China’s ByteDance has begun work on a frontier-scale AI model that could reach 10 trillion parameters, according to people familiar with the effort cited by the Financial Times. The target would make the system roughly three times the size of Moonshot’s Kimi K3, currently the largest Chinese model released.
At that scale the project would land near Anthropic’s top-tier systems, which outside analysts estimate at about 8 trillion parameters for Mythos and 5 trillion for Fable 5. ByteDance has not disclosed when pretraining might finish or when a model could ship.
The move reads as a positioning play as much as an engineering milestone. Chinese labs are working to close the gap with US frontier models, and ByteDance, the owner of TikTok and Douyin, brings rare compute and data advantages to the race. Its consumer chatbot Doubao has so far competed mainly on price, so a maximal-scale flagship would be a notable strategy shift.
Runs of this size carry enormous cost and power demands, and the final parameter count could change as pretraining proceeds. Even so, the disclosure is the clearest signal yet that China’s largest internet companies intend to meet the US at the frontier instead of competing purely on cost.
