Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for speed. When latency is the product, start here.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
