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.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
