## Summary

ByteDance has restricted employees from using personally purchased third-party AI accounts such as Claude and Codex to access L4-level code repositories and Feishu documents, according to reports. The restrictions, which began in early November, are being rolled out in phases, with some Seed team use cases exempt. Hong Dingkun, ByteDance's vice president of technology, said data security was the main driver and denied that the move forces employees onto the company's own tools.
