ByteDance prepares a Muse-like AI agent for the coming weeks; Zhang Yiming sees parity with US labs only by 2029–2030

Bloomberg reports the co-founder told an all-hands meeting of AI staff that ByteDance's Seed pretraining data is orders of magnitude smaller than top US rivals'.
Why it matters
ByteDance is the most widely used Chinese consumer AI company through Doubao, but this is a rare admission from its founder that it trails US frontier labs on data, not just chips. A Muse-style agent would move ByteDance from chatbots to a voice assistant that carries out tasks, the category Meta opened with Muse in September. The timeline he gave is far longer than most Chinese lab messaging. Watch whether the agent launches within weeks as reported, and whether it ships outside China.
