Idea-level AI-text detector: a LoRA adapter over
nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16. It answers whose ideas a document
contains, not who typed the sentences.
- Training corpus: 391k
- Reads at inference: a de-leaked (paraphrased) role-labelled outline of the document
Scored by comparing the next-token log-probabilities of the tokens human and ai, two-way
normalised, giving P(human). The detector fires when that falls below a calibrated threshold.
Thresholds are quantiles over held-out human documents and are not included here: a cut
from one model or input form is meaningless against another's scores.
Fuller documentation and evaluation results to follow.
