Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-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.
