Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for open-source model APIs. The default in this space.
