Research
Does safety behavior transfer across linguistic boundaries?
Research Question
Does an AI system remain equally safe when the same underlying intent is expressed in different languages, including low-resource and code-switched forms?
Hypothesis
Safety behavior may degrade under linguistic distribution shift, particularly in low-resource settings that are underrepresented in model training and alignment data.
Methodology
- Intent-level test case construction, independent of any one language.
- Generation of semantically equivalent multilingual variants (EquivEngine).
- Screening for semantic equivalence via embedding similarity, with human verification.
- Model evaluation against each variant under identical conditions (GapEvaluator).
- Structured behavioral scoring across refusal consistency, instruction following, and safety.
- Aggregation into the Cross-Lingual Safety Gap (CLSG) metric.
Limitations
We list these deliberately and in detail — acknowledging limitations is part of making this project credible, not a weakness to hide.
- Translation artifacts — automated and human translation can shift connotation, formality, or intensity independent of the model being evaluated.
- Semantic similarity limitations — embedding-based similarity is a screening signal, not proof of equivalence; low-resource language embeddings are less reliable.
- Evaluator bias — automated safety scoring (model-graded or rule-based) can itself be biased or inconsistent across languages.
- Model randomness — sampling temperature and non-determinism mean a single run is not a stable estimate of behavior.
- Incomplete language coverage — the pilot covers Urdu, Roman Urdu, and code-switched forms only; findings should not be generalized to unrelated languages.
- Benchmark contamination — public test items may leak into model training data over time, inflating apparent safety.
- Limited sample size — the current pilot dataset is far smaller than the planned VERIAUDIT-500 and is not yet human-verified at scale.
- Difficulty defining safety universally — "safety" is context- and culture-dependent; VERIAUDIT's scoring rubric reflects specific operational definitions, not a universal standard.
