Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
