Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for speed. When latency is the product, start here.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
