# Twin Builder

60 quick "this or that" questions that distill you onto a trait vector — the first step in
distilling yourself onto a small model you own.

Play, then download your answers as SFT/DPO JSONL in the eval's exact prompt format,
fine-tune a small model, and evaluate it against the held-out sets in the
[CDT5058/digital-twin-evals](https://huggingface.co/datasets/CDT5058/digital-twin-evals) dataset.

Use **Test your twin** (feedback mode) on the end screen to keep grading the twin: every
correction becomes a free DPO pair for the next round of tuning.
