Kai's verdictS-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier inside Photoshop (Generative Fill). B-tier standalone.
