   Report: ByteDance to Broadly Restrict Employees' Internal Personal-Paid Use of Claude, Codex and Others

   According to a tip from Dachang Ribao on November 3, ByteDance will broadly restrict the internal use of personal accounts for Claude, Codex and others; the notice, issued last week, sparked internal discussion. ByteDance Technical Vice President Hong Dingkun responded on the internal network that once L3-and-above content leaks, the consequences are very serious, and held that promoting a product should not rely on banning other options to force usage. Previously, in May 2025, ByteDance's security and risk control department had announced that starting June 30, 2025, third-party AI development software such as Cursor and Windsurf would be banned in batches, with Trae as the replacement.

   ByteDance to Broadly Restrict Employee Use of External AI Tools Such as Claude and Codex

   ByteDance will broadly restrict employee use of external AI coding tools such as Claude and Codex. Hong Dingkun, the person in charge, responded on the internal network that internal information security is an important consideration behind this adjustment, and that once L3-and-above content is leaked, the consequences are serious. The report notes that when external AI tools read a company's internal code repositories and technical documents, they may bring the risk of sensitive information being transmitted to third-party services.

   Report: ByteDance Restricts Employee Access to Internal Materials via External AI Tools Such as Claude and Codex

   According to a report by Dachang Ribao, ByteDance has introduced new internal rules on the use of AI tools. Starting this month, external AI access is banned for all L4-level code repositories and Feishu documents company-wide, and AI accounts purchased by employees themselves will no longer be able to access the relevant internal resources. ByteDance executive Hong Dingkun responded on the internal network that internal information security is an important consideration behind this adjustment, and that the consequences of any leak of L3-and-above content would be serious.
