Moonshot paused new Kimi K3 subscriptions just three days after launch, as demand for its large open model exceeded available GPU capacity. This immediate compute bottleneck emerged as China's Xi Jinping publicly backed open-source AI and Alibaba teased a 2.4T open-weight Qwen 3.8 model. Meanwhile, Axios reported that Washington may ban Chinese AI models, suggesting future bottlenecks could shift to regulatory permission for open-weight models.
The rapid sellout of Kimi K3's GPU capacity confirms that compute supply remains the immediate binding constraint for new model deployments.
