Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
