Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
