China’s Moonshot AI has made its latest artificial intelligence model Kimi K3 available for public download, as its open-source strategy and more support for non-Nvidia ecosystems trigger heated debates across Silicon Valley.

On Monday, the Chinese AI start-up not only released the model’s “weights” – the underlying parameters that encode its intelligence – but also made available key infrastructure, including tools to improve efficiency and stability.

The move has allowed developers around the world, including in the United States, to use, copy, modify and distribute the software – the largest open-weight AI model so far with 2.8 trillion parameters.

The company has not disclosed the AI chips it used for training, but domestic hardware options are quickly becoming available.

The cloud unit of Alibaba Group Holding said its supernode powered by proprietary Zhenwu M890 chips was compatible with Kimi K3, while a computing platform powered by Huawei Technologies’ Ascend 910C also completed adaptation. Alibaba owns the South China Morning Post.

Moonshot itself is diversifying beyond the Nvidia ecosystem.
