Kai's verdictS-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
