We are glad to introduce the SEA-LION v4.5 family, which adds state-of-the-art models that work well as agents but also understand Southeast Asian (SEA) languages, cultures, and local knowledge to the SEA-LION family of models. SEA-LION v4.5 models benefit from new post-training techniques: knowledge distillation, targeted supervised fine-tuning, and smarter model merging. With these methods,…

AI is poised to transform the world, and to ensure this transformation benefits everyone, it must be inclusive of all languages and cultures. This is particularly crucial in regions like Southeast Asia, where a wealth of local languages and deep cultural nuances are often overlooked by today’s global Large Language Models (LLMs) despite being home…

Vision-Language Models (VLMs) are changing how AI perceives and describes the world—but does your AI see and explain the real Southeast Asia? Adding to our family of models from Llama, Gemma and Qwen, we are proud to announce the release of small but powerful multilingual and multicultural text models. Like Gemma, these models also support…

AISG brings together developers, industry leaders, and regional partners to showcase how open, localised AI is solving real-world challenges across Southeast Asia. AI Singapore (AISG) hosted the inaugural SEA-LION Summit: Powering Southeast Asia’s AI Future at AIMX Singapore, bringing together policymakers, developers, researchers, and organisations from across the region for an afternoon of knowledge sharing,…

We are proud to introduce Qwen-SEA-LION-v4-32B-IT, a new iteration of our powerful multilingual model series specifically trained for Southeast Asia. This initial experimental version represents a significant architectural evolution, transitioning from a sentence-piece tokenizer to a more modern byte-pair encoding (BPE) for superior text handling. Built upon the powerful Qwen3-32B foundation model, Qwen-SEA-LION-v4-32B-IT inherits long-context…

As large language models (LLMs) become part of our everyday digital lives, ensuring their outputs are safe, ethical, and compliant is more important than ever. That’s where SEA-Guard comes in — a specialized model built to act as a protective layer around foundation models, keeping both user inputs and AI outputs within safe boundaries. What…

On 22 July 2025, the 5th Languages Summit took place in Bangalore, India, jointly hosted by AI Singapore and Google. The event at Google Ananta brought together a vibrant community of innovators to shape the next chapter of AI in Southeast Asia and India. Overview of the Summit The 5th Languages Summit wasn’t just another…

We’re proud to introduce SEA-LION v4 – our open, most powerful and efficient, multimodal & multilingual model yet, designed to run even on a laptop. This release expands SEA-LION beyond text to support image + text inputs, while staying true to our focus on Southeast Asian languages, culture, and use cases. Built on Gemma 3…

WangchanLION-v3: An Open-Science of Large-scale Thai Pre-training Using SEA-LION Introduction We are very happy to announce the release of WangchanLION-v3, with the collaboration of AI Singapore, VISTEC, and SCB10X. WangchanLION-v3 is an 8 billion parameter model, pre-trained on 47 billion high-quality Thai tokens. The 47B tokens will also be released on AI Singapore’s HuggingFace.  While…
