Kai's verdictB-tier. Still early. Manus is more flexible for less money.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.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
