Phoenix Tech News (Editor/Yu Lei) On November 4, according to a report by Dachang Ribao, ByteDance recently issued new internal regulations on the use of AI tools, which will broadly restrict employees from using external AI tools such as Claude and Codex via personal accounts to access the company's internal materials. It is reported that starting this month, ByteDance will impose an external AI access ban on all L4-level code repositories and Feishu documents across the entire company, and AI accounts purchased by employees themselves will no longer be able to access the relevant internal resources.
In response to employees' questions, ByteDance's relevant person in charge, Hong Dingkun, gave a detailed response on the company's internal network. He emphasized that internal information security is an important consideration behind this adjustment, saying that "once L3-and-above content is leaked, the consequences are very serious."
In recent years, AI programming tools such as Claude and Codex have gradually become an important part of developers' daily work. Some developers use the relevant services through personal subscription accounts to assist with code writing, debugging, and project development. However, when external AI tools need to read materials such as a company's internal code repositories and technical documents, they may also bring the risk of sensitive information being transmitted to third-party services.
