Chinese models cross 30% of U.S. OpenRouter traffic as House committees widen probe
OpenRouter data shows Chinese open-weight models holding above 30% of weekly U.S. token traffic since February, peaking at 46%, as House committees escalate their investigation and Beijing weighs its own export curbs.
Chinese open-weight models have accounted for more than 30% of the tokens U.S. companies consume on OpenRouter every week since Feb. 8, peaking at 46%, according to platform data reported by CNBC. Against a trailing 12-month average of 11% and a 4.5% share in the first half of 2025, the shift isn’t a wobble in a chart. It’s a procurement pattern.
The mechanism is unglamorous: price. Justin Summerville, who works on data and analytics at OpenRouter, says the Chinese open-source models run “60% to 90% cheaper” than leading OpenAI and Anthropic offerings. At agent-workflow scale, that arithmetic collapses fast. Chris Clark, OpenRouter’s COO, says Chinese models are “disproportionately represented in agent workflows run by U.S. companies,” the workloads where token counts pile up and margins get decided.
Individual defections illustrate the pull. Lindy CEO Flo Crivello says the startup moved 100% of its traffic from Claude to DeepSeek, a switch he expects to save millions. Z.ai’s GLM-5.2, released in June, now sits in the top five on LaunchLemonade, an agent platform for regulated industries. Vercel’s head of agentic infrastructure Harpreet Arora describes the ramp bluntly: “In its first full week after launch, daily token volume grew about 27x and the number of customers using it grew about 80x.”
Washington noticed. The House Committee on Homeland Security and the House Select Committee on China announced a joint investigation of U.S. corporate adoption in April and have since sent letters to Cursor and Airbnb, with an aide framing the question as “whether the United States has a sufficient open-weight AI strategy.” A State Department spokesperson was less procedural, arguing the models “are designed to advance Beijing’s narratives, censor dissent, and reflect CCP ideology and values.”
Beijing, per Reuters, has spent the past month meeting with Alibaba, ByteDance and Z.ai about restricting overseas access to their most advanced systems. A May roundtable summarized in a Supreme People’s Court journal floated a tiered regime that would keep the most sensitive frontier models domestic.
The Decoder notes OpenRouter is one venue and the 30–46% figure blends developer and production traffic. Even discounted, both capitals are now treating the same open-weight pipeline as a strategic asset worth constraining. The 2019 Huawei-era export logic has found its software analogue, and this time the flow runs the other direction.
