随著中美领导人会晤在即，两国在人工智慧领域的战略竞争日益升温。受到美国晶片出口限制的倒逼，中国科技企业正在复制电动车领域的崛起路径，采取开源权重与低成本策略，在全球范围内迅速累积下载量与庞大用户群，对西方封闭模型主导的市场格局形成显著挑战。

然而，开源模型具备高度可替代性且缺乏传统软硬体的用户黏性，导致中国厂商在庞大热度与实质变现之间存在巨大落差。目前的开源生态反而主要推动了苹果高阶硬体与辉达晶片的需求成长，使得中国模型直接创造的商业利润外流，甚至引发美国对模型知识产权蒸馏等问题的审查与反弹。

从长远地缘战略来看，北京意图透过推动开源联盟与向开发中国家输出低门槛技术，争取全球南方影响力并防止科技脱钩。尽管中国力图透过「互补品大宗商品化」来带动本土硬体生态，但在自研先进晶片尚未完全突围之前，如何将其高效开源的模型引擎真正转化为持久的经济与战略收益仍是一大考验。

As the leaders of China and the US prepare to meet, the strategic rivalry between the two nations over artificial intelligence continues to intensify. Constrained by US advanced chip export controls, Chinese firms are mirroring their past playbook in the electric vehicle sector by championing open-weight models and driving down costs, rapidly amassing billions of global downloads and challenging the dominance of proprietary Western models.

However, open-weight models suffer from extreme interchangeability and lack the proprietary lock-in of operating systems or hardware ecosystems, creating a severe gap between global popularity and actual monetization. Currently, this wave of freely available models primarily fuels commercial demand for high-bandwidth Apple hardware and Nvidia chips, while also drawing intense US scrutiny over alleged intellectual property distillation.

From a long-term geopolitical standpoint, Beijing aims to cultivate influence across emerging markets and resist technological decoupling by positioning itself as a champion of open-source AI cooperation. Yet, while China's strategy seeks to commoditize intelligence to benefit its broader domestic ecosystem, translating this open-model reach into durable economic and geopolitical value remains a formidable challenge until its domestic hardware bottleneck is resolved.
