Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier in the agent category. The first one I'd give to a non-technical friend.
