Model the AI infrastructure buildout.
Interactive calculators, scorecards, vendor screens and diligence workbenches. Every tool is anchored to the parent essay's framework, sized against real hyperscaler disclosures and OCP specs, and configurable slice-by-slice. Scenario framework for architecture comparison and investment analysis. Not vendor design guides.
Reader path. Each tool sits alongside a parent essay that explains the architecture and defends the anchor values. Click through to the tool for scenario work; click the "Read the parent essay" link inside to see the underlying analysis.
CoolingData centre cooling economics
Rack density, redundancy, phase and coolant temperature drive CDU sizing, capex, opex and TCO. Anchored to Fig C15 of the parent DTC essay.
Calculator · Capex + Opex + TCO
DTC cooling capex, opex + TCO calculator
Sizes CDU count and models per-rack capex, year-1 opex and 7-year TCO across free-cooling and two-phase switches. 3×3 sensitivity, URL-hash sharing, Markdown export.

Scorecard · Risk pattern
AI Power Chain risk scorecard
Scores a target's exposure to five AI Power Chain risk vectors: qualification cycle, standards adoption, hyperscaler concentration, chokepoint capture, geopolitical.
Five-vector risk model · companion to the vendor screen
Due diligenceDD framework tools
Evidence matrices and question banks from the Due Diligence for the AI Buildout framework.
Reference · Evidence classification
DD Evidence Matrix
Canonical evidence classification for AI-infrastructure diligence: Published, Derived, Management-provided. Maps every workstream question to the tier a serious sponsor should accept.
