U.S. lawmakers have requested that food delivery company DoorDash provide information on its use of Chinese AI models. This move is part of a joint investigation by two House committees aimed at assessing the security implications of U.S. companies’ use of Chinese AI systems. Previously, reports indicated that DoorDash had outsourced some lower-level AI tasks to the Kimi K2.6 model developed by the Chinese company Moonshot AI. DoorDash is the latest company, following Cursor and Airbnb, to receive such a request for information, reflecting the U.S.’s growing scrutiny of Chinese AI models.
