Why we built Kosha.
We pick models for client systems every week, and the specs we need are scattered across a dozen provider pages that never agree on format.
So we built the reference we wanted: one open index where context windows, pricing, and capabilities sit in the same columns for every model. We check Kosha in our own work every day.
It is free and open for you too, because a model reference should cost you nothing to read.
