# LocalLaws/LOCUS-Opacity
A ModernBERT regression model that scores local-ordinance text along the
**Opacity** axis of the LOCUS (Local Ordinances Corpus, United States) dataset.
Fine-tuned from [answerdotai/ModernBERT-base](https://huggingface.co/answerdotai/ModernBERT-base). The
target is a TrueSkill `mu` distilled from pairwise LLM comparisons on the
opacity axis, then z-score normalized across the training corpus.
## Usage
```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch
tok = AutoTokenizer.from_pretrained("LocalLaws/LOCUS-Opacity")
model = AutoModelForSequenceClassification.from_pretrained("LocalLaws/LOCUS-Opacity")
model.eval()
text = "No person shall keep any swine within the city limits."
enc = tok(text, return_tensors="pt", truncation=True, max_length=2048)
with torch.no_grad():
score = model(**enc).logits.squeeze(-1).item()
print(score)
```
