# SealQA: Raising the Bar for Reasoning in Search-Augmented Language Models

## Core Concept

SealQA is a benchmark designed to evaluate language models that augment their reasoning with web search capabilities. The benchmark specifically targets scenarios where web search yields conflicting, noisy, or misleading information, exposing the gap between models' advertised reasoning capabilities and their actual performance under realistic conditions.

The benchmark reveals that even frontier reasoning models struggle significantly (17.1% to 6.3% accuracy on challenging variants), demonstrating that naive search integration fails when faced with information clutter, contradictions, and irrelevant results—common in real-world information retrieval.

## Architecture Overview

- **Three Evaluation Variants**: Seal-0 (baseline), Seal-Hard (aggressive noise), and LongSeal (extended context)
- **Conflict Detection**: Questions designed where search results contradict each other or the ground truth
- **Long-Context Reasoning**: Extended documents requiring deep multi-document understanding
- **Needle-in-Haystack Scenarios**: Evaluate models' ability to identify relevant information amid distraction
- **Retrieval Robustness**: Test resilience to noisy search results, ranked incorrectly, or tangentially related
- **Reproducibility Focus**: Public benchmark on Hugging Face for comparative evaluation

## Implementation

The following steps outline how to construct and evaluate search-augmented reasoning systems:

1. **Define fact-seeking questions** - Create question sets where web search alone is insufficient
2. **Generate diverse search results** - Collect results with varying relevance, conflicts, and noise profiles
3. **Implement search integration** - Add retrieval modules to the base language model
4. **Evaluate reasoning quality** - Measure accuracy on questions requiring multi-document synthesis
5. **Measure robustness** - Test performance degradation as search result quality decreases
6. **Analyze failure modes** - Identify where models are misled by conflicting information

        self.model_name = model_name
        self.search = search_engine

    def search_and_filter(self, query: str, top_k: int = 5) -> List[Dict[str, Any]]:
        """Retrieve and filter search results."""
        results = self.search.query(query, top_k=top_k * 3)
        # Implement filtering logic
        filtered = self._deduplicate_and_rank(results)[:top_k]
        return filtered

        if not results:
            return 0.0
        agreement_scores = [r.get('agreement_score', 0.5) for r in results]
        return sum(agreement_scores) / len(agreement_scores)

            if self._match_answer(predicted, ground_truth):

## Practical Guidance

**Evaluation dimensions:**
- **Seal-0**: Clean search results with minimal noise; tests basic multi-document reasoning
- **Seal-Hard**: Conflicting information, ranked incorrectly, or deliberately misleading results
- **LongSeal**: Extended contexts (10K+ tokens) requiring deep information synthesis

**When to use:**
- Evaluating search-augmented LLM systems before deployment
- Benchmarking information retrieval pipeline improvements
- Testing reasoning robustness to noisy or contradictory data
- Assessing multi-document understanding and conflict resolution

**When NOT to use:**
- Single-document QA tasks (use other benchmarks like SQuAD)
- Closed-domain retrieval where search is guaranteed clean
- Tasks not requiring web search or external knowledge
- Real-time applications where benchmark evaluation adds overhead

**Common failure modes observed:**
- **Surface-level matching**: Models pick up keyword matches without deep understanding
- **Recency bias**: Models over-weight recent or highly-ranked results without verification
- **Contradiction blindness**: Failing to notice conflicting information in search results
- **Incomplete reasoning**: Providing answers without synthesizing all relevant evidence
- **Confidence calibration**: Expressing high confidence despite conflicting evidence

## Reference

The benchmark includes three variants with publicly available datasets on Hugging Face. Performance gaps (frontier models achieving only 6.3-17.1% accuracy on hardest variants) highlight significant room for improvement in reasoning robustness under realistic information retrieval conditions.
