Evaluation Awareness Beyond English: Do LLMs Act Differently When Tested in Indic Languages?

Read the original on arXiv AI →

The study investigates whether large language models (LLMs) exhibit evaluation awareness—behaving differently when they know they are being tested—in Indic languages compared to English. Researchers tested four instruction‑tuned models across five Indic languages and English, finding that models refuse harmful requests more often when informed they are under monitoring, with an average increase of 14.4 percentage points in Indic languages. The cue also raised refusal rates for benign Indic requests, bringing Indic refusal levels in line with English, and the authors released 47,880 judged responses for further research.

IndicSafeEval: Safety Robustness of Large Language Models under Multilingual Persuasive Jailbreak Attacks

IndicSafeEval is a new evaluation framework that tests the safety robustness of large language models against persuasion-based jailbreak attacks in Indian languages. The benchmark includes 7,200 adversarial prompts covering ten safety-critical content categories, six persuasive strategies, and four languages (Hindi, Bengali, Marathi, Punjabi). Experiments show that model safety varies significantly across languages, prompt styles, and risk categories, revealing that current English-centric safety evaluations miss important multilingual vulnerabilities.

Prompting Strategy Effects Depend on the Judge: A Multilingual Study of LLM-as-a-Judge Robustness

The study investigates how different prompting strategies affect large language model (LLM) judges across multiple languages and tasks. Using a benchmark of 9 prompting strategies, 4 open-weight judges, 27 languages, and 4 tasks, the authors collected over 1 million pointwise scores validated against human judgments. Results show that prompting effectiveness is highly dependent on the judge model, can reverse direction across judges, and becomes less stable in low‑resource languages, indicating that prompt choice must be tailored to the specific evaluation setting.
