美国议员调查 DoorDash 使用 Moonshot AI 的 Kimi K2.6 模型

此举凸显了美国立法者与行业之间日益加剧的紧张关系：随着希望降低 AI 采用成本，美国公司正越来越多地使用中国 AI 模型。

众议院中国问题特别委员会主席 John Moolenaar 与众议院国土安全委员会主席 Andrew Garbarino 周五致函 DoorDash 联合创始人兼首席执行官 Tony Xu，要求该公司在 8 月 14 日前提供其使用的每个中国模型的信息，以及针对这些模型开展的所有安全测试。

信函还要求，负责 DoorDash“AI 基础设施、软件安全、模型评估、采购以及法律或合规审查”的员工，在 8 月 21 日前与议员进行现场简报。

中国的新 AI 模型 Kimi K3 会不会带来又一个 DeepSeek 时刻？

信中表示：“委员会认识到，从大型科技公司到初创企业，美国公司可能会评估并部署由中国开发的开放权重模型，因为这些模型能够提供有竞争力的能力、更低的成本、更强的定制化，以及替代依赖少数专有模型提供商的选择。”

“这些现实考量并不能免除采取基于风险的保障措施的必要性，也不会降低对于日益依赖受中国司法管辖实体开发的模型所引发的国家安全担忧。”

The move underscores growing tensions between US lawmakers and industry, as Chinese AI models have become increasingly popular among US companies looking to save costs of AI adoption.

House Select Committee on China chairman

and House Committee on Homeland Security chairman Andrew Garbarino sent a letter on Friday to DoorDash co-founder and chief executive Tony Xu, requesting information by August 14 on each Chinese model DoorDash uses and any security tests conducted on those models.

The letter also requests that DoorDash staff “with responsibility for DoorDash’s AI infrastructure, software security, model evaluation, procurement, and legal or compliance review” appear for an in-person briefing with the lawmakers by August 21.

Will China’s new AI model Kimi K3 create another DeepSeek moment?

“[The] Committees recognise that US companies, from large technology firms to start-ups, may evaluate and deploy PRC-developed open-weight models because they can provide competitive capabilities, lower costs, greater customisation, and alternatives to reliance on a small number of proprietary model providers,” the letter said.

“Those practical considerations do not eliminate the need for risk-based safeguards or diminish the national security concerns associated with growing dependence on models developed by entities subject to PRC jurisdiction.”
