- House committees are investigating the national security, cybersecurity, and economic security risks of U.S. companies using Chinese open-weight AI models, focusing on DoorDash.
- Open-weight AI models lack guardrails, making them vulnerable to misuse, such as code injection or attacks on AI systems.
- The investigation aims to gather facts to inform a federal approach that reduces reliance on Chinese models while promoting American open-weight alternatives with appropriate safeguards.
- Previous letters were sent to Anysphere and Airbnb in April 2026, and DoorDash is now requested to provide similar information.
