Kai's verdictS-tier for open-source model APIs. The default in this space.A-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. Category-defining UX. If you take notes in meetings, switch this week.
