Southeast Asian (SEA) languages get little systematic evaluation. BHASA addresses this gap with an evaluation suite in three parts: 2. **[SEA-LION: Southeast Asian Languages in One Network](https://md.research.elamur.ai/free/en/papers/ng-2025-sea-lion-southeast-asian-languages/)** *(2025 · 29 citations)* Most open LLMs are designed around English and perform poorly on Southeast Asian languages.
