Weaknesses	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Not for full songs with vocals Shorter generation limits	Cold starts on less-popular models Pricing gets real at scale	Needs beefy laptop for larger models Speed way behind cloud APIs
Kai's verdict	B-tier. Still early. Manus is more flexible for less money.	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.	S-tier for local inference. If you care about privacy or want to tinker, install this today.
