Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for text-in-image. Use this for posters, Midjourney for art.
