China's Moonshot Debuts Kimi K3, a 2.8T-Parameter Open AI Model

Moonshot releases Kimi K3, a 2.8-trillion-parameter open-weight AI model claiming competitive performance with US frontier models at significantly lower deployment cost. The release reflects China's accelerating open-model strategy, with multiple Chinese developers now closing the performance gap whilst undercutting US pricing on enterprise deployments. If you're selling AI infrastructure, tooling, or services to enterprises on top of proprietary US models, you're about to compete on cost against open-weight systems that run at a fraction of OpenAI's price. The moat was always performance; now China has performance and a 10x cost advantage.
