Strengths	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Ships working React + Tailwind code Shadcn/ui native One-click deploy to Vercel	Excellent prompt understanding Built into ChatGPT — no extra subscription Good at composition + concepts
Weaknesses	Cold starts on less-popular models Pricing gets real at scale	Not for full songs with vocals Shorter generation limits	Best for shadcn stack Iterating can be fiddly	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control
Kai's verdict	S-tier for open-source model APIs. The default in this space.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier. If you're on Vercel/shadcn, this is cheating.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
