## Summary

ByteDance Doubao public relations head Liu Xing says rumors that Hengdian gave 150,000 extras' portraits and voices to ByteDance's large model are seriously false. Liu says Volcano Engine is only the technical support provider in the Hengdian film AI service platform project, that all data assets belong to Hengdian or its licensors, and that the data will not be used to train ByteDance models. Public information shows the project is in the bidding award stage.
