Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
