Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
