On November 27, 2025, news emerged that Singapore's National AI Programme (AISG) had recently unveiled the Southeast Asian multilingual large language model, Qwen-SEA-LION-v4. This model leverages Alibaba's open-source 'Tongyi Qianwen' (QianWen) model as its technical bedrock and has claimed the top spot on the 'Southeast Asian Language Model Comprehensive Evaluation Benchmark' (SEA-HELM) open-source model leaderboard (for models with fewer than 200 billion parameters).

Southeast Asia boasts a rich tapestry of languages, with daily communication frequently blending multiple tongues. Yet, the majority of mainstream global AI models are predominantly English-focused, posing challenges in adequately serving the local market. In this collaborative effort, Alibaba contributed the Qwen3-32B as the foundational model and offered post-training technical support. Meanwhile, AISG invested over 100 billion localized Southeast Asian language data points to further refine and optimize the model.

The Qwen-SEA-LION-v4 model is equipped with 32k token long-context capabilities and comes in 4-bit and 8-bit quantized versions. This enables it to operate seamlessly on consumer-grade laptops with 32GB of memory, thereby lowering the AI deployment threshold for local developers and small-to-medium-sized enterprises. Presently, the model is freely accessible for download worldwide via the AI Singapore official website and the Hugging Face open-source community.
