The K3 launch is a capacity-planning case study. Here is an admission gate for your own AI service before demand surprises you.
Kimi K3 launched on July 16. By July 19, Moonshot AI suspended all new consumer subscriptions because user requests exceeded cluster capacity within 48 hours.
This is not a Kimi problem. It is a capacity-planning lesson for anyone operating an AI-backed service.
