Kai's verdictS-tier for local inference. If you care about privacy or want to tinker, install this today.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
