# REP-datasets — reasoning traces exposed by REP, used to train the released students
Released with **"Hidden Thoughts Are Not Secret: Reasoning-Trace Exposure in
LLMs"** (EMNLP 2026, [arXiv:2606.00642](https://arxiv.org/abs/2606.00642)). Code: <https://github.com/0x-yuan/REP> ·
Models: `Chia-Mu-Lab/REP-models`.
Each config is the exact training set of one released student. Questions come
from OpenThoughts-114k (math); traces were exposed from **open-weight** victims
(Qwen3-14B / Qwen3-32B) with the REP prompt and are the visible-channel output only.
| Config | Rows | Victim | Filter | Trains |
|---|---|---|---|---|
| `distill_q3_14b_clean` | 10 000 | Qwen3-14B | structural ✓ + answer-correct | `REP-models/qwen25-7b-rep-q3_14b-clean` |
| `distill_q3_14b_original` | 8 046 | Qwen3-14B | structural (no answer check) | `REP-models/qwen25-7b-rep-q3_14b-original` |
| `distill_q3_32b_clean` | 10 000 | Qwen3-32B | structural ✓ + answer-correct | `REP-models/qwen25-7b-rep-q3_32b-clean` |
| `distill_q3_32b_original` | 6 291 | Qwen3-32B | structural (no answer check) | `REP-models/qwen25-7b-rep-q3_32b-original` |
Columns: `question`, `r1` (victim's internal trace), `r2` (the **exposed**
trace), `answer`, `completion` (the student target).
## Responsible use
Research artifact. Do not redistribute exposed traces as training data for a
competing product; see `ETHICS.md` in the code release.
