Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier in the agent category. The first one I'd give to a non-technical friend.
