For every week since February 8, 2026, Chinese-origin AI models have accounted for at least 30% of the enterprise token volume on OpenRouter. By mid-2026, that share reached a weekly peak of 46%, according to a CNBC investigation published July 7. That figure stood at 11% averaged over the prior twelve months — and just 4.5% in the first half of 2025.
Open-source Chinese models are consistently 60% to 90% cheaper than the leading offerings from Anthropic and OpenAI. DeepSeek V4 Flash costs $0.14 per million input tokens, while OpenAI’s GPT-5.5 is priced at $5.00. For high-volume enterprise users, these differentials — ranging from 4x to 100x cheaper — are difficult to ignore.
The U.S. government restricts access to frontier models like GPT-5.6 Sol to a select group of approximately 20 vetted organizations. Yet enterprises are effectively routing around these constraints. The structural contradiction is clear: as the U.S. tightens access to its most advanced domestic models, the market is gravitating toward Chinese alternatives that are not only available but significantly more affordable.
DeepSeek recently became the number one trending software vendor on the Ramp index. The provider breakdown tells the story: DeepSeek holds 17.6% of OpenRouter’s routed tokens. Alibaba’s Qwen follows at 13.9%. Chinese-origin models now account for 46.4% of routed tokens, compared to 35.7% for US-origin models.
This reliance introduces a new layer of operational risk. The June 12 suspension of Anthropic’s Fable 5 and Mythos 5 models under U.S. export-control directives established a precedent for government-mandated model shutdowns. Enterprises choosing Chinese models are balancing immediate cost benefits against potential regulatory or geopolitical volatility.
By creating a tiered economy where the most capable models are locked behind federal clearance, the government has inadvertently incentivized a shift toward external, lower-cost alternatives.
