HAMi Moves to CNCF Incubating Stage
We are excited to announce that on July 2, 2026, HAMi was accepted as a CNCF Incubating project, with the CNCF Technical Oversight Committee passing the incubation vote unanimously in favor.
This is an important milestone following HAMi joining the CNCF as a Sandbox project in August 2024. It means the CNCF Technical Oversight Committee (TOC) recognizes HAMi's mature technical and security practices, active community, real production adoption, and open ecosystem integration.
Our sincere thanks to CNCF TOC Chair Karena Angell, who led the due diligence, TOC member Kevin Wang, TAG-Runtime for its technical review, and all the adopters who shared their insights.
HAMi is a heterogeneous compute virtualization and scheduling middleware for Kubernetes. Through container-level hard isolation, it finely partitions GPU memory and compute so that multiple workloads can safely share a single accelerator. Founded by maintainers Xiao Zhang and Mengxuan Li, it is built by developers worldwide under CNCF governance.
Today, HAMi is used by hundreds of organizations across a dozen-plus accelerators including NVIDIA, Ascend, Cambricon, Hygon, Moore Threads, Enflame, Kunlunxin, MetaX, AWS Neuron, and Vastai (see the supported device list). CNCF case studies document production practices at China Merchants Bank, SNOW Corp., NIO, KE Holdings, DaoCloud, SF Technology, and PREP EDU, spanning finance, automotive, mobility, logistics, education, and cloud services. HAMi-core integrates with the Kubernetes default scheduler, Volcano, Kueue, Koordinator, and the KAI Scheduler.
This milestone was made possible by a global community of nearly 500 contributors from dozens of countries. Dynamia, DaoCloud, 4Paradigm, NVIDIA, and Huawei Cloud, together with many individual developers, user enterprises, and ecosystem partners, have each made irreplaceable contributions.
Entering Incubation is a higher starting point. The community will keep investing in upstream R&D, ecosystem adaptation, and production-grade deployment, working with global partners to make HAMi the open infrastructure for heterogeneous compute management in the AI era.
