Where the book uses it

• Chapter 4 — One Rack

  How a datacenter is actually built, from a converted factory in Memphis to a greenfield campus in Texas, and what the clock from first ground to first power really measures.

• Chapter 9 — The Price of Permission

  Who gets to say yes or no to a campus: counties, air regulators, courts and legislatures, and what their permits, abatements and refusals cost in time and money.

• Chapter 10 — The Lender’s Decision

  Who is lending the money and who bears the loss: the bonds, leases and guarantees behind the largest campuses, and how the paper reaches ordinary retirement accounts.

The model also achieves roughly 2x the token efficiency of comparable leading models, solving tasks in under half the number of steps”; the same page claims “twice greater token efficiency than the latest leading models at the same tasks” and, in a chart caption, that Grok 4.5 “resolves tasks with 15,954 output tokens on average, about 4.2× fewer than Opus 4.8 (max) at 67,020” on SWE Bench Pro, so the page states the claim three times against three denominators; the page dates itself “Jul 16, 2026”; read live 19 September 2026, unchanged).
