Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for local inference. If you care about privacy or want to tinker, install this today.
