The TKX is a capability-adjusted index — quality and cost, task by task — so a token from one provider can be valued against another. It is live.
| Series | |
|---|---|
| TKX (GENERAL) | 102.1 Grounded |
| TKX-OPEN | 123.0 Grounded |
| TKX-FRONTIER | 100.1 Grounded |
As of 2026-09-13, the TKX is 102.1, meaning a unit of AI capability is at a premium to the 2026-08-04 baseline of 100.

Every model is scored across four task families — reasoning, code, extraction, high-volume classification — against its blended price. The output is a value-per-dollar score and a fair exchange rate between models, refreshed as models and prices change.
| Model class | Quality | Blended $/M | TKX value |
|---|---|---|---|
| Frontier reasoning | 96 Provisional | $20.00 | 48 Provisional |
| Workhorse general | 89 Provisional | $11.90 | 75 Provisional |
| Volume / fast | 76 Provisional | $2.38 | 100 Provisional |
| Open-weight blend | 72 Provisional | $1.65 | 96 Provisional |

Crude couldn't trade globally until it was graded. Electricity, bandwidth, and computing power followed the same path: a vital, volatile input becomes a market the moment there's an agreed unit to measure it by. AI tokens have the scale, the cost, and the volatility — the TKX supplies the unit.
Answer the question every finance team is asking: are we paying a fair price per unit of intelligence? Govern spend against the index, compare every model's value on one scale, and negotiate with a reference in hand.
As computing power financializes on the world's major exchanges, contracts need a credible token benchmark to reference. The TKX is built to be that reference — published methodology, an equal-weighted basket (consumption-weighting later), and licensing for exchanges, banks, and trading desks.
