Upstage is a Seoul-based enterprise AI company. It releases some Solar models as open weights under custom or permissive licences and sells its flagship Solar Pro models through an API and on-prem. It claims SOC 2, ISO 27001 and ISO 27701 certification and says API data is not stored or used for training. It also runs a California subsidiary, so the catalogue's 'no CLOUD Act exposure' flag should be reviewed. Further gaps are no verified EU presence, no confirmed GPAI Code of Practice signature, and a January 2026 dispute over whether Solar Open 100B was built from scratch (Upstage denies the claim).
