Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.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 open-source model APIs. The default in this space.
