The exchange for
AI inference
A public price, a certified quality floor, and a cleared trade. For every inference token bought and sold.
The problem
Inference has buyers and sellers.
It does not have a market.
Buyer
You cannot tell a fair price from an arbitrary one.
OpenAI, Anthropic, Google and others price unilaterally, and there is no
benchmark to check them against.
Seller
A GPU sitting idle earns nothing.
There is nowhere to sell spare capacity, and no contract that would make a
corporate buyer accept it if there were.
Market
The price never moves.
Published rates sit still for months while supply and demand shift underneath
them. A rate card is not a market.
Oil traded this way for decades, until Brent.
The solution
An exchange.
KRRKappa Reference Rates
A public reference rate, computed only from cleared trades
KVSKappa Voluntary Standard
Graded C·B·A on how far a node diverges from an
open-weights reference
KX MatchRouting engine
Blind matching in under a millisecond.
The price picks the node, nobody chooses a supplier
Clearing
The venue stands behind the trade. Every completion settles at a fee, and if the
winning node fails the order moves to the next ask
while the buyer still pays the first price
Four protocols. The venue owns none of the compute it clears.
