| Challenge: | Existing LLM benchmarks are capable of evaluating specific capabilities in English as well as in various mid- to low-resource languages, but a comprehensive and culturally representative evaluation suite for the SEA languages has not been developed thus far. |
| Approach: | They propose a holistic linguistic and cultural LLM evaluation suite that emphasizes SEA languages and introduces a leaderboard that allows users to understand models’ multilingual and multicultural performance. |
| Outcome: | The proposed evaluation suite emphasizes SEA languages and supports Filipino, Indonesian, Tamil, Thai, and Vietnamese. |

| Challenge: | Southeast Asia (SEA) is home to over 1,300 indigenous languages and 671 million people . prevailing AI models suffer from a significant lack of representation of texts, images, and audio datasets from SEA . |
| Approach: | They propose to provide a resource center that provides standardized corpora in nearly 1,000 SEA languages across three modalities. |
| Outcome: | a new benchmark assesses the quality of AI models on 36 SEA languages across 13 tasks . the results highlight the importance of SEA as a culturally diverse region . |

| Challenge: | Reliable multilingual evaluation is difficult and culturally appropriate evaluation is even harder to achieve. |
| Approach: | They propose a multilingual evaluation framework that aims to mitigate these biases by improving translations and annotation practices. |
| Outcome: | The proposed framework improves translation quality and cultural coverage and is culturally sensitive and culturally agnostic. |
