Team Naver said on Thursday it has completed construction of an AI computing cluster based on 4,000 units of Nvidia's next-generation B200 (Blackwell) GPUs.

It said the infrastructure secures global-level computing power while laying the groundwork to advance its proprietary foundation model and flexibly apply AI technology across services and industry.

The company said Team Naver commercialised Nvidia's supercomputing infrastructure SuperPod in 2019 faster than anywhere in the world, and has since built up verification experience by designing and operating ultra-high-performance GPU clusters on its own.

The company said the newly built "B200 4K cluster" has computing scale comparable to top-ranking supercomputers on the global TOP500 list.

Internal simulations showed that training a model with 72 billion (72B) parameters took about 18 months on its existing A100-based main infrastructure of 2,048 units, but could be cut to about 1.5 months on the "B200 4K cluster".

With training efficiency improving by more than 12 times, Team Naver said it has established a development and operations system that can raise model quality through more experiments and iterative training and respond more quickly to a changing technology environment.

Team Naver said it plans to speed up ongoing work to advance its proprietary foundation model based on the infrastructure. It plans to scale up large-scale training of an Omni model that processes images, video and voice as well as text, raise performance to a global level, and apply it step by step across a range of services and industrial sites.

Naver CEO Choi Soo-yeon said, "This AI infrastructure build is meaningful not just as a technology investment, but because it has secured a core asset that supports the foundation of national AI competitiveness and AI self-reliance and sovereignty." She said, "Based on infrastructure that enables fast training and iterative experimentation, Team Naver will apply AI technology more flexibly to services and industrial sites to create tangible value."
