Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for speed. When latency is the product, start here.S-tier for text-in-image. Use this for posters, Midjourney for art.
