Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.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.
