Chinese AI models from DeepSeek, Z.ai and Alibaba now account for a majority of token usage on OpenRouter and Vercel, two major developer gateways. Their combined share reached 57%-67% on OpenRouter in mid-September and 55% on Vercel in August, up from single digits earlier in 2026. The surge comes as two U.S. House committees investigate the national security implications of rising adoption.

Key Facts

Chinese models accounted for 57%-67% of tokens used on OpenRouter in the week of Sept. 14, up from 6%-13% in February.
On Vercel, Chinese models' share rose to 55% in August from 11% in January.
Two U.S. House committees are investigating the impact of rising adoption of Chinese AI models.
OpenRouter's data covers companies in the U.S., Europe and 82 countries across Central and South America, Africa, and Asia.
OpenAI and Anthropic announced new, cheaper models earlier this week.

Platform Adoption Data

Chinese AI models have moved from a small share of usage to a majority on two major developer platforms that provide gateways for companies to access models from different providers. On OpenRouter, they accounted for 57%-67% of tokens used in the week of Sept. 14, up from 6%-13% in February. On Vercel, their share rose to 55% in August from 11% in January. OpenRouter's data related to companies in the U.S., Europe and what it defines as the 'Global South' — 82 countries across Central and South America, Africa, and Asia. Vercel did not specify its data's geographical breakdown.

Washington's Response

Concern is growing in Washington, where two U.S. House Committees are investigating the impact of rising adoption of Chinese models. The U.S. has sought to preserve its AI lead by restricting Chinese AI companies from buying the most advanced chips through export controls. Washington is concerned about them accessing Nvidia chips remotely, via overseas data centers, and gaining ground by using 'distillation' where new models mimic older, more established ones. Chinese AI represents 'real economic and security risks for the United States,' said Daniel Remler, a senior fellow in the technology and national security program at the Center for a New American Security (CNAS). 'The ultimate concern is that the integration of Chinese AI models pulls countries into a Chinese technology sphere of influence that hardens into geopolitical alignment,' he told CNBC.

Cost and Performance Drivers

Chinese open source models released this year 'can credibly perform in advanced agentic use cases, especially in regards to coding, in a way that was just not true in late 2025,' Peter Walker, head of insights at OpenRouter, told CNBC. They are also 'incredibly cost-effective compared to most models from American labs,' he added. Price is key in rising adoption of Chinese models, Harpreet Arora, head of agentic infrastructure at Vercel, told CNBC. 'Chinese models are becoming capable enough for more tasks at a much lower cost. Once a model meets the quality bar for the job, that price difference becomes compelling,' Arora said. But he added that companies still want to use frontier U.S. models for some more complicated tasks.
