Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
