Strengths	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy	Very strong motion + physics Often beats Runway on realism Great price	Great voice mode Huge plugin/custom GPT ecosystem Strong image generation (DALL-E built in) Code Interpreter	Train your own models on your style/character Great for game art + concept art Generous free tier
Weaknesses	Cold starts on less-popular models Pricing gets real at scale	UX is rough for English speakers Queue times	Reasoning quality varies by mode Can be verbose Confabulates on niche facts	General output behind Midjourney Can be overwhelming
Kai's verdict	S-tier for open-source model APIs. The default in this space.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.	A-tier for creators training custom looks. B-tier for general use.
