China’s AI Models Are Quietly Going Global as Firms Seek Control

Summary

The article argues that Chinese open-weight AI models are spreading internationally as companies seek greater control over model access, costs, data and product strategy. It opens with Anthropic’s reported 18-day global shutdown of its two strongest models after a U.S. Commerce Department export-control directive, presenting the episode as a “regulatory kill-switch” that exposed the operational risk of dependence on a foreign provider. The article says companies also face a commercial switch: API suppliers can change prices, terms or product priorities, and may eventually compete directly with their customers. Against that backdrop, it describes Cursor, Harvey and Thomson Reuters as moving toward Chinese model bases. Cursor’s Composer 2 was identified by developers as using Moonshot’s Kimi K2.5; Cursor later acknowledged that omitting attribution was a mistake and said the use was authorized through Fireworks. Rakuten’s model was likewise reported to use DeepSeek-V3, while Harvey trained a legal model from Kimi K3 using 150 Nvidia B300 GPUs for two months, raising its full-pass rate on legal tasks from 10.8% to 19.7%. Thomson Reuters spent $40 million on a model called Snowdon, later identifying Alibaba’s Qwen3.5 as its base after additional calibration with Imperial College London. The article attributes this shift to the availability of downloadable weights, local data control and lower costs, while noting that licensing and model attribution remain sensitive issues. It cites OpenRouter data showing Chinese models accounted for more than 30% of U.S. company traffic each week after February, peaking at 46%. Pricing then moved in opposite directions: DeepSeek raised its flagship output price by 350% on August 17, while OpenAI cut its flagship price by 80% in the same week, yet downloads did not reverse and Kimi’s annualized revenue nearly tripled over three months. The article also describes possible policy responses: a U.S. senator proposed expanding restrictions to all Chinese models, China was consulting with several domestic companies about export controls on model weights, and Chinese firms had not signed an EU transparency code joined by about 190 organizations. It concludes that open weights already downloaded cannot easily be withdrawn, but future releases may become harder to access as controls, commercial fees and safety reviews increase.
