Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
