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. [domestic hardware options](https://www.scmp.com/tech/tech-war/article/3361048/alibaba-targets-nvidias-dominant-software-ecosystem-open-source-ai-stack?module=inline&pgtype=article)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.
