Kai's verdictS-tier for speed. When latency is the product, start here.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
