Kai's verdictA-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
