Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for sales teams. B-tier for solo users.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
