U.S. lawmakers request information from DoorDash on use of Chinese AI models

U.S. lawmakers are investigating American companies like DoorDash for using Chinese AI models, citing national security concerns as China's AI capabilities improve. DoorDash stated it uses Chinese model Kimi K2.6 (developed by Moonshot AI) for lower-level tasks because it offers better performance and lower costs than some U.S. alternatives, though the company says it prioritizes American AI development. The investigation focuses on risks from depending on AI systems developed by entities under Chinese government jurisdiction, even though U.S. companies are not currently prohibited from using these models.
