Kai's verdictA-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
