China’s Moonshot AI Releases Model to Challenge Top U.S. Systems

China’s Moonshot AI has launched an artificial-intelligence model it says outperforms some cutting-edge U.S. systems, the latest sign that Chinese labs can rival American counterparts in critical technology frontiers.

Moonshot said Friday that it planned to fully open-source the model, called Kimi K3, by late this month, where people will be generally free to download and adapt. With 2.8 trillion parameters dictating its decision-making, Kimi K3 is the world’s biggest open-source model, according to the Beijing-based startup.
