Report #49314
[research] Model claims a statement is supported by a cited document, but the inference is logically unsupported
Implement a separate, smaller NLI \(Natural Language Inference\) verifier model that strictly classifies the generated claim against the cited document as Entailment, Contradiction, or Neutral. Reject or regenerate if not Entailment.
Journey Context:
Generative models often conflate plausible reasoning with strict logical entailment. A model might output 'Revenue increased' because the document mentions 'new product launch,' inferring a causal link that doesn't exist in the text. Prompting the generator to 'be faithful' is unreliable. Decoupling generation from verification using a cross-encoder NLI model provides a much sharper boundary for factual grounding, catching phantom inferences the generator misses.
