CultureConverse: A Multilingual Multi-turn Simulation Harness for Culturally Grounded Assistance in East and Southeast Asia

Current methods for evaluating large language models (LLMs) often oversimplify cultural understanding, focusing on single-turn factual recall rather than complex, multi-turn, culturally grounded assistance. A new simulation and evaluation harness, CultureConverse, has been introduced to address this gap, providing a scalable, multilingual platform for assessing LLMs in practical, culturally nuanced scenarios across ten East and Southeast Asian regions, 58 subgroup identities, and seven domains.

Why it matters

This development is crucial for organizations deploying or developing AI with global aspirations, as it highlights a significant gap in current AI evaluation methodologies concerning cultural competence. Ensuring LLMs can navigate and respect diverse cultural contexts is paramount for ethical AI deployment, market penetration, and maintaining trust with international user bases.

Key insights

• Existing cultural evaluations for LLMs primarily rely on single-turn factual recall, such as Multiple Choice Questions (MCQs), which do not accurately reflect real-world user interactions.
• A common user expectation for LLMs is practical assistance over multiple conversational turns within culturally specific contexts.
• CultureConverse is a new, scalable, multilingual simulation and evaluation harness designed for culturally grounded assistant dialogue.
• The harness covers 10 East and Southeast Asian regions, 58 subgroup identities, and 7 operational domains.
• Each simulated episode evaluates an assistant's ability to provide help and infer cultural constraints from incomplete information, resulting in a scored interaction.
• The associated CultureConverse-DS dataset comprises 14,610 benchmark (evaluation) episodes and 274,295 oracle-guided (gold-model) interactions.
