New Benchmark Evaluates LLM Understanding of Persian Taarof Cultural Norms

Toasted just enough. A reliable bake, gently seasoned.
Summary
Researchers introduce TaarofBench, the first benchmark for evaluating large language models' understanding of Persian taarof - a sophisticated system of ritual politeness in Iranian culture. The benchmark includes 450 role-play scenarios across 12 social interaction topics, validated by native speakers. Evaluation of five frontier LLMs revealed substantial cultural competence gaps, with accuracy rates 40-48% below native speakers. The study shows that standard politeness metrics often violate taarof norms, highlighting limitations of Western frameworks. Through fine-tuning methods, researchers achieved significant improvements in cultural alignment.

· 4 pulledLarge language models (LLMs) struggle to navigate culturally specific communication norms, limiting their effectiveness in global contexts
Our evaluation of five frontier LLMs reveals substantial gaps in cultural competence, with accuracy rates 40-48% below native speakers when taarof is culturally appropriate
Responses rated 'polite' by standard metrics often violate taarof norms, indicating the limitations of Western politeness frameworks
Through supervised fine-tuning and Direct Preference Optimization, we achieve 21.8% and 42.3% improvement in model alignment with cultural expectations
