China's promotion of open-weight models is a strategic maneuver to exert global influence. By controlling the underlying models that answer questions about history, borders, and values, a nation can shape global narratives and project soft power, much like Hollywood did for the U.S.

By limiting access to top-tier proprietary models, U.S. policy may have ironically forced China to develop more efficient, open-source alternatives. This strategy is more effective for global adoption, as other countries can freely adapt these models without API limits or vendor lock-in.

Joe Tsai reframes the US-China 'AI race' as a marathon won by adoption speed, not model size. He notes China’s focus on open source and smaller, specialized models (e.g., for mobile devices) is designed for faster proliferation and practical application. The goal is to diffuse technology throughout the economy quickly, rather than simply building the single most powerful model.

The emergence of high-quality open-source models from China drastically shortens the innovation window of closed-source leaders. This competition is healthy for startups, providing them with a broader array of cheaper, powerful models to build on and preventing a single company from becoming a chokepoint.

Counterintuitively, China leads in open-source AI models as a deliberate strategy. This approach allows them to attract global developer talent to accelerate their progress. It also serves to commoditize software, which complements their national strength in hardware manufacturing, a classic competitive tactic.

The rise of Chinese AI models like DeepSeek and Kimmy in 2025 was driven by the startup and developer communities, not large enterprises. This bottom-up adoption pattern is reshaping the open-source landscape, creating a new competitive dynamic where nimble startups are leveraging these models long before they are vetted by corporate buyers.

Unable to compete globally on inference-as-a-service due to US chip sanctions, China has pivoted to releasing top-tier open-source models. This serves as a powerful soft power play, appealing to other nations and building a technological sphere of influence independent of the US.

The initial fear around DeepSeq was about China surpassing US AI capabilities. The lasting, more subtle impact is that it broke a psychological barrier, making it commonplace for American developers and companies to adopt and build upon powerful open-source models originating from China.

Z.AI and other Chinese labs recognize Western enterprises won't use their APIs due to trust and data concerns. By open-sourcing models, they bypass this barrier to gain developer adoption, global mindshare, and brand credibility, viewing it as a pragmatic go-to-market tactic rather than an ideological stance.
