Kai's verdictS-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for text-in-image. Use this for posters, Midjourney for art.
