Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier. Category-defining UX. If you take notes in meetings, switch this week.A-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
