WesleyGPT-Base
The pretrained foundation of 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; code at 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.
Load it
git clone https://github.com/WasueM/WesleyGPT && cd WesleyGPT
uv sync --extra cpu --extra release
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.
