# addGPT: Teaching Transformers to Add

A transformer encoder-decoder that learns integer addition, demonstrating algorithmic learning capabilities.

## Model Description

- **Architecture**: Transformer encoder-decoder
- **Parameters**: ~2.7M (tiny config)
- **Task**: Integer addition (up to 5-digit numbers)
- **Accuracy**: >99% on held-out test set

## Usage

```python
# Download checkpoint
from huggingface_hub import hf_hub_download
checkpoint_path = hf_hub_download(repo_id="m-bano/addGPT", filename="ckpt_step12500.pt")

# Or use the provided script
# python download_checkpoint.py
```

See the [GitHub repository](https://github.com/mbano/addGPT) for complete code and usage instructions.

## Training Details
