Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. S-tier if you self-host. The reason open-source image gen matters.
