Weaknesses	Still catching up on quality vs Kling/Runway Less control than pros need	Niche use case Pricing ramps fast	Not for full songs with vocals Shorter generation limits	Cold starts on less-popular models Pricing gets real at scale
Kai's verdict	A-tier if you already pay Gemini. B-tier standalone.	A-tier in its niche. The only one that actually gets emotion right.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier for open-source model APIs. The default in this space.
