Kai's verdictS-tier for speed. When latency is the product, start here.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
