Troubleshooting

Issue: Benchmark results not reproducible
Solution: Set random seeds, document model version, use fixed datasets

Issue: Evaluation too slow
Solution: Use subset sampling, parallelize, cache embeddings

Issue: Inconsistent scores across runs
Solution: Increase sample size, use statistical significance tests

Issue: Missing domain-specific coverage
Solution: Create custom benchmarks, extend existing with domain cases

Integration Points

Standardize AI security evaluation with comprehensive benchmarks.
