ByteDance has internally prohibited the use of AI programming tools such as Cursor.
ByteDance Bans AI Programming Tools like Cursor Internally
On Wednesday, ByteDance's security and risk control department sent an email stating that, considering the prevention of data leakage risks, starting from June 30, third - party artificial intelligence development software will be phased out and banned internally, including AI programming tools such as Cursor and Windsurf. ByteDance's in - house programming assistant Trae will be used as an alternative. Trae is an AI programming tool released by ByteDance in March this year. It is powered by the base large - model doubao - 1.5 - pro and supports switching to the full - blooded version of DeepSeek R1&V3. It is the first AI - native IDE (Artificial Intelligence - Native Integrated Development Environment Tool) in China. The overseas version of Trae has also been launched, and a paid subscription plan was officially introduced in May. ByteDance has not responded officially yet.
