Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.A-tier in its niche. The only one that actually gets emotion right.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
