The control layer for every AI model

Work every model. Measure every model.

One place to run many AI models in parallel on your own keys — and a live exchange that grades them by the only number that matters: the real cost of a done task.

Free & open-source core · your keys, your machine · nothing is sold to you but the tools.

Every dashboard shows you tokens and latency. We show cost per verified task — and we're the interface you actually work through. As models multiply, the layer that measures, routes and switches them is where the value concentrates.

Three products, one layer

Each stands on its own. Together, they're the middleman for a world of many models.

The Arena

Why it matters

THE SHIFT
Models are a commodity now
Dozens of capable models, prices and quality moving weekly. Nobody knows which one to use for what — or what it truly costs.
THE GAP
Everyone measures the wrong thing
Tokens and latency don't tell you if the job got done, or what it cost including retries and reasoning burn. We measure the done task.
THE BET
Own the interface & the price
Be the layer people work through and the exchange that prices model work. The middleman for many models is a category, not a feature.
