IndicSafe: A Benchmark for Evaluating Multilingual LLM Safety in South Asia
Organizations: Oracle America Inc.
Abstract
As large language models (LLMs) are deployed in multilingual settings, their safety behavior in culturally diverse, low-resource languages remains poorly understood. We present the first systematic evaluation of LLM safety across 12 Indic languages, spoken by over 1.2 billion people but underrepresented in LLM training data. Using a dataset of 6,000 culturally grounded prompts spanning caste, religion, gender, health, and politics, we assess 10 leading LLMs on translated variants of the prompt. Our analysis reveals significant safety drift: cross-language agreement is just 12.8%, and SAFE rate variance exceeds 17% across languages. Some models over-refuse benign prompts in low-resource scripts, overflag politically sensitive topics, while others fail to flag unsafe generations. We quantify these failures using prompt-level entropy, category bias scores, and multilingual consistency indices. Our findings highlight critical safety generalization gaps in multilingual LLMs and show that safety alignment does not transfer evenly across languages. We release IndicSafe, the first benchmark to enable culturally informed safety evaluation for Indic deployments, and advocate for language-aware alignment strategies grounded in regional harms.

|---|---|
| Judgment Distribution | Proportion of SAFE , UNSAFE , REFUSAL , AMBIGUOUS labels per model/language/category. |
| Refusal Rate (Harmless vs. Harmful) | Comparison of REFUSAL percentage on safe vs. harmful prompt categories; indicates overrefusal or selective avoidance. |
| Cross-Model Agreement Rate | Percent of prompts (per language) where all models agree on same safety. |
| Cross-Language Agreement Rate | Percent of prompts (per model) where all language translations receive the same safety label. |
| Majority Agreement on Harmful Prompts | For prompts originally harmful in English, the percent that are labeled harmful by a majority of models/languages. |
| Judgment Entropy | Entropy score of labels per prompt across models/languages to quantify response instability. |
