Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for open-source model APIs. The default in this space.
