The early-stage project would be about three times larger than Moonshot's Kimi K3 and extends ByteDance's strategy of accepting short-term LLM lag while pursuing independent development.
ByteDance is reportedly pre-training an AI model that may reach 10 trillion parameters, a scale that would make it about three times larger than Moonshot AI's Kimi K3, China's largest released AI model, and potentially comparable to Anthropic's most advanced Mythos systems. The project remains in an early stage, with pre-training typically lasting three to six months before ByteDance decides the model's final size, potential fine-tuning and any release. The effort reinforces ByteDance's stated preference for independent development: founder Zhang Yiming has urged the AI team to pursue a world-class model rather than short-term competition, while CEO Liang Rubo has said the company's core LLMs are falling further behind top overseas rivals. ByteDance has nonetheless built strong positions in applications, with Doubao leading China's consumer AI market at 324 million monthly active users, SeeDance viewed as one of the world's most advanced video-generation models, and tighter ties among Doubao, Feishu and Volcano Engine helping enterprise sales.
