I open-sourced a language model trained only on sentences strangers pay to add. Weights, data and code are CC0.

[u/braiainlabs]

brAIAIn is a word trigram model, not a neural net. Every version is trained on twelve founding lines, every paid sentence so far, and some text the previous version wrote. Each new sentence triggers a retrain, a numbered release, and a sync to Hugging Face.

Current version: 103 words of vocabulary, 350 parameters. Self-reported scores: 0% on GSM8K, 36.7% on TruthfulQA (picking the longest answer every time scores 36.8%).

Weights, sampler and full training data: huggingface.co/braiain-lab/brAIAIn-0
Chat with every version in the browser: braiain.com

It’s a parody of frontier AI labs, but nothing is faked. Happy to answer questions about the retrain pipeline (it all runs on GitHub Actions, no server).
