# Grounding demo

Interactive demo of Nutrient's grounding models: paste a document premise + a claim and see whether the
document **supports** it. Runs both models side by side:

- [`grounding-en`](https://huggingface.co/nutrientdocs/grounding-en) — open weights (Apache-2.0), English.
- [`grounding-multilingual`](https://huggingface.co/nutrientdocs/grounding-multilingual) — commercial,
  15+ languages.

## Secret required

The commercial model is loaded from a **private** repo, so this Space needs an `HF_TOKEN` **secret**
(Settings → Variables and secrets) with read access to it. The weights are used server-side only and are
never downloadable. Without the secret, the demo runs the open English model and marks the commercial one
_unavailable_.

Scores are temperature-calibrated support probabilities (per-model `T`).
