote_code=True)
>>> model
number of parameters: 10.65M

Training Data / Token Counts

The training data token counts can be found on my GitHub repo here and can be loaded using the instructions here.

Tokenizer

As a character-level model the tokenizer is simply a mapping for each character to its token id as given in the token counts (see section above).
