Independent analysis of AI cost and value
Make AI investment economically legible
AI Economics Hub connects AI cost, evidence and business outcomes so leaders can decide what to fund, redesign, stop or scale.
AI cost is metered to the token; AI value usually is not measured at all. And as generating work gets cheaper, the limit on value moves to people's capacity to review and absorb it. This site shows how to price both, for finance, technology, FinOps and AI leaders. Claims are sourced, and the site's own frameworks are labelled as proposals, not standards.

Every station is a page. If you are new, start at Start Here and ride the System line. Ringed and linked stations are interchanges, where one line of thinking meets another; the dashed passage joins the two ways in.
Two ways in
Read the argument, or put it to work. Both draw on the same sources, and each page points to its counterpart in the other.
- The argument, the evidence and the modelsUnderstand
Why AI cost is visible and AI value is not, the models that explain it, the evidence, and the strongest arguments against the site's own positions.

- How to do it in the real worldImplement

Built to be challenged
AI economics is moving too quickly for false certainty. This site separates sourced evidence from interpretation, dates material claims, publishes corrections, and keeps a record of its own positions as the evidence changes.

AI tools are used in research, drafting and production under human editorial direction, and material claims are checked against the cited source before publication.
