[Emergency Episode] Moonshot’s Kimi K3 has Arrived! China has a Frontier Model

Moonshot’s Kimi K3 is presented as a frontier-level model that the hosts rank among the world’s top three, with benchmark strength but a noticeable user-experience gap versus leading closed models. The episode focuses on its 2.8T-scale serving constraints, delayed weight release, higher API pricing, Chinese accelerator strategy, and what the model says about the narrowing open-vs-closed gap.
