Predicts answer spans by computing logit scores for each token's probability of being the answer start and end position. The model outputs raw logits that are converted to probabilities via softmax, with the final answer confidence computed as the product of start and end token probabilities, enabling ranking of multiple candidate answers.
Unique: Outputs token-level logits for both start and end positions, enabling fine-grained analysis and custom span ranking logic vs black-box APIs that return only top-1 answer
vs alternatives: Provides interpretability and flexibility for downstream ranking/filtering vs fixed single-answer output, at the cost of requiring more complex post-processing
Designed to integrate with retrieval pipelines where a dense retriever (e.g., DPR, ColBERT) returns top-k candidate passages, and this model re-ranks and extracts answers from those passages. The model's multilingual capabilities enable end-to-end retrieval-augmented QA across 100+ languages without separate retrieval models per language.
Unique: Multilingual design enables single QA model to work with any language's retriever output, whereas monolingual models require language-specific retrieval + QA pipelines
vs alternatives: Simplifies architecture by eliminating language-specific QA models in retrieval pipelines; reduces latency vs separate ranking and extraction stages
Model weights are available for fine-tuning on domain-specific QA datasets using standard PyTorch/HuggingFace training loops. The model's XLM-RoBERTa backbone can be unfrozen to adapt to specialized vocabularies and answer patterns, with transfer learning from SQuAD v2 pretraining providing strong initialization.
Unique: Model weights are released in SafeTensors format for safe deserialization and easy fine-tuning integration with HuggingFace ecosystem, vs older pickle-based formats
vs alternatives: Transfer learning from SQuAD v2 + multilingual pretraining provides stronger initialization than training from scratch, reducing data requirements and training time vs domain-specific models
