Strengths	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Live access to X posts for real-time events Less restrictive on edgy questions Fast inference on Grok-3 and up	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	Writing quality trails Claude/ChatGPT Political bias debates Ecosystem is just X	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.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	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.
