U.S. lawmakers are investigating DoorDash over its use of Chinese AI models， as Washington increases scrutiny of American companies adopting China-developed AI systems. A House committee inquiry requested documents on DoorDash's evaluation and deployment of Chinese models， citing founder Andy Fang's post about using Moonshot AI's Kimi K2.6 for lower-level AI tasks. DoorDash's AI research lab had said on X that it had seen Kimi K2.6 and Anthropic's Fable 5 vastly outperform other Anthropic models it had used， including "Sonnet 4.6 and Opus 4.8 harness at a cheaper cost." The debate highlights a growing AI rivalry： U.S. companies are increasingly testing Chinese open models as alternatives to expensive closed systems from OpenAI and Anthropic.
美国议员正调查DoorDash使用中国AI模型的情况，众议院委员会要求其提供评估和部署中国模型的文件。DoorDash AI实验室此前称，Kimi K2.6和Anthropic Fable 5在性能上远超其使用的Sonnet 4.6和Opus 4.8，且成本更低。此事凸显美国企业日益将中国开源模型视为OpenAI和Anthropic高价闭源系统的替代方案。
