Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Advanced Voice Mode feels genuinely conversational Realtime API enables true two-way voice apps Built into ChatGPT	Ships working React + Tailwind code Shadcn/ui native One-click deploy to Vercel	Prompt-to-UI with real layouts Exports to Figma Faster than hand-designing from scratch
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Pricey for production apps Less voice variety than ElevenLabs Platform lock-in	Best for shadcn stack Iterating can be fiddly	Output needs designer polish Pricing unclear / changes often
Kai's verdict	B-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.	S-tier. If you're on Vercel/shadcn, this is cheating.	B-tier. Useful for first drafts. v0 is the better bet for shipping code.
