SeaLLMs-v3

SeaLLMs-v3 is the third generation of the SeaLLMs project from DAMO Academy and SUTD, building open foundation and chat models tailored for Southeast Asian languages including Indonesian, Vietnamese, Thai, Tagalog, Malay, Burmese, Khmer, Lao, Tamil, and Javanese alongside English and Chinese. It ships in four variants: 7B-Chat, 7B base, 1.5B-Chat, and 1.5B base.

The release emphasized trustworthiness alongside performance, with safety tuning addressing both general and culture-specific considerations and mechanisms to reduce hallucinations. The work was published at NAACL 2025. Weights are released under the SeaLLMs terms of use rather than a standard open-source license, so commercial deployers should read those terms carefully.
