Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier. S-tier if you self-host. The reason open-source image gen matters.
