Kai's verdictS-tier. Category leader. Nothing else is close yet.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.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.
