# ByteDance Training 10-Trillion-Parameter AI Model to Rival Anthropic's Mythos

> ByteDance is reportedly pre-training a 10-trillion-parameter model, a scale meant to put it in the same conversation as Anthropic's Mythos 5, estimated at around 8 trillion parameters. If the reports hold, the model would be more than three times the size of Moonshot's 2.8-trillion-parameter Kimi K3, staking out a clear scale lead among Chinese labs. Pre-training is said to take three to six months. The move cuts against a prevailing narrative. Much of 2026 has been about squeezing more from smaller models and better training rather than brute-force scale, yet ByteDance is betting that raw size still buys frontier capability. It is a reminder that the scaling race is not over, it just moved. The bigger story is geopolitical. A Chinese consumer giant chasing the largest models in the world underscores how the US-China AI contest has become a matter of national capability, not just product competition. Whether a 10-trillion-parameter model actually outperforms leaner rivals is the open question, and an expensive one to answer.
