Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
