I have a GPU now, so I can do ML experiments on @janitr_ai crypto/scam detection dataset

- I trained a tiny student BERT (transformer for the nonfamiliar), 3.6 MB ONNX model, still lightweight for a browser extension
- Still fully local on your device (no cloud inference)
- On frozen unseen holdout data (n=1,069), exact prediction accuracy improved from 77% -> 82%
- Scam detection improved: precision 91% -> 94%, recall 55% -> 61%
- Scam false alarm rate improved from 1.58% -> 1.21%

And models are on huggingface org now, handle is janitr
