Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for speed. When latency is the product, start here.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for builders. The right primitives. What Kai is built on under the hood.
