Moonshot AI trained its Kimi K3 large-language model using a cluster of roughly 20,000 Nvidia chips provided by Alibaba Group Holding Ltd. [1]

The arrangement highlights the intense compute requirements for frontier AI development and the strategic partnerships Chinese startups form to access restricted hardware. By leveraging Alibaba's cloud infrastructure, Moonshot AI can compete with both U.S. AI offerings and the internal models developed by Alibaba itself.

The Beijing-based startup utilized a cluster consisting of approximately 20,000 Nvidia Hopper H200 GPUs [1, 2]. These chips were supplied through a computing agreement with Alibaba's cloud platform [1]. While some reports identify the hardware as H200s [2], Alibaba said it would not confirm the exact chip type, acknowledging only the existence of the deal [1].

Moonshot AI developed the Kimi K3 model to establish a competitive edge in the global AI landscape. The startup sought the massive compute power necessary to build a frontier model capable of challenging high-end systems from the U.S. and Alibaba's own Qwen series [1, 3].

The training took place on Alibaba's cloud infrastructure, which is located in China [1, 2]. This partnership allows Moonshot to scale its operations without owning the physical hardware, a critical advantage given the difficulty of procuring high-end Nvidia chips in the region.

Industry analysts said the arrangement is ironic, as the compute power provided by Alibaba was used to create a model that now rivals Alibaba's own AI products [3].

This partnership underscores a growing trend of 'compute-as-a-service' in China, where a few giant cloud providers act as the primary gatekeepers for restricted high-end hardware. By providing the infrastructure for Kimi K3, Alibaba has effectively fostered a competitor to its own Qwen models, suggesting that cloud revenue and ecosystem growth are currently outweighing the risks of supporting rival AI startups.
