 "famous_for": "AI factory campus: 5,001 MW IT, 2,681,856 GPUs, PUE 1.17 — designed by us, checked by the engine",
 "story": "An imagined AI factory on empty land on the US Gulf Coast: 8 halls, 388 identical pods of 96 GB200 NVL72 rack systems, 2,681,856 GPUs. The grid arrives at 400 kV; gas turbines and batteries carry it through outages. Each pod's racks are cooled 70 % by liquid (CDUs to dry coolers) and 30 % by air. At a summer afternoon the engine finds 5,001 MW of IT, PUE 1.17 and 11,146 million tokens a second from a 70B model — and 21.6 million tonnes of CO₂ a year on today's grid mix.",
 "notable": [
  "388 pods × 96 GB200 NVL72 rack systems (120 kW each from the catalog) = 2,681,856 GPUs.",
  "Per pod the engine sees 12,888.4 kW IT, 15,100.5 kW facility, PUE 1.17 and 28,726,819 tokens/s at the design afternoon.",
  "24 CoolIT CHx750 CDUs per pod carry 70 % of the heat as liquid; Vertiv Liebert CW CRAHs take the rest.",
  "A year at 0.065 USD/kWh: $3336 M for 51,324,840 MWh; 21,556 kt CO₂ at 420 g/kWh.",
  "Catalog list prices cover 5 of 8 part types per pod; the GB200 NVL72 has no list price in the catalog, so the BOM leaves it out."
 ],
 "assumptions": [
  "Scale: 5,000 MW IT target from the brief (IMAGINED-GIANTS.md §1); the pod count is that target ÷ the engine's pod IT load.",
  "Rack system: catalog record rack_system/nvidia/gb200-nvl72, 120 kW IT, 72 GPUs, 70 % liquid-cooled (catalog thermal data).",
  "Cooling: cdu/coolit/chx750 CDUs (750 kW, catalog) in loops of 3 per row, N+1; heat rejected to dry coolers; crah/vertiv/liebert-cw CRAHs (120 kW) on a chilled-water plant for the air share.",
  "Power: 2N from a 400 kV substation through ATS (grid / genset bank), transformers, switchboards and MW-class UPS banks (generic nodes: no MW-class UPS in the catalog), busway taps per rack; standby genset banks of Cat 3516C (2 MW standby, catalog); on-site gas turbines + batteries (sized as the genset bank in the model).",
  "Climate: a July day at 29 °C mean with a 9 °C daily swing and 70 % RH (typical July climate for the region); the numbers are read at 15:00 local, the warmest hour.",
  "Grid factor 420 g CO₂/kWh and tariff 0.065 USD/kWh: dc-world/reports/giants-references.md §2 / §3.",
  "Tokens: every rack serves a 70B chat model at 70–95 % load (engine estimate from GPU memory bandwidth and FLOPS; labelled estimated, not a benchmark).",
  "Water: closed-loop dry coolers, no consumptive water (evaporative trim not modelled).",
  "Estate: the DR and peer sites, link capacities and carriers are part of the imagined design, not real contracts; latency is estimated from distance.",
  "References for scale, cooling and power patterns: §1.1 Stargate Abilene (scale, DLC + CDUs, PUE 1.12–1.15); §1.2 Hyperion & Prometheus (GW campus, 500 kV, gas backstop); §1.3 Colossus (on-site turbines + BESS, 100k GPUs in one fabric); §2.1 ERCOT grid factor ~400 g/kWh and ~$0.065/kWh (dc-world/reports/giants-references.md)."
