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 | Reading |
|---|---|
| TKX (GENERAL) | 102.0 Grounded as of 2026-10-20 |
| TKX-OPEN | 107.7 Grounded as of 2026-10-20 |
| TKX-FRONTIER | 100.1 Grounded as of 2026-10-20 |
As of 2026-10-20, the TKX is 102.0, meaning a unit of AI capability is cheaper than the 2026-08-04 baseline of 100.

Latest membership change (2026-09-25): Muse Spark 1.3 was added to the TKX.
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 |
Class examples only. Source: Cambent TKX. The index is live — methodology published and tracked.
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.
See your cost per unit of capability against an independent benchmark. 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.
