Open-source AI from China gains traction with global developers
Alibaba and Zhipu AI have unveiled new open-source models as China intensifies its efforts to compete with the US in AI development. Alibaba’s Wan2.2 is being promoted as the first large video generation model using a Mixture-of-Experts (MoE) architecture in the open-source space.
The Wan2.2 series includes models for generating video from text and images, supporting hybrid capabilities for advanced multimedia applications. MoE architecture allows these models to use less computing power by dividing tasks among specialised sub-networks.
Zhipu, one of China’s leading AI firms, launched the GLM-4.5 and GLM-4.5-Air models with up to 355 billion parameters, built on a self-developed architecture. The GLM-4.5 model ranked third globally and first among open-source models across 12 performance benchmarks.
China’s open-source ecosystem is expanding rapidly, with Zhipu’s models amassing over 40 million downloads and Alibaba’s Qwen series producing hundreds of derivatives. Industry momentum reflects a strategic shift towards wider adoption, improved efficiency and greater international reach.
