Pricing	Included with ChatGPT Plus $20/mo	Pay per token — model-dependent	Free tier + pay-as-you-go	Pay per second of compute
Best for	ChatGPT Plus users who want images without paying extra.	Developers experimenting across models. Apps that want fallback logic.	Therapy apps, customer service, any voice agent where emotion matters.	Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths	Excellent prompt understanding Built into ChatGPT — no extra subscription Good at composition + concepts	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Detects + mirrors emotional tone EVI (Empathic Voice Interface) feels different Expressive voice output	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy
Weaknesses	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control	Slight markup over direct API Some provider features not exposed	Niche use case Pricing ramps fast	Cold starts on less-popular models Pricing gets real at scale
Kai's verdict	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	S-tier for model-shopping. I use this for every prototype before committing.	A-tier in its niche. The only one that actually gets emotion right.	S-tier for open-source model APIs. The default in this space.
