Digital Event Horizon
A new wave of innovation is sweeping through China's open-source AI ecosystem, driven by distinct leadership strategies and architectural choices that prioritize sustainability, flexibility, and scalability. With Mixture-of-Experts (MoE) becoming the default choice for leading models, the community is pushing forward a full set of engineering assets and exploring new directions in multimodal and agent-based AI. This shift marks a profound change in how AI systems are built and deployed, with far-reaching implications for the global compute landscape.
China's open-source AI ecosystem has shifted towards architectural choices prioritizing sustainability, flexibility, and scalability. The Mixture-of-Experts (MoE) architecture has become the default choice for leading AI researchers and developers in China. MoE's ability to dynamically allocate compute resources makes it an attractive solution for China's real-world constraints. The ecosystem is also seeing traction in multimodal and agent-based directions, with reusable system-level capabilities emerging. A preference for small models (0.5B-30B range) has become evident, with large models used as "teacher models" for distillation. More permissive open-source licenses, such as Apache 2.0, have contributed to the ecosystem's growth and reduced deployment friction.
China's open-source AI ecosystem has experienced significant advancements since January 2025, marked by a profound shift towards architectural choices that prioritize sustainability, flexibility, and scalability. The rapid growth of this ecosystem is attributed to the emergence of distinct leadership strategies among Chinese companies, which are driving innovation and competition in various domains.
At the forefront of this revolution are models based on the Mixture-of-Experts (MoE) architecture, which has become the default choice for leading AI researchers and developers contributing to the open-source community. MoE's ability to allocate compute resources dynamically across tasks and deployment environments has made it an attractive solution for China's real-world constraints. By controlling cost and ensuring models can be trained, deployed, and widely adopted, MoE has emerged as a natural solution for achieving the best cost-performance balance.
The dominance of MoE is not limited to text-based models; multimodal and agent-based directions have also gained significant traction, with the community pushing forward a full set of engineering assets, including inference deployment, datasets, evaluation, toolchains, workflows, and edge-to-cloud coordination. This parallel emergence of video generation tools, 3D components, distillation datasets, and agent frameworks points to something larger than isolated breakthroughs – it indicates reusable system-level capabilities.
Furthermore, the preference for small models in the 0.5B-30B range has become increasingly evident, with leading players using large MoE models as capability ceilings or "teacher models" that are then distilled down into many smaller practical models. This creates a clear structure: a few very large models at the top and many practical models underneath.
The shift towards more permissive open-source licenses has also contributed to the ecosystem's growth, with Apache 2.0 becoming close to the default choice for open models from the Chinese community. More permissive licenses have lowered the friction around using, modifying, and deploying models in production, making it easier for companies to move open models into real systems.
The "DeepSeek Moment" of January 2025 did more than trigger a wave of new open models; it forced a deeper reconsideration of how AI systems should be built when open source is no longer optional but foundational and why those underlying choices now carry strategic weight. Chinese companies are no longer optimizing isolated models; instead, they are pursuing distinct architectural paths aimed at building full ecosystems suited to an open-source world.
This new era of open-source AI ecosystems is marked by a profound shift towards sustainability, flexibility, and scalability. As the ecosystem continues to evolve, it will be essential to monitor how China responds to U.S. hardware sales and export controls, as well as the impact of these factors on the global compute landscape.
