Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
