Moonshot pauses Kimi K3 signups after demand maxes out GPUs in 2 days

Moonshot AI has temporarily halted new subscriptions to its Kimi K3 model after demand nearly exhausted its GPU capacity within 48 hours of launch. The company says it plans to split its subscription tiers to better distribute compute across users.

Why it matters: This is a concrete signal that the open-weight Kimi K3 release is drawing real user demand, not just strong benchmark scores — Moonshot's compute crunch shows a Chinese lab can now trigger a launch-demand spike similar to major US model releases, while also revealing that its infrastructure headroom is thinner than a well-funded US lab's.
