According to news from Dachang on November 3, Byte has introduced new regulations that will broadly restrict the internal use of personal accounts such as Claude and Codex. According to the news, starting this month, ByteDance will ban external AI access to all L4 level code warehouses and Feishu documents, covering the entire company, and AI accounts purchased by individual employees can no longer be used. The news also said that since the notice was issued last week, it has caused some internal discussions. Hong Dingkun, vice president of ByteDance technology, also made detailed responses on the intranet, such as “once L3 and above content is leaked, the consequences are very serious” and “there is no need to use this method of prohibiting other forced use of products, because this is very poor.”
