Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for text-in-image. Use this for posters, Midjourney for art.
