Naver — Chuncheon Data Center (Gak)

Naver's Gak data center in Chuncheon, Gangwon Province, is South Korea's first and largest hyperscale data center operated by a domestic internet company. Opened in 2013, Gak serves as the primary training and inference site for HyperCLOVA X — Naver's 82-billion-parameter Korean-English large language model and the foundation of its CLOVA AI platform. The campus was designed by Naver's in-house architecture team with Korean summers and winters in mind, using free-air cooling during most of the year. The facility supports Naver Search, Naver Map, LINE messaging AI, and dozens of Clova AI services. A second phase expanded capacity to over 100 MW. Naver has invested in offshore wind PPAs in the Korean western sea to power the data center with renewable energy. Gak is the largest single deployment of AI compute for Korean NLP research globally, enabling Naver to compete with US hyperscalers in the Korean language AI space.
