question-answering model by undefined. 6,07,777 downloads.

Unique: Explicitly trained on SQuAD v2's unanswerable questions subset, learning to recognize when no valid answer exists rather than always extracting a span — unlike SQuAD v1-only models that lack this capability and will hallucinate answers for out-of-scope questions

vs others: More reliable than v1-trained models in production because it can admit when it doesn't know, reducing false positive answers and improving user trust in systems that route unanswerable questions to humans
