❯ Two House Committees Probe DoorDash’s Use of Moonshot AI’s Kimi Model for Coding; Documents Due August 14

COMMITTEES CALLThe House Select Committee on China and the Committee on Homeland Security have sent a letter to DoorDash CEO Tony Xu over the company’s use of Chinese models, demanding a full inventory of Chinese models in use and security-test records by August 14, and requiring the relevant executives to appear before Congress by August 21. DoorDash is the largest food-delivery platform in the United States.

SELF-DISCLOSUREThe evidence cited in the letter comes from public statements — co-founder Andy Fang previously said the company had connected open-weight models to its internal AI-assisted code-review system. The approach is tiered: harder tasks go to U.S. frontier models, while lower-level work goes to Moonshot AI’s open-weight model Kimi K2.6. Lawmakers also cite the White House Office of Science and Technology Policy, which says Moonshot AI operated a covert platform, conducted large-scale distillation of U.S. models, and used an unauthorized advanced-computing system — allegations that have not been confirmed by any court or independent third party. The investigation began in April and has already examined several other U.S. companies’ use of Chinese open-weight models.

COMPLIANCE COSTSThe trouble is that the original selling point of open-weight models was that they can be downloaded, run locally, and send no data back — technically more controllable than calling overseas APIs. But Congress is not asking about data flows; it wants to know whose models actually ran in the codebase. U.S. companies’ technology-selection processes must add a review that never existed before: the model’s nationality. For Chinese model vendors, the overseas installation base generated by open-sourcing is becoming a liability — the broader the adoption, the more instances get named.
