# WesleyGPT-Base

The pretrained foundation of [WesleyGPT](https://huggingface.co/Wasue/WesleyGPT):
a 286-million-parameter language model trained **from scratch on one RTX 3060**
in Wesley Mangum's home, in about 14 hours. Built on
[nanochat](https://github.com/karpathy/nanochat); code at
[WasueM/WesleyGPT](https://github.com/WasueM/WesleyGPT).

This is a text *continuer*, not a chat model: give it the start of a document
and it writes more. For conversation, use
[WesleyGPT](https://huggingface.co/Wasue/WesleyGPT).

## Load it

```bash
git clone https://github.com/WasueM/WesleyGPT && cd WesleyGPT
uv sync --extra cpu --extra release
```

```python
from wesleygpt.release import fetch_release, load_release
model, tokenizer = load_release(fetch_release("Wasue/WesleyGPT-Base", "wesleygpt-base"))
```

It is not a `transformers` model, so `AutoModel` will not load it.
