AutoResearch-tinystories-depth8

!AutoResearch Cover

AutoResearch-tinystories-depth8 is a 310.4M parameter decoder-only Transformer trained from scratch on TinyStories (karpathy/tinystories-gpt4-clean).

This model is part of the AutoResearch project, which focuses on training, evaluating, and releasing efficient language models with reproducible research workflows.

Overview

This is a 8-layer decoder-only Transformer trained on the TinyStories (karpathy/tinystories-gpt4-clean) dataset for 0.2 hours of wall-clock training time. The model achieves a validation bits-per-byte (val_bpb) of 0.522880 (perplexity: 1.4368) on the held-out validation set.

Usage

import torch
import pickle
import json
from train import GPT, GPTConfig, Tokenizer

# Load config
with open('config.json', 'r') as f:
    config_dict = json.load(f)
config = GPTConfig(**{k: v for k, v in config_dict.items() if k in GPTConfig.__dataclass_fields__})

# Load model
model = GPT(config)
state_dict = torch.load('model.pt', map_location='cpu')['state_dict']
model.load_state_dict(state_dict)
model.eval()

# Load tokenizer
with open('tokenizer.pkl', 'rb') as f:

# Generate
prompt = 'Once upon a time, '
input_ids = tokenizer.encode(prompt)

Limitations

  • Small model size limits language understanding and coherence
  • Trained on a single dataset (TinyStories) — limited domain
  • Fixed time budget training — not fully trained to convergence
  • No RLHF or safety alignment

Ethical Considerations

  • This is a research artifact, not a production model
  • The training data consists of synthetic stories (GPT-4 generated)
  • No harmful content filtering was applied
  • Intended for research and educational use only
