Does the document actually support this claim?

Paste a document premise (a table or passage) and a claim. The grounding model scores whether the document supports the claim. Scores are temperature-calibrated support probabilities; the verdict is the model's decision at 0.5.

Pick an example below (its expected answer is shown) or type your own. The non-English examples are cases the English model gets wrong — switch to the multilingual model.
