Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
