Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
