Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
