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.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
