Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-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.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
