US Lawmakers Probe Chinese AI Models in Companies
U.S. lawmakers are jointly investigating the rising use of Chinese-developed AI models by American companies amid growing geopolitical tensions. House panels have sent letters to firms such as Cursor and Airbnb as part of a probe into risks linked to China-origin models. Chinese models have gained traction because they are closing performance gaps with U.S. rivals and can be cheaper to run. The investigation highlights concerns about embedded censorship, intellectual property and security, and lawmakers and experts are discussing options ranging from procurement restrictions to risk disclosures — though legal and practical obstacles remain.
A congressional investigation into adoption of China-origin AI models could prompt procurement restrictions, regulatory guidance, or disclosure requirements that materially affect how U.S. companies select and deploy foundational AI models.

Key Takeaways & Evidence Grounding
- The House Committee on Homeland Security and the House Select Committee on China announced a joint investigation into the growing adoption of Chinese-developed AI models.
- Committee chairmen sent letters to Cursor and Airbnb about their 'use of or exposure to these risks' from AI developed in China.
- Cursor built its Composer 2 model using the Chinese AI model Kimi, developed by Moonshot AI; Cursor is slated to be acquired by Elon Musk’s SpaceX for $60 billion.
- Some U.S. government departments have banned the usage of certain Chinese AI models (including DeepSeek), but corporate adoption by U.S. companies is not federally prohibited.
- Experts and lawmakers are considering policy options such as federal procurement restrictions and disseminating findings about risks and vulnerabilities associated with China-origin AI models.

Lawmakers Seek DoorDash Data on Chinese AI Models
U.S. lawmakers have requested information from DoorDash about its evaluation and deployment of Chinese-developed AI models amid growing concern over national security and dependence on PRC-developed systems. The request comes from the chairmen of two House committees conducting a joint investigation into security implications of U.S. companies using Chinese AI models. CNBC reports DoorDash publicly acknowledged deploying Chinese models for some workloads and its AI research lab said Moonshot AI’s Kimi K2.6 and Anthropic’s Fable 5 outperformed other models it used. The probe has already included letters to other companies such as Cursor and Airbnb as lawmakers consider risk-based safeguards and a U.S. strategy for open-weight models.
China Considers AI Model Export Controls; US Benchmarks
Chinese and U.S. policymakers are independently weighing controls on access to advanced AI models, with each side calibrating its proposals in light of the other's capabilities. Reuters reports Chinese Ministry of Commerce meetings with National Development and Reform Commission officials and companies including Alibaba, ByteDance and Z.ai to discuss potentially restricting overseas access to China's most capable models and criminalizing leaks under national security law. Separately, The Washington Post says the U.S. (Trump administration and industry groups) has considered a capability framework that would benchmark U.S. models against leading Chinese open-source models, streamlining market access for models below that threshold. Rapid overseas adoption of Chinese models—measured by token volumes on developer routing platforms and fast uptake of Z.ai’s GLM-5.2—appears to be a key driver of policy concern on both sides.
Chinese AI Models Surge Globally, Washington Worried
Chinese AI models, including those from DeepSeek, Z.ai, and Alibaba, have seen a significant surge in global adoption during 2026, particularly on developer platforms OpenRouter and Vercel. On OpenRouter, Chinese models accounted for 57-67% of tokens used in the week of Sept. 14, up from 6-13% in February. On Vercel, their share reached 55% in August, up from 11% in January. This growth is driven by lower costs and improved performance, especially in coding and agentic tasks, though U.S. frontier models still attract more overall spending. The trend has drawn concern in Washington, with two House committees investigating the impact. Officials worry about security risks and Beijing's influence, especially as Chinese companies may access Nvidia chips remotely and use distillation techniques. Businesses in the 'Global South' are the heaviest users of Chinese models, with 67% of tokens used by these companies on OpenRouter.
