Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for designers. The only one that takes vectors seriously.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for open-source model APIs. The default in this space.
