The index family cuts the same market several different ways. This page is where those cuts are checked against each other and against the alternatives they were chosen over — not where you'd come to read today's number. Each panel below states the question it answers before it answers it.
Compare segments
Daily index points on one scale, 100 on the base date. Each panel splits the same market a different way, so each keeps the broad index as its reference line.
Answers When the market is split by token-ranked capability, by who controls the weights, and by model-count-ranked capability, do the three splits move together, or does the choice of cut change the story?
By capability · tokens
AA tiers ranked by consumed tokens
By weights
Open weights against proprietary
By capability · models
AA tiers ranked by model count
Is Frontier just Proprietary by another name?
Membership of the High-capability tier, split by who controls the weights, from the latest quarterly review.
Answers The two-tier capability cut under discussion (Frontier vs. the rest) ranks by score; the open/proprietary split ranks by who controls the weights. Are they secretly the same cut?
Where the bill's exposure sits
The broad basket's tokens against its dollar cost, split by who controls the weights.
Answers Most tokens flow through open-weights models — does that mean most of a bill's risk does too, or does it sit somewhere else?
Spreads
Today's basket cost, one segment against another — a spread is a ratio of two already-published numbers, nothing new stored.
Answers How much more does the frontier cost than the rest of the market, and open-weights cost less than proprietary, in one number each, updated daily?
Coming next. Two more comparisons belong on this page once they're built to the same standard as the ones above: how a creator-set price (an event, tracked as a change log) differs in kind from a competitively-discovered one (a level, tracked daily); and a cost-of-capability curve showing what a capability floor costs across the whole market, for readers deciding what to buy rather than watching an index move.
