SimpleStories Model Family

The SimpleStories models are a tiny model family created for interpretability research, trained on the SimpleStories dataset. This is the second iteration of the model family.

Paper: https://arxiv.org/abs/2504.09184
Training code: https://github.com/simple-stories/simple_stories_train
Traning checkpoints: https://wandb.ai/finke/simplestories-v2

Usage

python

import torch
from transformers import AutoTokenizer, LlamaForCausalLM


MODEL_SIZE = "1.25M"
model_path = "SimpleStories/SimpleStories-V2-{}".format(MODEL_SIZE)

tokenizer = AutoTokenizer.from_pretrained(model_path)
model = LlamaForCausalLM.from_pretrained(model_path)
model.to("cuda")
model.eval()

prompt = "The curious cat looked at the"

inputs = tokenizer(prompt, return_tensors="pt", add_special_tokens=False)
input_ids = inputs.input_ids.to("cuda")

eos_token_id = 1

with torch.no_grad():
    output_ids = model.generate(
        input_ids=input_ids,
        max_new_tokens=400,
        temperature=0.7,
        do_sample=True,
        eos_token_id=eos_token_id
)

output_text = tokenizer.decode(output_ids[0], skip_special_tokens=True)
print(f"\nGenerated text:\n{output_text}")

Dataset

The SimpleStories dataset is a collection of short stories generated by state-of-the-art language models. It features:

Story annotation with high-level concepts: theme, topic, style, etc.
Higher semantic and syntactic diversity through seeded story generation
Generated by 2024 models
Several NLP-metrics pre-computed to aid filtering
ASCII-only guarantee for the English dataset

Key improvements from previous version

Improved evaluation scores due to the increased training epochs
Pruning and optimization of the tokenizer resulting in vocabulary size from 4096 to 4019
Model training checkpoints are stored periodically in wandb for further research
