LKValues: First benchmark and instruction corpus for Sri Lankan societal value alignment in LLMs

Researchers introduce LKValues, a resource suite for aligning LLMs with Sri Lankan cultural values, derived from a trilingual survey of 205 respondents. The suite includes LKvaluesIT, a 150k-instance Sinhala-English instruction corpus, and LKvaluesBench, a 1,000-instance evaluation benchmark. Fine-tuning experiments on Qwen and Aya-Expanse models show that current LLMs exhibit cultural and low-resource alignment gaps, and that LKValues fine-tuning reduces invalid outputs and cross-lingual disparities. The work offers a replicable pipeline for country-specific pluralist value alignment in underrepresented languages.
