The Severgrad Computational Complex (SCC) is the Soviet Union’s first purpose-built artificial intelligence infrastructure city, located at 68°14′N, 86°03′E in Krasnoyarsk Krai, approximately 340 km north-northeast of Norilsk. Commissioned 1 April 2025 after thirty-one months of construction, it is operated by the Institute of Computational Systems and Artificial Intelligence (ICSAI).
The SCC encompasses a Compute Campus (14 halls, 2.4 exaflops FP16 combined accelerator capacity running Loongson 3C7000 accelerators), the Ob-Yenisei Hydroelectric Substation (2,200 MW from the Yenisei cascade supplemented by a 600 MW thorium molten salt reactor), residential housing for 12,000 personnel and families (District Akademiya), a cryothermal cooling network achieving PUE 1.06 and WUE 0.08 L/kWh, and a dedicated logistics hub (Severport). At full load the Complex consumes approximately 1.8 GW, with 97% from zero-carbon sources.
It hosts primary inference and fine-tuning infrastructure for the RAZUM model family (including the RAZUM-Next programme targeting 400B–1T parameter models) and the Union AI Safety and Alignment Laboratory (UASAL). Severgrad is distinct from conventional datacenters in being designed from the ground up as an integrated scientific city — computation, energy generation, and residential infrastructure co-located at a latitude chosen for thermodynamic efficiency rather than logistical convenience.
