The global AI race today is often framed as a rivalry between United States and China—but instead of one clear winner, each side is dominating a different part of the field.
At a simple level, experts describe it as a contest between “brains” and “bodies.” The US leads in AI “brains”—the software side—while China has the edge in AI “bodies,” meaning robotics and real-world deployment.
On the “brains” side, American companies have taken an early lead with powerful large language models (LLMs). The launch of ChatGPT by OpenAI in 2022 marked a turning point, bringing AI into mainstream use. Other US firms like Google and Anthropic quickly followed, investing billions into similar systems. These models are widely used for writing, coding, research, and business tasks, and they rely heavily on advanced microchips—many of which are designed by Nvidia.
Crucially, the US has used export controls to limit China’s access to these high-end chips and the specialised machines needed to produce them, helping it maintain an advantage in AI development.
But China has been catching up. The release of DeepSeek showed that Chinese developers can build competitive AI systems at a much lower cost. While some experts say US models are still slightly more advanced, Chinese alternatives are often far cheaper and increasingly capable. China also benefits from a more open-source approach, allowing developers to build on each other’s work quickly rather than starting from scratch.
Where China clearly leads is in AI “bodies”—robotics and large-scale deployment. Backed by heavy government investment, the country has built a massive robotics ecosystem, with millions of robots already in use across factories and services. It dominates areas like drone technology, automated manufacturing, and even humanoid robots. In some cases, fully automated “dark factories” can run with little or no human involvement.
This strength comes from China’s manufacturing base, which makes it easier to design, build, and scale physical technologies. The government is also pushing robotics as a solution to long-term challenges like an ageing population and labour shortages.
However, even China’s robots still rely on advanced AI “brains” to perform complex tasks—and that’s where the US retains an edge. High-level decision-making AI, sometimes called agentic AI, is still largely led by American research and companies.
What makes the race unpredictable is that both countries are now trying to close their weaknesses. The US is investing more in robotics, while China is rapidly improving its software and AI models.
In the end, there may not be a single moment of victory. Instead, the outcome will likely depend on who can apply AI most effectively across their economy—whether in business, healthcare, defence, or everyday life. The real winner may not be the one who invents the best technology first, but the one who scales it fastest and embeds it most deeply into society.
