Moonshot Pauses Kimi K3 Subscriptions for 2.8 Trillion-Parameter Model as Demand Swamps GPU Capacity

Summary
Moonshot halted new Kimi K3 subscriptions on Sunday after demand for the newly launched multimodal model quickly exceeded serving capacity, while existing users remained protected.
Kimi K3’s scale and benchmark results drove the rush: the 2.8-trillion-parameter open-weight model was described as performing on par with Anthropic’s Opus 4.8 and OpenAI’s GPT 5.5 across many tests.
Developers and investors said the pause signals real product-market fit for frontier open models, with lower model costs likely to spur more inference demand rather than reduce infrastructure spending.
The launch also intensified debate over AI policy and openness, with critics and supporters arguing over whether strong Chinese open-weight models weaken the case for tighter pre-release controls on U.S. labs.
