Category	Dev Platform	Dev Platform	Image	Image
Pricing	Pay per second of compute	Pay per token — model-dependent	Free + included with Creative Cloud	$10-$120/mo
Best for	Developers using open-source models (Flux, SDXL, Whisper, etc).	Developers experimenting across models. Apps that want fallback logic.	Anyone in Creative Cloud. Brands that need copyright clarity.	Anyone who wants beautiful images without thinking about prompts.
Strengths	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Trained on licensed content — commercially safe Generative Fill in Photoshop is incredible Native to Adobe ecosystem	Best-in-class art direction v7 is stunning Great style consistency
Weaknesses	Cold starts on less-popular models Pricing gets real at scale	Slight markup over direct API Some provider features not exposed	Aesthetic ceiling below Midjourney Tied to Adobe subscription	No free tier Discord-first UX (web now available) Less controllable than ComfyUI
Kai's verdict	S-tier for open-source model APIs. The default in this space.	S-tier for model-shopping. I use this for every prototype before committing.	S-tier inside Photoshop (Generative Fill). B-tier standalone.	S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
