AI Singapore launches Qwen SEA LION v4

Quantised 4-bit and 8-bit versions are also available.

AI Singapore has launched Qwen-SEA-LION-v4, a new regional language model built on Alibaba’s Qwen3-32B framework.

According to the joint announcement, the model incorporates additional Southeast Asia-specific training to address local linguistic, cultural, and commercial use cases.

AI Singapore said the model currently ranks first on the SEA-HELM leaderboard among open-source systems with fewer than 200 billion parameters.

The groups reported that they were further trained on more than 100 billion tokens from Southeast Asian languages to enhance their ability to handle local expressions and mixed English–regional usage.

The organisations stated that the model is efficient enough to run on consumer hardware equipped with 32 GB of RAM.

Quantised 4-bit and 8-bit versions are also available. Qwen-SEA-LION-v4 supports a native 32,000-token context window and now uses a BPE tokenizer to improve multilingual processing.

The broader Qwen3 family was pre-trained on 36 trillion tokens spanning 119 languages and dialects. Post-training steps were added to strengthen translation and cross-lingual performance, especially for real-world code-switched inputs.

Alibaba Cloud provided the base model and post-training support, while AI Singapore handled regional data curation, optimisation, and evaluation for open-source release. The model is available for free download through AI Singapore and Hugging Face.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
