Architectural Choices in China's Open-Source AI Ecosystem: Building Beyond DeepSeek

Summary

Chinese open-source artificial intelligence development has shifted focus toward architectural choices, ecosystem toolchains, and domestic hardware integration following the January 2025 DeepSeek release. Leading groups have adopted Mixture-of-Experts architectures like Kimi K2 and Qwen3 to balance capability, dynamic compute allocation, and operating costs. Development expanded beyond text into multimodal domains including speech, video, and 3D systems while prioritizing smaller 0.5B to 30B distilled models under permissive Apache 2.0 licensing. Furthermore, model releases increasingly provide day-zero alignment with domestic inference and training infrastructure, including Huawei Ascend, Cambricon, and Baidu Kunlun chips. Production serving engines such as Moonshot AI's Mooncake and Baidu's FastDeploy 2.0 reflect a transition from standalone models to comprehensive system-level design.

Takeaways

1. 1

   Mixture-of-Experts architectures became the default design for leading models like Kimi K2, MiniMax M2, and Qwen3 to dynamically allocate compute and control deployment costs.

2. 2

   Smaller models in the 0.5B to 30B range gained widespread usage for local execution, fine-tuning, and agent workflows through distillation from 100B to 700B teacher models.

3. 3

   Domestic hardware adoption expanded from inference to training, with models like Baidu Qianfan-VL, Zhipu GLM-Image, and TeleChat3 trained entirely on Chinese accelerator clusters.
