[ByteDance reportedly restricts the use of external AI tools such as Claude and Codex] November 4th: According to an internal notice, ByteDance plans to restrict employees from using external AI tools such as Claude and Codex on a large scale starting this month. The company's L4 level code warehouse and Feishu documents will be prohibited from external AI access, except for some Seed scenarios. Even AI accounts purchased by employees at their own expense will no longer be able to access these restricted content. Hong Dingkun, vice president of technology at ByteDance, later responded in detail on the intranet. On the one hand, he bluntly stated that "Once L3 and above content is leaked, the consequences will be very serious." On the other hand, he also frankly said: "Promoting products does not need to use this method of banning other options and forcing use, because the effect is very poor." (Titanium Media)
