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.

China is pursuing a low-cost, open-source AI model, similar to Android's market strategy. This contrasts with the US's expensive, high-performance "iPhone" approach. This accessibility and cost-effectiveness could allow Chinese AI to dominate the global market, especially in developing nations.

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.

A nation's advantage is its "intelligent capital stock": its total GPU compute power multiplied by the quality of its AI models. This explains the US restricting GPU sales to China, which counters by excelling in open-source models to close the gap.

Securing a lead in computing power over rivals is not a victory in itself; it is a temporary advantage. If that time isn't used to master national security adoption and win global markets, the lead becomes worthless. Victory is not guaranteed by simply having more data centers.

A technological lead in AI research is temporary and meaningless if the technology isn't widely adopted and integrated throughout the economy and government. A competitor with slightly inferior tech but superior population-wide adoption and proficiency could ultimately gain the real-world advantage.

While the US focuses on creating the most advanced AI models, China's real strength may be its proven ability to orchestrate society-wide technology adoption. Deep integration and widespread public enthusiasm for AI could ultimately provide a more durable competitive advantage.

While the U.S. leads in closed, proprietary AI models like OpenAI's, Chinese companies now dominate the leaderboards for open-source models. Because they are cheaper and easier to deploy, these Chinese models are seeing rapid global uptake, challenging the U.S.'s perceived lead in AI through wider diffusion and application.
