Category	Dev Platform	Design	Image	Dev Platform
Pricing	Pay per token — model-dependent	Free + $20/mo	Included with ChatGPT Plus $20/mo	Pay per second of compute
Best for	Developers experimenting across models. Apps that want fallback logic.	Frontend devs, PMs prototyping UIs, anyone on Next.js.	ChatGPT Plus users who want images without paying extra.	Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	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	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy
Weaknesses	Slight markup over direct API Some provider features not exposed	Best for shadcn stack Iterating can be fiddly	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control	Cold starts on less-popular models Pricing gets real at scale
Kai's verdict	S-tier for model-shopping. I use this for every prototype before committing.	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.	S-tier for open-source model APIs. The default in this space.
