The right AI for the job. Measured, not guessed.

Independent, hands-on evaluation: benchmarks, live pricing, and self-hosting tradeoffs weighed in practice, so you know when the frontier model earns its cost, when a lighter system is enough, and when not to use AI at all.

Live data

Cost vs. quality across 15 benchmarks

Pick a benchmark below. Models on the dashed line are Pareto-optimal: no other model offers better performance for less money.

The promise

Spend where it changes the outcome. Not on the smallest model by default, not on the biggest.

Head-to-head

Compare models side by side

Pick any models you're evaluating and compare benchmarks, pricing, and specs in one view.
